Fortunately I was in my backyard when this happened. Heard a pop, then noticed a geyser coming out of my pool equipment area. I had 4-5" of water around the enclosure before I could hit the circuit breakers. The top closure dome with pressure guage of the 24" Hayward sand filter had blown off. I found the dome and O ring close by. Inspected the filter, no cracks, no missing chunks out of the filter, just a blown closure dome. I reinstalled the dome and locking bracket. I turned the filter pump on and no runs, no drips and no errors. However the pressure was reading about 5-6 psi higher than it typically was. I usually backwash when the pressure is near 25-26 psi. So, backflushed, waited for clear water, and put the filter back in service. Backwash did not change the guage reading of 25-26 psi. Typical guage reading with clean filter is 20 psi with a high end of 31 psi. Now it appears the typical running psi is 25-26 psi.
I believe the two screws that hold the locking bracket for the dome and filter vibrated loose and the pressure blew it off. It has been 4 days and no runs, no drips, no errors.
Does anyone have ideas about the pressure now being 5-6 psi higher and what else could have caused the top to blow off and cause no damage?
Thank you for your time in this matter.
