I noticed today that the filter is not building pressure.
It builds pressure for like a handful of seconds to about almost 15psi and then drops to 0.
Water goes through the skimmer for few seconds and then stops.
This happened once in the past about a week back. After cleaning the restraining basket (near the pump) it just started working. I did the same today. No luck.
I am new to this so I might be missing to provide some basic info. Any info will help.
Should I open up the filter and see whats going on.
I also tried setting the valve to back wash for few seconds. After water drains out for few seconds and I restart the pump, pressure builds up immediately (unlike earlier where it takes a few minutes) but then again pressure drops to zero again.
Thanks in advance,
