Backwash Better

Most people backwash too long and too often, which can reduce filter effectiveness. Backwash only when indicated by a change in pressure (once every 3-4 months is usually enough for a residential pool), and only for as long as it takes for the water in the sight glass to run clear.

If your pressure reading is still high -- 8 to 10 pounds over the "clean" pressure, your filter needs to be cleaned. Sand filters need cleaning or replacing every 5 years.

It is illegal to discharge swimming pool backwash water into gutters or storm drains. It’s usually safe to discharge pool water onto the landscape as long as it doesn’t run off your property and different areas are watered on rotation to avoid a build-up of salt.

Refill Right

Spring and Fall are the best times to refill your pool. Refilling then won’t put a strain on the water system or affect your wastewater average, which is calculated between November and March. Ask your plumber about installing a submeter to monitor water use.

Topping Off

When topping off, use a hose timer to avoid overfilling. Add a few inches as needed on your scheduled watering day to maintain constant water levels. Auto-fill devices can malfuntion and add water unnecessarily. Using a hose makes it easier to tell if a leak develops or the pool level changes dramatically.

Reduce Water Loss

Surround your pool with shrubs or fences and turn off waterfalls or fountains to cut water loss from wind evaporation. During the winter, safety covers can keep out debris, while lightweight "bubble" covers are suitable for spring and fall.

Save Energy

Use a timer to manage daily operation of fountains, waterfalls and circulation or pool cleaner pumps. Reduce filtration time to six hours per day, and make sure to run the cleaner only when the filter is running.

Take Care of Your Pool

Maintain proper chemical levels and adequate circulation time. You’ll have safer, cleaner water and avoid the need to drain the pool as often.

Delay Draining

Depending on location, maintenance and use, a pool can go up to three years between drainings. In some cases, a partial drainage is all that’s needed -- ask a professional what’s appropriate for your pool. Spa water should be replaced every three months, depending on use. Pool and spa water can be discharged into the storm drain if it does not contain algae or other debris, is free of chlorine and other pool chemicals, and has a pH level between 6.0 and 10.5.
