I've got a couple of questions that may have a simple answer (before calling someone out). Can anyone help?
I've got two issues with my pool. Not sure if they're connected.
1. When I move my multi-port valve to backwash, rinse, or waste the water runs to waste. This means I can't backwash my pool! I've had the multi-port valve off and there's no obvious damage and the gasket is good. Strange!
2. I've got good return water when on re-circulate, but when I move to filter then the pressure drops significantly and the return is not very powerful. The reading on the pressure gage doesn't go up too much though (from 90+ to just over 100 kpa). As such, I'm also struggling to vacuum the pool as there's simply not enough suction when on filter.
Can anyone shed any light?
I'm sure a backwash would help, but can't do one without spraying my garden with pool water!
Many thanks and Merry Christmas!
