INSPECTION
STEP 1
Before the annual closing of the pool, check the chemical parameters of the water
(PH, alkalinity, chlorine…). A water with unadjusted parameters will degrade the liner
and could cause rust on the wall.
STEP 2
Check for any leaks in the liner. To make sure, sometime early in September, check
that the water level does not drop in a week period. If a drop in the water level is
observed, there is a leak. Repair the holes in the liner using a repair kit which can
be found at your local dealer. Check for any leaks around the skimmer opening and
water return. If a leak is found, actions must be taken immediately to repair the
problem. Check that the liner is still
fi
rmly attached to the top of the wall.
STEP 3
Check the structure of the pool. If corrosion and scratches occur on the pool wall,
you must be repair them by using an anti-rust enameling product. Rub the rusted
surface with a wire brush, apply the anti-rust product and repaint the wall to match
the repair to the color of the wall. Also check that the walljoint (joining the two ends
of the pool wall) is solid and that the screws are tight.
PREPARING THE WATER
STEP 1
Keep 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.
Empty your pool so that the water level is between 6’’ and 20’’ (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’’ and 20’’. (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
fl
ying upwind and causing signi
fi
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
fi
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
fi
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.
WINTERIZING THE FILTRATION SYSTEM
STEP 1
Disconnect all the hoses from the
fi
ltration system. Follow the instructions manuals
of the various components of your
fi
ltration system to winterize. Store all the
equipment; pump, ladder or other in a protected and closed area.
A proper winterization should only take a few hours and will make the spring open-
ing of your pool easier.
As winter approaches, the temperature of the water cools, the addition of chemicals
becomes less and less necessary. However, it is necessary to periodically check the
chemical parameters of the water in order to keep the water clean and without
deviations from the recommended values. Failure to respect these values could tar-
nish the pool liner and reduce its life span. It is recommended to winterize the pool
as late as possible (end September/beginning October) when the temperature of the
water is under 10°C (50°F). At this temperature, the proliferation of contaminants is
very slow.
Do not turn o
ff
the
fi
ltration system until the pool is completely closed. The early
closing of the system could allow the water in the pipes to freeze and break some of
the elements of the
fi
ltration system.
Neglecting to follow the winterizing will avoid the
warranty of your pool.

WINTERIZING THE POOL
In regions where freezing temperatures occur, it is common practice to close a pool
during the winter months. This is called winterizing.
All our pools were designed to stay outdoors during the winter. However, it is
necessary to follow the following directions to winterize your pool.

WATER CHEMISTRY
The pool water contains several corrosive products for the wall of the pool. It is
important to check that there are no leaks in the liner. Any leaks will cause corrosion
to the pool wall which, if not treated quickly, will reduce the strength of the wall.
The wall could collapse and cause signi
fi
cant damage to your property and/or your
neighbors and could also cause major injuries to people near or in the pool.
REGULAR CLEANING
Keep the wall and resin structure clean. Always clean chemical deposits that may
appear on exterior surfaces of the pool. Cleaning the surfaces of the pool, structure
and wall, is recommended at least once a year with a cleaning product without
bleach.
