I replaced all my old equipment with new Hayward equipment a week ago. The pool is being broken in now as it was replastered. The water is green with algae and I assume it is clogging the new DE filter as pressure is around 20psi and the flow is nearly non-existent. What are the steps to backwash?
The equipment I have are hayward 4028 DE filter with multi-port valve, and Hayward Ecostar VS pump.
I read somewhere the pump shouldn't be more than 2000 rpm during backflush. When I shut the pump and turn it back on, it goes through the priming startup at 3400 rpm. I have to shut the pump in order to switch the valve to backwash.
Does anyone have experience with these and can outline the exact steps I need to follow?
Also, how much DE do I need to put through the skimmer once done backwashing?
