Vinyl Liner Maintenance

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

When using granular chlorine, if you pour in 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, this could cause your liner to bleach just below the skimmer and become very thin and 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 these levels stay low and the liner will become brittle and could split.

You should have your local pool dealer check your 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 have their original liner in there pool from over 25 years ago. You may also be able to do this with proper care and water chemistry.



Why Does My Swimming Pool Get Cloudy

clock July 14, 2016 07:00 by author medallionpools |

Many factors go into answering this question. Some possible reasons are;

1. Dirty filter or baskets (skimmer & strainer)

2. Not running the filter & pump long enough each day

3. Chemical problem

Lets discuss each.

If you have a sand filter, the sand may need to be replaced or just try getting the proper pool chemical and clean the sand first. Sand should be cleaned several times a season and changed every 3-5 years (this could vary depending on pool and chemical usage). If you have a cartridge filter, make sure you have a clean cartridge. If you have a DE filter, make sure you have enough DE Powder and that the grids are clean. Every time you backwash your DE filter, you should add the recommended amount of DE powder.

A lot of customers only turn their pump on at night. With high heat and humidity, the pool water will always look cloudy. If you have a continuous use pump, your filter system can run 24/7 during the summer. The more you filter the water, the cleaner it is going to be. With a chlorine generator, make sure the unit is in the right function to produce the proper amount of chlorine from salt.

Water chemistry is the most common reason for cloudy water. All these chemicals have to be in the proper range or cloudy water could be the result;

Chlorine reading- 1.5-2.0

PH- 7.4-7.6

Alkalinity- 110PPM

Calcium Hardness- 250 +

Stabilizer- 40 PPM

Please note that based on the chemical system you are using, these recommended readings may vary. If you bring a sample of your pool water to your local Medallion dealer, they can test it and give you the advice you need to eliminate cloudy water.



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.
