Why are we talking swimming pool closing to pool owners in Austin, Texas? Because Labor Day, in many areas of the country signify the end of summer and that means many people will be closing their pools for the season.

How to close your swimming pool

Here is what needs to occur during a swimming pool closing and what your Austin, Texas swimming pool service professional will do if he undertakes the task for you:

  1. Three to seven days before you plan to close the pool, adjust your water balances within the following ranges: pH: 7.2 – 7.6; Alkalinity: 80 – 120 ppm; Calcium Hardness: 180 – 220 ppm
  2. Shock the pool with a chlorine shock or a non-chlorine shock of at least one pound per 10,000 gallons (follow package directions). Wait chlorine levels to return to 1.0 – 3.0 ppm before adding any winter algaecide and the pool cover.
  3. Remove accessories including ladders, fittings, skimmer baskets and solar blankets – Store in a safe location for the winter, making certain you don’t coil your pool cleaner hoses too tightly.
  4. Reduce water level – Using either a submersible, or the filter pump, lower the pool level to between 12 and 18 inches below the skimmer for mesh covers and 3 to 6 inches below the tile for solid, floating covers.
  5. Drain — Water must be drained or they will freeze and crack. After draining, remove filters and clean thoroughly. If the filter and pump are small enough you can remove, clean and store indoors. If that isn’t an option, you might want to consider blowing out the remaining air with a shop vacuum.
  6. Lubricate — It’s time to lubricate the pump lid o-rings. If the pool has a slide valve on the filter, lubricate its o-rings as well. Consider lubricating the threads on your gas heater as well.
  7. Thorough cleaning — If the pool has algae or silt you may want to bypass the filter and manually vacuum the dirt from the pool – this will prevent your filter from clogging. Place the multiport filter valve on drain to waste position (usually 2pm, if viewed as a clock face) If you have a push-pull filter valve, or a cartridge type filter there is no easy way to vacuum to waste, except for cutting the pipe coming out of the pump and then reconnecting afterwards. Brush the pool thoroughly. The pool should be as clean and clear as possible before covering.
  8. Winterize  – With inground pools you should blow out the lines from the skimmer, through the equipment and back to the pool. Once you’re done, plug the lines at the pool. If you don’t blow the lines, add Swimming Pool antifreeze to prevent cracking and breakage. Owners of above ground pools usually just need to disconnect the hoses to and from the pump and filter, and plug the wall outlets.
  9. Add algaecide – Don’t add algaecide and shock at the same time. This could result in the chlorine breaking down the algaecide.
  10. Cover it — Your cover should not have holes or gaps where leaves and debris may enter. A mesh safety cover provides the highest protection. Solid pool covers do not offer as much protection and require a siphon to remove rain water or melting snow. Drop in air pillows to help with the expansion of ice inside the pool.
  11. Check it occasionally. Keep an eye on the pool throughout the season and clear off debris and pump off standing water.

If you live in an area of the country — like Texas — where temperatures don’t usually dip into the freezing range, you may be able to use your pool for many more weeks, especially if you use a swimming pool heater.
