How to Backwash a Sand Filter

1. Check your water level to make sure it is up to par. If not, add water up to the required level. Once your water level is accurate, shut off your pool pump. This is a good time to clean out your pump’s basket and skimmer baskets.

2. Turn the valve on your filter to the “backwash” mode.

3. Turn your pool pump back on and watch as all the dirty water gets pumped out of your pool. When it is finished, the water will begin to run clear. During the pumping process, keep your eyes open for possible kinks in the hose and watch your pressure gauge to make sure backpressure doesn’t build up. If you detect any problems, shut your pump off immediately.

4. When your water begins to run clear, turn off the pump.

5. Turn the valve on your filter to “rinse” or “bypass,” depending on the type of filter you have. Turn your pump back on and run the rinse cycle for just a few seconds before turning it off again.

6. Turn off the pump and reset to the “filter” setting. Turn your pump back on and check your pressure gauge. Numbers should be back to normal, indicating your backwash cycle was successful.

A clean pool is a happy pool and a safe environment for your family. With regular maintenance on your pool filter, you will go far in maintaining your backyard watering hole throughout the summer season.
