Backwash commercial pool without multiport valve
How to backwash a commercial (public) pool with no multi-port valve ?
Hi Everyone,
I’m familiar with multi-port valves and basically turning it to backwash. This pool doesn’t have that. It is really a sand filter.I can take pics tomorrow & post if you think that would be helpful.
I’ve tried turning off the filter, and turning the “open/close” valves in the opposite directions, then turned the filter back on… didn’t work.
Help!?
