Pool Sand Filters - Its Functions

Many sand pool filters will have what is known as a “Multi-Port Valve”. This valve is an all-in-one valve that makes your pool life a little easier.

If you're not familiar with a Muli-Port Valve please read the following and/or consult your owner's manual concerning your sand pool filter maintenance.

If your swimming pool motor (pump motor) is on and you decide to start turning any valves, that could cause all kinds of swimming pool filter problems. Be sure the filter pump motor is off before turning anything.

Once this part of your swimming pool sand filter maintenance is accomplished your system is ready to rinse. DE pool filters will need to recharge your grids with fresh DE.

Use this setting when:

If you have any questions or are not sure about the Multi-Port Valve or any part of your sand water filters, check with your local pool store and find a qualified pool technician.

Backwash Sand Swimming Pool Filters

For proper care of your inground and above ground sand filter, and to keep your rapid sand filter running at peak performance, you need to backwash your filter when the pool system calls for it.

Here's a normal backwashing cycle for a swimming pool sand filter.

Once again, if you're even the least bit unsure of performing any part of this pool sand filter maintenance, check with a qualified pool technician.

1. A swimming pool sand filter needs backwashing after the pressure has increased about 8-10lbs. higher than the "just backwashed" pressure
2. Raise the water level 1-2" if it's low. Turn the pool filter system OFF and clean the pump basket. Remove any debris and carefully place the basket back into the filter pump housing and reattach the pump lid. Check the gasket or O-ring and if it's torn or broken you'll need to replace it.
4. Roll out your backwash hose, if applicable, and turn the filter control valve to BACKWASH
5. Turn the filter pump back ON and pump out dirty water until the water runs CLEAR, then turn off the pump.
6. Set the control valve to RINSE and turn the pump on for 5-8 seconds. Turn off the pump.

This will get rid of any loose debris or pool filter media that may be in the lines or pool filter system.

7. Turn off pump, turn valve back to FILTER and you're done.

The entire process should take about 5 minutes, a little more for commercial sand filters.

Pool sand filter maintenance is just easy pool maintenance. A swimming pool sand filter is pretty bullet-proof if you take care of it.

Swim and have fun.
