Swimming Pool Filter Multi-Port Valves

clock July 13, 2016 11:00 by author medallionpools |

This is a valve that may be attached on the top or on the side of your sand or DE filter. Six main functions are controlled with this valve plus one winterizing function. Please keep in mind that this article is for general information purposes only. Be sure to read your filter’s manual and follow the manufacturer’s instructions.

The main functions are:

1. Filter

2. Backwash

3. Rinse

4. Recirculate

5. Close

6. Waste

The normal operating mode will be in the filter position. Water from the pool is going thru the filter and being cleaned and returning to the pool. You can vacuum your pool in the filter position. The debris from the pool goes into the filter. When you complete the vacuum process, remove your cleaning equipment and turn the pump off. Place the multiport handle in the backwash position. Turn pump on. Water will go out the backwash hose and fill up the sight glass on side of the value. When it is clear, turn pump off and put valve in rinse function. Turn pump on for about 20 seconds. This clears debris from plumbing lines inside the filter.

If you have periods of heavy rain and notice the water level of your pool is getting very high, turn the pump off and place the multiport handle in the waste position. Turn pump on. This bypasses the filter and lets water go directly out the backwash hose. You can also vacuum your pool in this position if your pool has a lot of water or you have a lot of dirt in the bottom of the pool you don’t want to vacuum into your filter media. The recirculate function bypasses your filter and might be used when you use floc or alum in your pool (helps clean a cloudy pool).

Your pump has a strainer basket that needs to be checked weekly (at the minimum) to remove any leaves or debris. Depending you the conditions around you pool you may need to check it more often. When you open the lid to remove the basket, you are letting air in your plumbing lines. Place the multiport handle in the closed position first might help keep more water in your plumbing lines. Take it off of closed and go back to filter before you turn pump on.



How Do I Put Chlorine Tablets Into My Pool

Many pool sanitizer options are now available for your swimming pool. If your choice is chlorine tablets or chlorine sticks, what is the best way to get the product in the water? Chlorine tablets are usually available in 1” or 3” size. The stick is normally a 3” in diameter but much longer than the tablet.

You might think you would put them into your skimmer or use a floater. If you place them into your skimmer, chlorine residue could cause your liner to turn white in front of your skimmer. It can also damage the skimmer itself, your pump, your filter, and your plumbing lines. You also have no way to control the amount of chlorine going in your pool. The floater is a better choice. By using the floater, you may want to use the 1” size tablets. Since you do not have water rapidly going over the tablets to dissolve them, the 1” size would be better.

By trying to place them inside your pumps strainer basket, you could be doing harm to your equipment and still have no way to control the amount of chlorine getting into your pool. You have to estimate how many tablets or sticks to put in the basket. They would dissolve quickly and now your pool will have too high a chlorine reading.

The best way to use chlorine tablets or sticks, is with an Automatic Chlorinator. This unit would be installed in the pool return liner. If you have a pool heater, it should be installed after the heater. The chlorinator has a control value that you can regulate the proper amount of chlorine getting into your pool and you are not harming your liner or pool equipment.



Chlorine

This is still one of the most commonly used disinfectants in a swimming pool. Several types of Chlorine Compounds are available.

1. Unstabilized Chlorine

A. Calcium Hypochlorite- granular and will not dissolve completely in water. Will tend to leave a lot of residue in the bottom of your pool.

B. This chemical will need to be put into your pool.

C. Stabilizer will also have to be added to extend the life of your chlorine.

2. Stabilized Chlorine

A. Tri-chlor- This is the solid form of chlorine and could be either chlorine tablets ( 3” or 1” ), or chlorine sticks.

B. Di-chlor- this is in granular form and is slow dissolving.

C. This product line has stabilizer built into it.

D. If you use a floater with chlorine tablets, you may need to add some stabilizer because the tablets will not dissolve quickly enough.

Chlorine is susceptible to rapid decomposition from the sun’s ultra-violet rays. In order to improve the effectiveness of chlorine and reduce its loss, the stabilizer or Cyanuric acid level will need to be maintained above 40 PPM. The Free chlorine level of your pool water is what is the most important. That level should be maintained between 1.0 – 2.0 PPM. Your pool could have a chlorine reading and still have algae because the free chlorine level is too low.



What Options Do I Want To Add To My Pool

Now that you have made the decision to install an inground vinyl liner swimming pool, you have many option choices. In the deep end of your pool, you may want to install a Swimout or In Pool Seat. One item would take the place of an 8’ panel and the other a 6’ panel. The Swimout is 8’ in length and you have room to sit in, lean back in and steps to exit the pool. The In Pool Seat is 6’ and designed for two people to sit in. Both of these items extend beyond the pool edge.

All of the above options are also available in a version that is covered by the liner. This gives you a more built in look.

What can you do in the shallow end? Maybe you do not like the normal white entry way step. This step can be replaced by liner steps that can fit into the corner, extend the width of the pool or be placed in the center of the shallow end. The top liner step can also be manufactured larger to make a sun lounger area.

Would you like lighting for your pool? Some manufacturers offer a Dry Niche Light. This light will have a lid like a skimmer and you get to the light bulb by lifting the lid from your pool deck. This type of light will use a regular flood light bulb. A LED version is also now available with over 10 color combinations. The LED light offers a remote just like gas logs might have.

What about pool shape. This is only limited by your imagination. Most liner manufactures now have equipment in place to do just about any size or shape you want. The many different shapes are called by different names from the manufacturers. Names like, Rectangle, Grecian, Lazy L, True L, Freedom Lake, Chesdin, 4’ Radius Corners, 2’ Reverse Radius Corners, etc. You no longer have to settle for the box shape pool. Discuss these many design options with your local Medallion Pool Dealer.



Swimming Pool Equipment Maintenance Tips

clock June 29, 2016 09:30 by author medallionpools |

Here are just a couple of quick equipment maintenance tips to help keep things running smoothly. Be sure to read your equipment manuals and follow the manufacturers’ recommendations.

If you have a Sand or DE filter you probably have a Multi-Port Value that either attaches to the top of your filter or is mounted on the side of your filter. The handle you push down when you want to change a function has a spring under it which you can’t see. It is a good idea once or twice during the pool season, turn your pump off, push the handle down and spray some type of lubricant under the handle to keep the spring lubricated.

The pump has a lid that has an o-ring either that mounts on the lid or has a grove in the pump it mounts to. This o-ring needs to be lubricated with o-ring lube to help it seal better and make it easier for you to remove the pump lid to clean the strainer basket. If the o-ring does not seal properly, your pump may not prime or the strainer basket may not fill up completely with water. You will notice a lot of air bubbles.

On the pump you also have drain plugs. Most of these drain plugs have a small o-ring. If this o-ring is missing or broken, a lot of air will get into your filtration system and the pump may have a hard time priming or the strainer basket may not fill up with water. Make sure the o-ring is in place. You can wrap a small amount of Teflon tape around the threads and cover that with o-ring lube.

If you have an Automatic Chlorinator, this unit has an o-ring. This o-ring is either mounted in the top of the lid or on the chlorinator itself. This o-ring will wear out and become brittle and may have some small breaks in it. This could cause air leaks. Replace if needed and cover with o-ring lube.
