Winterized A 40,000 Salt Water Ingrown Pool

by Maria
(Nashville, TN)

I want to closed my pool for the winter, what I need before I do so my I check in my pool store and they said only needs is super shock , my readings are


free chlorine value is 13.31
combined chlorine is 0
total alkalinity value is 52
ph. level 7.8
calcium hardness is 130
cyan uric acid is 50

I need something more the supper shock?
Waiting for you respond,

Maria




Thanks for the question Maria

Those numbers look pretty good. There are a couple of things I'd adjust. First would be the pH. The range is 7.2 - 7.8 and you're right in there but chlorine works better at a slightly lower pH. I'd adjust it to 7.0 - 7.2 by adding about 40 oz. of acid around the perimeter, sweep, and FILTER for 12 hours.

Next is to know the salinity of the pool before you close and make an adjustment if needed to bring it to the right level. It's not vital to do it now but it'll be one less thing when Spring rolls around.

Last is to use liquid chlorine. Any super shock is usually nothing more than regular granular chlorine (calcium hypochlorite) and will raise the pH. It already has a pH of 12. By using liquid the pH won't rise as much.

Those are the only things I'd look into.

I hope this has answered your question to your satisfaction.

How to Winterize My Pool
by: Imtiaz

I bought a house with a pool. I need help with winterizing it. I believe the previous owner had winterized it from the past summer and they never removed the cover. I need to make sure that all the equipment is winterized and need help with the chemicals. Thanks in advance.

Winterization Plug Popped Out. Should I Be Worried ?

by Zak
(Ohio)

This year I decided to close the pool myself. Everything seemed to have gone well but when I went to open the pool today I noticed one plug fell out.

Unfortunately we had the worst winter EVER with many 0 deg nights.

How much should I worry? The pool appears to be fine I did blow all the lines clear prior to plugging. Can a plug popping out allow water in and cause damage?

How can I prevent this in the future?




Thanks for the question Zak

Although I've never had this happen to me I've heard about it from other pool guys. This is what I've experienced of what may or may not happen. The following is what I've learned from them.

Most types of plugs that are used for pool winterization are called expansion plugs or freeze plugs. They're tapered rubber plugs with two stainless steel washers and a bolt passing through the center. Sometimes they can pop out due to the expansion and contraction of the water during the Winter months.

If the system is capped/plugged at the skimmer and filter the chances of water getting into the line is minimized. It's similar to a drinking straw. If you place your finger over one end and put it into a glass of water the straw won't fill with water. It's not until you release your finger is the pressure equalized and water will fill the straw.

Without seeing your pool it's difficult to say whether this happened.

My suggestion would be to blow the line out and see if any water or bubbles come out. The line may not have been frozen.

If it was frozen it could have burst and you may have a problem. You can fill the pool to the proper level, add the chems and balance it out then see if you have any loss of pressure, bubbles back into the pool through the returns, or loss of water. From my experience you need to have everything up and running and see what's happening before you start to troubleshoot.

Obviously there's a chance of water getting into the pipes, freezing, then causing the pipe to expand and break but the only way to know is to run the system and watch for bubbles, loss of water, etc...

The best way to ensure the plugs don't pop out of to get the right size for your pool's plumbing and ti install it properly. Pool plugs are commonly available in 14 sizes, from 00 (fits 1/4in. holes) to 13 (fits 2-2.5in. holes).

Things do happen on occasion such as your issue and that's why it's so important to take care of the details. Doing all the small things well add up.

I hope this has answered your question to your satisfaction.
