8. WINTERIZING THE POOL
(continued)
8.2 PREPARING THE WATER
8.2.1Keep average water parameters in the weeks before closing your pool.
When closing, use a pool closure kit sold at your local dealer. This kit contains algaecide and chlorine specially made
for winterizing swimming pools. Using these kits will reduce the amount of chemical products when you restart your
pool in the spring.
Clean the bottom of the pool of any dirt, leaves or sand before lowering the water level.
8.2.2 Empty your pool so that the water level is between 6 inches and 20 inches (15 cm and 50 cm) under the water
return. The water return hole can be blocked or closed once the water level is lowered. THE HOLE UNDER THE
SKIMMER MUST STAY OPENED.
Keep the skimmer on the pool. Do not let water accumulate in it. Make sure the water that will go through the
skimmer will drain as far as possible from the pool to avoid causing ground movements.
For regions where freezing is greater, we recommend lowering the water level between 15 in and 20 in. (40 cm and
50 cm) under the water return. Check with your local dealer to know his recommendations as to the level of water to
be kept during winterization.
It is also recommended to check the water level during autumn once the winterization is done before the pool water
freezes. If the level rises drastically, it is recommended to empty this water to bring the water back to the acceptable
level.
DO NOT EMPTY THE POOL COMPLETELY. This could cause your liner to move, it will also put your pool at risk of ying
upwind and causing signi cant damage to your property or your neighbors. It could also cause serious injury.
If you have a main drain, it is recommended to use antifreeze specially designed for swimming pools in order to avoid
pipes from freezing. To do so, once the pool is emptied unplug the pipe that connect the main drain to your ltration
system. Make sure the pipe is above water level (to prevent the pool water from emptying through the hole). Fill this
pipe with antifreeze until you see antifreeze coming out of the main drain of the pool. (You will not be able to ll the
pipe since the water pushed by the anti-freeze will go into the pool by the principle of communicating vessels.)
Make sure that the pipe remains higher than the water level all winter by tying it to a top ledge.
