If you can’t use your pool during winter months, protect your investments and shut down the pool completely. Closing your pool properly makes next season’s start up easy and avoids time-consuming clean up and costly repairs. **Scroll to the bottom of this post for recommendations on just a partial close–since some of us prefer not to deal with the slimy mess that can end up on your winter cover…


1) Bring a water sample to ENGLISH & LEPAGE to find out what is needed to balance your water and insure there are no irregularities.

    a) Adjust the alkalinity to 80-150 ppm.

    b) Adjust pH to 7.2-7.6

   c) Adjust calcium hardness to 150-280 ppm

   d) Ensure sanitizer is at correct level (A green pool will need to be cleared before winterizing)

2) Physically clean the pool. Brush the sides down and vacuum the bottom.  Empty out the skimmer basket(s) and the pump’s hair trap.

3) A shock treatment (HiberShock or Smartshock) is necessary to oxidize any disolved organic material that physical cleaning and filtration could not remove. 

4) Add METALfree directly to pool.

5) Add Pool Magic+PHOSfree through the skimmer with pump on. **Run pump and filter for 24 hours before continuing with next step.

6) Partially drain the pool to about 3-4″ below the skimmer.  Drain/blowout all lines and plug outlets.  Unscrew and remove directional ball from center and each outlet and plug with winterizing plug.  Remove both baskets- skimmer and pump.

7) Install cover over your pool and tie-down or secure it with water bags around the full perimeter to prevent debris and wind from going under the cover.  This should also help to prevent wind damage to your winter cover.


1) Drain the sand filter by opening all plugs, (as well as the two plugs on the pump) and turn the sand filter handle to winterize to aid drainage. Make sure to store plugs in a safe place-as with the pump and skimmer baskets.

2) Remove pressure guages and store inside.

3) Leave all gate valves three-quarters open (except in basement installations).

WINTERIZING YOUR HEATER– Drain and evacuate water from interior lines, refill lines with appropriate anti-freeze.

PARTIAL WINTER CLOSING Some people prefer not to completely shut down their pool. In this case you must keep pool balanced (alka, pH and calcium) and the filtration system is kept running, even if only a few hours a day. In the event of temperatures dropping below freezing, the filtration system should be kept on full time to prevent the pipes from freezing.

Exercise and Relaxation « Pool and Spa 411

Try standing toe raises or pushes against the sides to exercise calf muscles, or tightening and relaxing the thighs. Use the water’s resistance, or add resistance with your hands and push your knees apart and back together again. Make fists and squeeze or clasp your hands in front of you and squeeze your elbows together. After soaking for a few minutes, blood vessels dilate, lowering blood pressure.

Note that when you push down on the valve handle, water will pour out of the backwash port.If flushing the valve out does not resolve the problem, then you will need to remove the valve cover and visually inspect the diverter gasket for debris or damage.
