Pool Series & Spa Series Winterization
6. Water MUST be removed from the water quality system plumbing lines. Usually, simply loosening all union collars is
sufficient to drain the system. Using a compressor or wet/dry vacuum may be necessary when gravity draining the
lines will not suffice. Make sure to focus on any low points in the plumbing system; this is where water will collect.
If you have a secondary suction line (described in section 2 above) there will be a 2lb. check valve in place that will
not open to release the water in the pipe without some suction - use wet/dry vacuum. If the water quality system is
equipped with an upgraded pump (most common for remote water quality systems, gas heaters, EZ50), remove the
two drain plugs in the pump housing to remove the water. If the pool is equipped with a filter tank, remove the plug
at the bottom of the tank to drain the water.
7. If the pool has a gas heater, water MUST be removed from the heat exchanger. All heaters come equipped with a
winter drainage accommodation attached to the heat exchanger. These are generally threaded into the exchanger at
its lowest point and can either be removed or opened completely. In certain model heaters, the pressure switch must
be disconnected from its copper tube. Turn off gas to the unit and turn the power toggle switch to the "off" position.
8. Add a non-chlorine winter chemical kit to pool water. Kits vary in many ways. The most important characteristic you
should look for is that the kit has a "non-chlorine" floater that will slowly disperse the contents over the course of
the winter. Generally speaking, Endless Pools tend to be much smaller than what the industry would consider a small
pool, so usually the kit labeled for the smallest gallonage will suffice. Additional chemicals such as algaecide stain and
scale control, and others may be included with this kit, none of which will damage the equipment but may not be
necessary. Winterization kits can be purchased through Endless Pools Customer Service.
9. If outdoors, place a fully inflated "exercise ball" in the pool to provide support for the cover while the water level is
lowered for the winter. These can be sourced at your local sporting goods store. Close the retractable security over
the exercise ball. Place cover pump on top and plug into outlet (if outdoors). Be sure that the discharge hose from
the cover pump drains the water away from the pool area. It is a good idea to periodically check the function of the
pump and outlet over the course of the winter.
10. If a bi-fold cover is installed, snow MUST be monitored and removed from the top of the cover to prevent damage.
11. If you do not have an ASTM rated cover or bifold cover, you must consider safety when covering the pool. Tarps tend
to work the best but can be dangerous if not supported underneath. A platform comprised of plywood and lumber is
recommended in these circumstances to support the tarp.
12. To construct a winter cover:
A. Lay 2x4's on edge across the width of the pool. Space them 16" apart on center.
B. Create a pitch to the cover by laying a 2x4 along one long side of the pool on top of the 2x4's that are
spaced every 16."
C. Cover these 2x4's with plywood and cover the plywood with a tarp.
