If you are putting in a salt water pool or thinking about changing your existing pool to salt, there are a number of things you must consider. Among these things is your pool pump. Like a traditional pool, you need to have a pump in your pool. Pump options vary, and sometimes you don't even have to replace your it if you are converting to a salt system. However, before you purchase a salt water pool pump, take a moment to learn about your options.
In most cases, you can use your traditional pump. There may be a few problems with calcium build up if you do not keep you chemical levels in check, but in general, a typical pump works just fine. This is good news for people wishing to convert to a salt system. There may be a few problems with salt conversion if you have a stainless steel pump, however, as the salt can work against the stainless steel and cause a number of problems. Some stainless steel systems can work well, depending on the way they operate. If you've converting an old chlorine pool to a salt system, check with the pump's manufacturer to see if your pump can be used as a salt pump.
A salt water pool pump works quite simply, just like other pumps. Water from your pool is sucked into the pump through an intake port. The water is filtered through the pump basket, which you'll have to clean regularly. It is then pushed through the pump and back into the pool through the discharge pump. The only difference is that you also have a salt cell attached to the system. This cell uses electricity to produce chlorination, keeping your pool clean. This should keep your water blue and clean, just like it would be in a typical pool.
When choosing one, if yours needs to be replaced of if you do not currently have a pool, look for one that works well in your price range. Yes, pumps can be expensive, but a new one should last for many seasons if you maintain your pool. With a new equipment, make sure that the manufacturer has noted that the it can be used with a salt system. In addition, check out the warranties given with the device, as well as the colors and styles if the salt water pool pump will be in the open where everyone can see it.
Is a salt swimming pool the right choice for you? That's not a question you can answer by discussing pump options alone. There are both advantages and disadvantages to this system so it is important that you learn about both the benefits and the downfalls before installing this kind of pool system.
Swimming pool sand filters are one of the ways to keep your pool crystal clear and clean. This type of product uses sand as a means to collect and remove debris from a body of water. Sand is contained in a vessel or tank, water is pumped into the top of the tank, and into the internal distributor. This allows the pool water to "rain down" and flow through the media. As the water flows through, dirt and debris are collected and removed from the water. The debris is held behind and the clean water is returned to the swimming pool.
What are some of the items found and associated with a type of filter?
1. Multi Port Valve OR Control Valve
What are some of the functions found on a standard Multi Port Valve?
o FILTER - For normal filtering and vacuuming.
o BACKWASH - For cleaning the filter bed of accumulated debris.
o RINSE - Use after completing the backwash cycle to ensure all dirty water is rinsed from the tank to waste.
o WASTE - By-passes the tank for draining or lowering the pool water level and for vacuuming heavy debris directly to the waste line.
o RECIRCULATE - Water is recirculated through the valve by-passing the filter.
o CLOSED - Shuts off the flow from the pump to the filter
Internal Parts
2. Tank Or Vessel - Main body of the unit.
3. Top Diffuser - Allows the pool water to enter the tank and distribute the water inside the tank.
4. Media - Captures the dirt and debris from the pool water as it flows through.
5. Laterals - Located under the media, allows the pool water to exit the tank and flow back to the pool.
How are sand filters cleaned?
Most filters come equipped with a valve, commonly referred to as a Multi Port Valve. The Multi Port Valve has various settings allowing water flow to be directed in many direct directions. One of the directions is BACKWASH. In the backwash mode the water inside the tank is made to flow in reverse. Instead of the water flowing from the top of the tank down, the water from the pool is fed into the bottom of the tank through the laterals. This causes the sand to be churned, the dirt and debris which has been contained is flushed out of the tank through a separate waste line. Many Multi Port Valves have a sight glass for viewing this process. As the water is backwashed, use the sight glass to inspect the water, as the water becomes visually clean the backwash should be considered finished, the pump stopped and the valve now put in the RINSE mode. Reenergizing the pump in the rinse mode allows the water to flow in the standard operating direction and allows settling to occur in the tank. Dirty Water is flushed out to waste during this process.
NOTE: This process will lower the water level of the pool. Once the pool level is lowered additional chemicals may be needed. Retesting of the water will be required to determine the type and amount of chemicals which will be required.
What if backwashing is not enough?
If backwashing does not "clean" the media, the time has come to disassemble the unit, empty the tank and replace the sand. The media will deteriorate over a period of time, become hard and crusty, and forming channels. When this takes place, backwashing will not be enough to allow proper filtration. It is important to remember the following when performing this task.
1. If the filter has not been disassembled for some time, when removing the multi port valve, top dome or top half of the tank, remember to have new o-rings available which will be in the area of disassembly. Old o-rings stretch and crack over a period of time and need to be replaced periodically.
2. Carefully remove the old media from the tank. This can be accomplished by scooping or by using a sand vac tool (a tool which by using a garden hose and exhaust hose, vacuums the sand out of the filter tank.
3. Inspect the bottom laterals, checking for damage or cracks. Replace any laterals which are defective to prevent by-passing of sand back to the swimming pool.
4. Prepare to refill the tank with the new media (Check the instruction manual for the filter and use the size and type which is recommended).
5. Fill the tank half full with clean water
6. Slowly and carefully add the new media to the tank. Use caution not to damage the laterals during this process. Add the correct amount for the size filter being serviced.
7. Reassemble all parts removed, top half, dome, and valve, replace o-rings as required.
8. Position the multi port valve in the RINSE position to settle the new media, check for leaks, once settled, turn off pump and return the valve setting to the filter position. Restart Pool Pump and begin normal operation.
How often does the sand need to be changed?
Filter size, pool usage, bather load and weather conditions will dictate the time frame for changing and recharging the filter.
These types of filters have been utilized for many years as an effective means of swimming pool water filtration. Maintaining the filter and valve will provide many years of service, keeping your water crystal clear, enjoyable and ready for fun.

Filtration is one of the most important factors in the circulation system of your pool to keeping it clean. There are three types of swimming pool filters available for pool owners. Sand filters, Cartridge filters and DE Filters. It is important to know which filter you have on your pool and how to maintain and operate it. Each of these pool filters have their own advantages and disadvantages. With any pool filter you choose it is important to keep the proper sizing in mind. Proper sizing refers to the pool volume and the size of pool pump.
Sand Filters:
Sand filters work by pushing water through a bed of sand and into laterals. Sand filters generally have the advantage of being reliable and simple to operate. Sand filters are capable of continually filtering water with out shutting off the pump for days on end. As long as proper water balance is maintained along with regular cleaning cycles the sand inside the filter well be good for up to 10 years. If you are having a problem keeping your water clean and clear only, change the sand as a last resort, other problems in the pool chemistry are probably the cause.
Backwashing Your Sand Filter:
When the filter becomes dirty pressure will build up, and you can see this on the pressure gauge. When the pressure gauge reads approximately 5 to 7 PSI above the normal operating pressure you know that the filter is dirty and it is time to backwash. Backwashing is an easy process. Backing washing is done by first turning the pump OFF. Note: Always turn the pump off while moving the filter multi port valve. Once the pump is off, turn the multi-port valve on the filter from the 'filter' position to the 'backwash' position. Once the filter is in the backwash position turn the pump back on. The water is then reversed through the sand by the pump. The dirty water gets sent out the waste line (usually into the yard). High concentrations of chlorine can kill grass so it is important to know what the chlorine level is in the pool while backwashing. A 1 to 2 ppm range should be safe it avoid killing the grass. Once the water coming out the waste line is turns from dirty to clean (may take up to 3 min.) turn the pump back off. Once the pump is off move the multi-port valve back from the backwash position to the rinse position. Turn the pump back on and let it run for about 20 seconds. Then turn the pump back off and move it to the filter position.
Lets recap the backwashing steps:
Filter Position-> Pump Off -> Backwash Position-> Pump On for 2 min. ->Pump Off -> Rinse Position-> Pump On for 30 Seconds -> Pump Off -> Filter Position
Diatomaceous earth filters:
Diatomaceous earth filters use grids inside coated with diatomaceous earth or DE for filtration. DE filters have the advantage of filtering to the finest particles or microns. However, they have been considered the most hassle to operate. For proper operation of a DE filter it must be turned off for about 4 hours everyday. This is to allow the DE to drop and be recoated when the pump comes back on.
Back washing a DE filter:
Like sand filters they also require backwashing when the pressure rises to about 6 pound above the normal operating pressure. After backingwashing you must recoat the filter grids with new DE. This is done by feeding DE through the skimmer so it gets pumped into the filter tank. DE is a white powder substance that must be purchased at pool store. About twice a year DE filters should be taken apart and the grids cleaned. Most DE filters have a multi port valve on them used for backwashing. Backwashing is an easy process. Backingwashing is done by first turning the pump OFF. Note: Always turn the pump off while moving the filter valve. Once the pump is off, turn the multi-port valve on the filter from the 'filter' position to the 'backwash' position. Once the filter is in the backwash position turn the pump back on. The water is then reversed through the grids by the pump. The dirty water with old DE gets wasted out the waste line (usually into the yard). High concentrations of chlorine can kill grass so it is important to know that the chlorine level in the pool is low while backwashing. Once the water coming out the waste line turns from dirty to clean (may take up to 3 min.) turn the pump back off. Once the pump is off move the multi-port valve back from the backwash position to the rinse position. Turn the pump back on and let it run for about 20 seconds. Then turn the pump back off and move it to the filter position. Now its time to recharge the DE in the tank. Refer to the label on the filter for the proper about of DE to be added, it should say how many pounds are required for a recharge. Turn the pump back on and go over to the pool skimmer. Add the recommended number of pounds to the skimmer slowly. It is best to make a slurry in a bucket then slowly poor it into the skimmer so avoid clogging. At this point it is a good idea to take a look at the return line in the pool to be sure that the DE is being caught in the filter. If you have white powder spraying out the return jets in the pool then you know you have a problem in you grids or the valve is set in the wrong position.
Lets recap the backwashing steps for a DE filter:
Filter Position-> Pump Off -> Backwash Position-> Pump On for 2 min. ->Pump Off -> Rinse Position-> Pump On for 30 Seconds -> Pump Off -> Filter Position-> Pump On->Recharge filter with DE from skimmer

The chlorinator itself is like a small chlorine production factory. You add salt to the pool, your pump and filtration process pass water over electrodes in the chlorination, converting salt to chlorine.
Nowadays, most new pools are built with a chlorinator system and system costs are now cheaper than ever. Chlorine has a bad smell, heavy and worrisome to handle. You don't have to put up with the harmful effects of chlorine i.e. degrading costumes, more friendly to hair and skin. Salt is softer on skin and naturally feels better to swim in than standard chlorinated water.
As technology has moved on, newer chlorinators can clean themselves and built in controllers and timers regulate the Chlorine production. The amount of salt needed to effectively chlorinate a pool is only about one fifth of seawater salt levels and it never evaporates.
Getting the salt levels correct for your Chlorinator and size of pool can extend the life of your salt cell. The salt cell can wear out over time or calcium deposits build up and they need cleaning. Replacing this salt cell is the biggest single maintenance cost. Shock treatments and other balancers are still needed but manual maintenance is usually less than a same size chlorine pool. Overall cost comparisons vary but in general with costs coming out roughly similar or slightly less for saltwater.
There are many different brands of salt chlorinator on the market and it is a bit of a minefield to chose. Self cleaning require least maintenance and automatic timers are useful. Finding the right replacement salt cell can be tricky. Cross checking photos and cell lengths and other dimensions are a good idea if buying online. There are many generic salt cells on the market now for popular brands. This can save money and better quality cells come with warranties and are made of high quality components.
