Swimming Pool Filter Multi-Port Valves

clock August 24, 2017 10:03 by author medallionpools |

The multi-port valve may be attached on the top or on the side of your DE or sand 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.

Multi-Port Valve Functions
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 swimming 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 re-circulate function bypasses your filter and might be used when you use floc or alum in your pool (to clear up a cloudy pool).

Check your pump’s strainer basket weekly (at the minimum) to remove any leaves or debris. Depending on the conditions around your 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.

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 decisions to make!

Deep end options
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 pool liner. This gives you a more built in look.

Shallow end options
Maybe you don’t care for the normal white entryway step. This can be replaced by liner steps that can fit into the corner, extend the width of the pool, or in the center of the shallow end. The top liner step can also be manufactured larger to make a sun lounger area.

Pool shape & size
Pool shape and size 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 referred to by manufacturers differently, but may include 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.

Pool lighting
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 available with over 10 color combinations. The LED light offers a remote similar to how you’d use gas logs.

Vinyl Liner Maintenance

The vinyl liner in your pool very durable, designed to give you many years of enjoyment. Proper water chemistry is critical to the life of your liner. While the title of this article is Vinyl Liner Maintenance, the bad maintenance practices outlined here will also cause problems for concrete and fiberglass pools.

When using granular chlorine, if you pour a cup in one location, it could fall to the bottom and bleach the liner. That bleach area will start to become very thin and develop holes. Your liner will then start to lose water. Broadcast it slowly around your pool and brush off any that falls to the bottom. Be sure to follow all safety instructions found on the label.

If you use chlorine tablets and do not use a chlorine feeder and put them in your skimmer basket, your liner might bleach just below the skimmer and become very thin, then start to leak. You should use a chlorine feeder for these tablets. Tablets will tend to lower the pH and Alkalinity levels of your pool water. Your liner will lose its elasticity if levels remain low. The liner may also become brittle and could split.

You should have your local pool dealer check your swimming pool water on a regular basis so you can maintain proper levels. Test strips are also available for you to use if you are not close to a pool store. We have stories of customers who still have their original liner from over 25 years ago. You may also be able to do this with proper care and water chemistry.

Factors Affecting Quality Of Pool Water

Here are some basic descriptions of the factors that can affect the quality of your pool water. Please note that all information is generic and will not apply exactly the same way to all swimming pools. Be sure to discuss any questions or concerns with your local pool professional.


Bathing Load
The more people that use your pool, the more disinfectant you will need to properly sanitize it and control algae.

Sunlight
The warmer the weather, the faster you will lose the residual disinfectant needed in the pool to control bacteria. You can make the residual last longer by maintaining the proper stabilizer level.

Water Temperature
Most pool chemicals will not last as long when water temperature gets warmer. The acceleration is even greater when the water temperature exceeds 85 degrees.

Wind & Rain
When you experience periods of wind & rain, these conditions will carry dust, bacteria and even algae spores into your pool. These will overwork your current chemicals, reducing their ability to properly sanitize your pool.

PH- When the PH level of your water rises, the ability of your pool water to disinfect bacteria will decrease. You need to maintain PH level in the 7.2-7.6 range.

Total Alkilinity
When Alkalinity level is below 80 PPM, this will affect the PH level and may cause staining in a plaster pool, or result in possible algae growth. When the alkalinity level is too high, above 130 PPM, cloudy water and scaling can occur.

How To Backwash Your Sand Filter

clock July 26, 2017 10:24 by author medallionpools |

These instructions are for a sand filter with a multiport valve. Please see your owner’s manual to verify the proper backwashing/cleaning procedure for your particular filter.

It is important to remember that you only need to backwash if the pressure gauge is reading too high or the flow of water from your return into the pool has slowed. While you are backwashing you will need to watch the level of the water to make sure it does not go below the bottom of the skimmer. Re-fill the swimming pool if necessary. If you backwash too much, you will need to chemically re-treat the water. Follow these simple steps to backwash your filter:

1. Turn off the pump.

2. Attach a hose to the backwash port.

3. Clean the skimmer basket.

4. Turn the filter handle to the “backwash” setting (make sure you roll out the backwash hose).

5. Turn the pump on.

6. Let the pump run until the water in the sight glass on the filter is clear. Your water should start clear, then become dirty, then become clear again. This process should take approximately 1 to 1.5 minutes on average.

7. Turn off the pump and set the filter handle to the “rinse” setting then turn on the pump for 20 seconds or until the water coming out is clear.

8. Turn off the pump and return the filter handle to the “filter” setting.

9. Turn on the pump and resume normal use of the pool. The reading on your pressure gauge is now showing the normal reading for your pool.
