Closing An Indoor Pool For The Winter
by Savi
(Ontario, Canada)
We are planning to close our indoor pool down for the winter. What is required for this process?
All equipment is located in the basement indoors and the pool room is part of the home construction.
It is approx 20ft X 40ft with a spillover spa. Depth is 3.5 ft in approx. half of the pool and 8ft in the balance. Since we have never closed it in the last 5 years that we have had the pool, we were wondering if closing it would be the same process as closing an outdoor pool by blowing the pumps out and the dectron unit and covering the pool.
Would this be sufficient or do we have to empty the pool also? The temperature can drop quite low in the winter months in Ontario (-30C--40C) and there is no other heat source to the pool room except through the dectron unit which also controls the humidity level in the pool room but cannot run to heat the pool and air without the pumps.
Please advise
Thanks for the question Savi
I have personally not closed an indoor pool for a customer, but from my understanding the process is the same as for an outdoor pool. Blowing out all the lines and removing the water from the pump is the best way to go. You can use anti-freeze designed for pool lines, but I've always found the safest bet is the remove the water from the lines.
You can go to this link to learn how to close your pool:

You should also blow the water out any lines from the heaters and de-humidifiers.
The YMCA uses an older brand of de-humidification called a "Dry-O-Tron". It still works pretty well but it's showing the age of the unit. There's a massive amount of water going through it so it would be best to remove as much water from as much piping as you can.
There's no reason the empty the pool. Many pool owners leave their pools filled over the Winter months.
Hope this helps and have a wonderful rest of the Summer
