Questions on Water Softener
Basically, the resin or mineral inside the mineral tank is specially designed to remove “hard” particles of lime and calcium, by a simple ion exchange process. The resin beads inside the softener tank have a different or opposite electrical charge than the dissolved particles of the incoming water. Because of this electrical charge difference, the dissolved particles suspended in your water will cling to the resin beads on contact, thereby ridding the water of these particles, causing the water exiting the unit to be “soft”. The resin has a limit to how much of these hardness particles it can hold, which is why there are many different sizes of softeners and also why regeneration or brining is required.
No. Your water must be safe to drink before you condition the water with a softener. If you are concerned about the safety of your drinking water, contact your local health department about getting a bacteria test, or full lab analysis on your water.
The minerals that make water hard usually contain calcium and magnesium. Calcium and magnesium in water interfere with the cleaning action of soap and detergent. They do this by combining with soap or detergent and forming a scum that does not dissolve in water. Because these minerals react with soap and detergent, they remove the soap and detergent, thereby reducing the effectiveness of these cleaning agents. You can overcome this by adding more soap or detergent. However, the scum that is formed can adhere to what is being washed, making it appear dingy.
An automatic water softener connected to water supply pipes removes magnesium and calcium from water and replaces them with a trace amount of sodium. Sodium does not react with soap or detergents. This will reduce the amount of soap you would need to use, and insures it will not remain in or on the item being washed, whether the item is tile, glassware, clothes, skin or hair.
With the proper pretreatment and maintenance, the average water softener will not need its resins replaced in its lifetime (20 + years). It is impossible to accurately determine the life of resin since so many factors contribute to the degradation of the resin itself. Note: Proper pretreatment can be a simple as a sediment filter or as complex as chemical injection system combined with a multimedia bed, this is determined by having your water tested.
1. Many dealers will advertise a no salt water conditioner. Any brand of water conditioner can be operated without using salt. This is done by using a salt substitute, potassium chloride. It generally more expensive compared to regular salt (sodium chloride), and can be difficult to find in some areas. Also, it is generally recommended you increase the salt setting on your control valve by about 10%, when using a salt substitute.
2. Some companies offer a variety of devices to soften your water that do not use salt, or anything else to regenerate their product. Buyers beware! If a cost effective and reliable technology had been developed that could replace a resin based water conditioner, then everyone would be selling it.
It depends on how often your system needs to regenerate. The more your softener regenerates the more salt you will consume. As for the salt level in the brine tank, you can let the salt get down to the point inside the tank where you can see the water just above the salt. When you see water above the salt, it is time to add more! Generally, you will add salt to your brine tank about every 8 weeks.
1. An average softener with 1 cu. ft. of resins (30,000 grain, 10 ” x 44 ” tank) should use about 6-8 lbs. per regeneration to achieve an economical 24,000 grain capacity (hardness in grains divided into grains of capacity results in the gallons of water that can be treated before resins is exhausted).
2. We sell only metered valves with our Watts brand softener packages, since they tend to use less salt than a non-metered unit (i.e. one set to regenerate every so many days with no regards for actual water used).
3. The national average is 60 lbs. per month, but that can vary depending upon the quantity and the quality of water being treated.
We recommend buying salt for your water softener that is very clean; around the 99.5% salt content and up. All softeners can use Potassium Chloride in place of salt. Potassium Chloride tends to melt when it gets wet, sometimes forming a “bridge” inside the salt tank, so we recommend filling the Brine tank only halfway or a bit more when using Potassium Chloride, so you can easily monitor it going down inside the tank after the unit regenerates.
The salt not going down could be due to many different reasons.
1. Valve is not regenerating due to a mechanical problem.
2. Salt may be bridged (become solid) above water that is at the bottom of the salt tank.
3. If you have been using pellet salt for many years you could have a lot of undissolved residue at the bottom. This residue will not dissolve and also can block water flow in and out of the salt tank.
4. The valve could be failing to draw the brine solution out and if you have a float shut off in the brine tank, it would be prevent the salt tank from overflowing (which it would do if the float shut off was not there).
5. The brine refill control could be clogged, prevent water to refill the salt tank.
(Note: It is highly recommended that you contact an experienced water quality specialist to trouble shoot any problem with your equipment.)
There are several things that could cause you to still be getting staining.
- It is critical that your system never run empty of salt.
- It is important that the time of day be kept correct and that no one uses water between 2 a.m. – 3 a.m. when the system is regenerating. While the system is in regeneration, any water used would be unconditioned (coming straight from the well).
- It could be your resin tank is too small to handle all the iron. A. What size is the resin tank? B. What is the level of Iron and Hardness of the water?
- It could be you are not regenerating often enough, or using enough salt per regeneration. A. How often does your softener regenerate? B. How many people are using the water? C. How much salt are you using per month?
- It could be that your iron content exceeds the recommended maximum. (1 cu.ft. of resin can effectively remove up to 3 parts per million iron with out additional treatment.)
- On rare occasions the iron could be coming from just the hot water tank. If it is more than 20 years old it could be rusting out on the inside, thus putting iron back into the water. This is also true in older homes, again over 20 years old, that used galvanized plumbing. Above are the common reasons a working water softener might still be allowing you to get staining.
For additional help and recommendations, call or contact an experienced water quality specialist.
Water softeners do not remove most taste and odor problems (although they can remove the metallic taste of iron in water).
- Odors are typically caused by hydrogen sulfide (“rotten egg smell”) in wells or “bleach” smell in chlorine treated water; both of these causes can be resolved using an activated carbon filter in conjunction with a water softener.
- The self-sacrificing rod installed in your hot water heater can sometimes be the cause of your odor in the hot water. Having a qualified plumber replace this rod could solve this problem.
To offer a proper and accurate recommendation for any system(s) needed to correct your water problems, we need current and accurate water test results. Public water suppliers have the information available to you by simply calling them and requesting to know the level of Hardness, Iron and pH of your water. If you have a private well, simply obtain a water test kit from a local hardware store, of you can purchase one of our test kits through a qualified water quality specialist.
If you have public water, simply contact the office where you pay your water bill. They should have current water testing records on file. If you are on a private water system, then contact your county health department to see about having your water tested, or you can buy a Home Water Test kit available from us at this link! Your water test results should show levels of hardness, Iron (what type of Iron you have), pH, Hydrogen Sulfide (for rotten egg odor), Nitrates and Total Dissolved Solids (TDS).
Filter systems are sized based on a couple of factors: (1) type and amount of dissolved mineral present in your water; (2) your home’s flow rate, which is typically based on the number of people present in the home. For filter systems, this information simply tells us what the fastest rate your water will travel through our units would be, and how much water in gallons per day is being used. Water softeners are sized based on the total hardness of your water, and the number of people in the home. Most all-residential applications have around an average 5 GPM flow rate. Typically, the higher the flow rate of your water going through the unit, the larger the mineral tank will be to handle the larger water flow rate. With a larger tank, the filtering media or resin will be physically deeper thereby permitting the water flowing down through it to be in contact with the media longer. Contact time is important, as the media/resin inside the tank needs to be in contact with your water for a long enough period of time, ensuring all dissolved impurities are removed before it leaves the tank.
You can get a fairly close idea of your water flow rate by simply running water at full open position through either an outside garden hose faucet or with your bathtub faucet. Example: Turn the faucet on to the full open position… then quickly put the gallon container under the full flow of water. Immediately start timing how many seconds it takes to fill the container all the way up. If it fills the container up in 15 seconds, you simply divide 60 seconds (1 minute)…by 15 seconds (the amount of time it took to fill the container up). The answer is 4, so your flow rate would be very close to 4 GPM! We recommend that you order a unit that would handle at least 4 GPM. It would be over size the unit to ensure you are getting a unit with plenty of GPM flow capacity.
There are basically four types of iron found in water, they are:
- Oxidized Iron contains red particles easily visible as the water is drawn from the faucet.
- Soluble or “Clear Water Iron” is very common, and will develop red particles in the water after water is drawn from the faucet, and is exposed to the air for a period of time. The iron particles actually “rust” once they are exposed to air.
- Colloidal Iron consists of extremely small particles of oxidized iron particles suspended in water. This type iron looks more like cloudy, colored water, instead of being able to actually see small red particles of iron. This type iron will not filter well because of the extremely small particle size. (Chlorination may be required).
- Bacterial Iron consists of living organisms found in the water and piping of the well and house. You can tell if you have Bacterial Iron by looking in your toilet flush tank, and finding a reddish/green slime buildup. To confirm this, you should take a sample of this slime to your local health department for testing. This kind of iron is the hardest to get rid of. To completely eliminate this form of bacterial iron requires chlorination of the entire water system, starting with the well casing, well pump, pressure tank and the home plumbing system. (Chlorination may be required).
- Hydrogen Sulfide causes water to have a pungent “rotten egg” odor, and is easily removed using a Manganese Greensand filer.
Yes, a softener will cause some pressure loss due to the resistance from the resin bed, but excessive pressure loss can be caused by one or a combination of the following.
- On well water, this is usually due to fine sand coming from the well.
- On softeners installed in the open sunlight (mostly in Florida), a layer of algae can grow and thick pieces of this growth clog the lower distributor tube screen when they start peeling off the inside of the resin tank.
- On chlorinated water supplies, sand can get into the tank from new construction or work on water lines in the area. All of these situations are rare.
- The most common cause of pressure loss occurs on chlorinated water. The resin can be damaged by high chlorine levels and turn to mush. This has the same effect as having fine sand at the bottom of the resin tank.
Questions on Reverse Osmosis
Osmosis is the phenomenon of water flow through a semi-permeable membrane that blocks the transport of salts or other solutes through it. Osmosis is a fundamental effect in all-biological systems. Osmosis is applied to water purification and other chemical laboratory and industrial processes. When two water volumes are separated by a semi-permeable membrane, water will flow from the side of low solute concentration to the side of high solute concentration. The flow may be stopped or even reversed by applying external pressure on the side of higher concentration. This is called reverse osmosis. (R.O.) Reverse osmosis is only one stage of a typical R.O. system. Sediment and carbon filtration is normally included with an R.O. system, with each stage of filtration contributing to the purification process.
- The first stage of filtration is the sediment filter, which reduces suspended particles such as dirt, dust, and rust.
- The second stage of filtration is the carbon filter, or filters which reduce volatile organic chemicals, chlorine, and other taste and odor causing compounds.
- The heart of Reverse Osmosis is the membrane. It is responsible for rejecting up to 98% of the total dissolved solids in the water. This is where the purification takes place.
In the natural cycle of water, water that began its life as rain and eventually found its way to your tap has come in contact with many sources of potential contaminant. The various minerals and salts that have been dissolved by the water during this cycle are called Total Dissolved Solids (TDS).
Reduction of mineral components that make up total dissolved solids will vary up to a maximum of 99.8% depending on water chemistry and pressure.
Faucet-Mount and Pitcher filtration systems on the market are able to reduce certain contaminates from your water based upon the use of granular activated carbon, or in some cases carbon blocks. Some units include additional filter media that will reduce some heavy metals as well. These type of devices are limited to the types of contaminates that they can effectively removed from your water based upon the type and amount of carbon contained with in the filter.
The Watts Premier Reverse Osmosis (RO) incorporates three different types of filtration technology in order to provide the best quality water to the user. The first stage is a sediment filter which removes larger particles and sediment from your water. The second and third stage with in our RO is our carbon block filter. Watts Premier uses only high quality independently certified carbon blocks. This additional certification on our carbon blocks ensures the consistency and integrity of the carbon block in each system we sell. These carbon blocks are able to reduce many contaminants with in your drinking water. The work horse of our system, the RO membrane, is next and is where the main filtration takes place to reduce any remaining contaminates or up to 97.9% of impurities in the water. The RO membrane is responsible for reducing many of the difficult water contaminants such as arsenic, chromium, radium and total dissolved solids. The fifth and final stage is a granular activated carbon filter which polishes your drinking water just prior to you drinking it. The combination of these technologies, mainly with the use of the RO membrane, is how the RO system can provide to you water that is bottled water quality.
While a health claim can not be made because of intangibles such as regular maintenance, these items are too large to pass through the TFM membrane. NSF’s rating for reduction of Giardia Cysts and Cryptosporidium is 1 micron, and the TFM membrane filters down to 1/10,000th of a micron. That is 10,000 times smaller than these parasites.
A CTA (Cellulose Triacetate) membrane is a paper by-product membrane bonded to a synthetic layer. Due to its cellulose composition, a CTA membrane requires chlorine in the water source to keep bacteria from forming on it. A CTA membrane has a rejection rate of between 85-94%. CTA membranes have an average life expectancy of 18-24 months and are considered inferior to TFM membranes. Premier only uses TFM (Thin Film Membrane) membranes, which are made of a synthetic material. A TFM membrane requires the chlorine be removed prior to the water entering the membrane. A TFM membrane has a rejection percentage between 95-98%, which is much higher than the CTA membrane. A TFM membrane will last between 2-5 years. Many hospitals use TFM membranes in their hemo-dialysis (kidney) machines because of the higher purity water they produce.
They are washed down the drain. Unlike filters, the R.O. membrane is self-cleaning. As the source water flows through the module, it is divided into two streams. One stream is forced through the membrane by osmotic pressure created due to the water pressure on each side of the semi-permeable membrane. The second stream carries the rejected salts, dissolved pollutants and contaminates to the drain. Therefore, there is a minimum accumulation of debris on the pressure side of the membrane. Charcoal or carbon filters, on the other hand, become less efficient with each glass of water drawn through them. Carbon filters only remove a limited number of contaminants, some odors, and some tastes.
There is a certain percentage of water from the system that goes to the drain. This water is carrying away the impurities. These particles are too small to be caught by the filters. Premier has an automatic shut-off valve that shuts off the flow of water to the drain when the holding tank is full. This valve stops the R.O. system from continuously running water down the drain, thus conserving water via the R.O. system working only according to usage.
The typical ratio is 4 to 1, based on incoming water temperature and pressure.
Yes. Most wastewater today is recycled for golf courses and artificial lakes. The drain water is slightly higher in TDS concentration than the incoming water, but as R.O. does not add anything to the water, it can be used to water your lawn or garden.
It is the pressure of water that forces the water through the membrane for purification and flushes the rejected solids away. Low water pressure will result in reduced production and premature fouling of the membrane. The ideal pressure for operating an R.O. system is 60 PSI. Pressure below 40 PSI is generally considered insufficient, and should be boosted using a pressure booster pump.
Yes. Iron will plug a R.O. membrane, as the membrane is not able to flush iron out. Trace amounts of iron (up to 2 PPM) can be removed by a water softener. If the water contains 1 PPM or less, there is no need for concern as the membrane will usually last 1-2 years. Note: This refers to clear water iron, not red iron. The difference is that clear water iron leaves no visible signs, whereas red iron leaves a reddish brown discoloration in toilet bowls, tanks, sinks and tubs. If red iron is present, steps to remove the iron will have to be taken, otherwise the warranty will be void.
Yes. It is highly recommended. The Premier R.O. system has been designed to operate best to give high quality purified water with normal routine maintenance. By changing the pre-filters on a regular six-month basis, you will eliminate dirt and chemicals in the water that will plug the membrane. After six months of use, the carbon filters can have bacteria growing within the filter media. Your local water conditions may necessitate more frequent filter changes.
Yes. The 1st stage sediment filter must be a 5 Micron, 10″ cartridge. The 2nd stage filter is more crucial. A purification grade carbon must be used, also 10″ length. Premier recommends the customer use Premier’s G.A.C. 56 cubic inch carbon filter because our filters have more carbon than others, therefore, better filtration. The system’s various components are designed to enhance each other, thus the system will work much better. You can use other carbon filters; however, you may need to replace them more often due to their smaller volume of carbon.
No. The R.O. system can be mounted in a cabinet to either side of the kitchen sink or even mounted remotely in a garage or basement.
The module part of the R.O. system measures:
- 15 ¾” Tall x 14″ Wide x 5 ¼” Deep on the Model #4SV
- 15 ¾” Tall x 16 ¼” Wide x 5 ¼” Deep on the Model #5SV.
- The storage tank measures: 11″ Diameter x 16″ Tall
Approximately 20-25 feet with ¼” POLY tubing. For runs longer than that, use 3/8″ POLY tubing. Tubing that runs from the R.O. system to the icemaker should always be POLY tubing, not copper.
Due to R.O. water being very pure, it is what is known as “hungry water.” R.O. water can leach the minerals out of the copper tubing and may cause a metallic taste in the ice cubes and over a period of time, the copper tubing can develop pinhole leaks.
You will be able to tell by the taste and clarity of the water. For example, ice cubes made with the R.O. water are harder, clearer, and last much longer. If you take two clean glasses of the same size and put ice cubes made with R.O. water in one and the same number of ice cubes made from tap water in the other, you will notice that it takes longer for the R.O. ice cubes to melt. Not only do ice cubes made with R.O. water last longer but juices and mixed drinks made with R.O. water taste better. When ice cubes made from tap water are melted in a glass, you will most likely see unsightly sediments on the bottom. This is not so with R.O. water. Another way of determining the amount of dissolved solids removed from tap water is by the use of a conductivity meter. This meter measures the conductivity the dissolved solids impart to the water. This is converted on the meter scale into parts per million of Total Dissolved Solids (TDS). Premier offers a water sample kit for the testing of a customer’s water to determine how the TFM membrane is working and when to replace the membrane.
No. A water softener removes calcium and magnesium from the water and is usually installed at the point-of-entry (P.O.E.) of the water to the house. A water softener is good for the home’s plumbing and water related appliances, but does little to improve the taste or quality of your drinking water.
No. Calcium and magnesium (limescale) are two of the hardest minerals for the R.O. membrane to remove. Sodium (added to the water by the softener) is much easier on the membrane and it will reject 98% of all sodium in the water. A water softener will help extend the life of the membrane.
Yes. R.O. water is softened through the reverse osmosis purification process; however hard water (above 7 grains of hardness) will shorten the life of the membrane. The harder the water, the shorter the life. Example: If you incoming water is 15 grains hard, you may only get 2-3 years of life from your membrane.
