It's Not an Ice Rink: Winterizing Your Inground Pool

As winter's approach turns our thoughts toward hot chocolate and snowmen, the Cosmopolitan Hotel in Las Vegas is converting its Boulevard pool into an ice rink! However, that's probably not in the cards for the average homeowner with a cold, idle pool. And while you won't need a Zamboni this fall, you will need to winterize your unused swimming pool. Here's how.

The easy way

Of course, the easiest way is to simply contact a good pool contractor. They open and close hundreds of pools every year, so it's easy for them - and even easier for you. Just get your estimates, choose your contractor and write a check.

The harder way

For DIY-die-hards, here's a checklist. Understand that the pros have excellent reasons for closing pools in exactly this way, so you'll want to follow it closely.

  • Get out your cover, plugs for the skimmers and return jets and your winterizing chemicals. You will also need an air compressor or a powerful shop vac.
  • Backwash the filter thoroughly. Drain DE filter tanks, leaving the backwash valve open. Unplug the sand filter's drain plug and leave it off. Blow out the multiport valve if it's wet.
  • Disconnect your pump and filter and totally drain the pump of water. Remove any drain plugs from the pump.
  • Drain the heater and dry it with a compressor or shop vac.
  • Dain or blow all water from your pipes and fittings.
  • Remove all return jet fittings and skimmer baskets.
  • Blow out all return jet pipes using an air compressor or shop vac until air bubbles become visible from the return jets in the pool. Put a plug in the fitting under the water when you see the bubbles blowing at full force.
  • Blow out all skimmer (suction side) pipes. Put a Gizmo-type screw in the skimmer plug when bubbles become visible. Put PTFE tape on the Gizmo threads before installing. This insures a tight seal.
  • If you have a slide, an auto vac system or a waterfall, you will have to drain and blow out those pipes too.
  • Blow out main drain line (if any). When you see bubbles coming out of the drain, plug the pipe on your end or close the gate valve. This causes an "air lock" in the line and no more water should enter the pipe from the pool side.
  • Put duct tape on all exposed pipes to prevent anything from getting into them.
  • Remove rope and floats.Remove dive board and ladders.
  • Mix any granular winterizing chemicals in a bucket so that they are totally dissolved. Dump mixture into the pool. Add liquid chemicals to pool.
  • Test the pool for pH and total alkalinity. Adjust to normal levels. Make sure one of your winterizing chemicals is a "shock" product.
  • Drop your water below the tile to prevent staining.
  • Place the cover on the pool. Use floats to keep it from sagging into the water.

Winterizing kits

Winterizing your pool properly prevents icky surprises in the spring – the staining and smell of algae growth. A big part of algae prevention is a combination of winterizing chemicals administered when you close your pool. Winterizing kits are premixed and formulated for different pool sizes. They eliminate guesswork, mixing and measuring. Powerful winter pool "shock" kills micro-contaminants, algae and pathogens.
