Trying to get my pool in order and I am getting a enough sand blown back in the pool to make it very noticeable on the bottom of the pool. It is a Hayward sand filter and was just installed last July. Could it be a broken lateral or more? Or could there be a simpler explaination do to my backwashing and rinsing? Getting ticked off by this situation. I like having a clean pool!
When I backwash I turn the pump off, switch multiport valve to backwash and turn the pump back on. When sight glass in clear I turn the pump off, switch to rinse and run rinse for about 30 sec to a minute. Is this right, or am I missing something that would result in the sand getting put back into pool?
Also, if you think it is a lateral, do I have any kind of warranty that I could get work done, or just something I do myself? Thanks for the help!!!
