How to backwash a pool sand filter.

If you notice that your pool water is not as clear as it used to be, it may be time to clean your filter. If you have a sand filter, this process is called backwashing. In order to check if your filter needs to be backwashed, take a look at the pressure gauge. There will be a place that marks the normal pressure. If the needle is 10 psi over this point, then it is time to clean your filter. 

Over time, the sand in your filter acquires dirt and debris from the pool. These particles make the filtration process less efficient. Backwashing your sand filter will restore the cleaning power of your sand filter so you can get back to swimming in clear water. The process is fairly simple, just follow the steps below:

• Roll out your backwash hose to someplace that the water can go.
• Turn off your pump at the breaker
• Set the multiport valve to backwash
• Turn the pump back on and run until the sight glass is clear
• Turn the pump off at the breaker
• Set the multiport valve to rinse
• Turn the pump on and let it run for about 30 seconds to reset the sand
• Turn the pump off
• Set the multiport to filter
• Turn the pump back on
• Roll up the backwash hose, being sure to get all the water out
