It sounds like a leak or blockage on the suction line. The increased sound is the impeller cavitating with the air/ water mixture.

Can you do a...

The problem now is that pressure goes over 10psi and pressure realief valve opens up and shoos water out. The water suction out from the pool is very...

Hi, All, happy holiday.

I was thinking that as I posted. My skimmer bottom has a 1.5" opening several inches deep where there is suction out the side to the pump and...

I have a Hayward s244t filter (300 lbs). I had replaced the sand earlier in the year and everything was fine up until the day before closing the ppol.

Agreed. It cost me $50.00 Canadian to replace the bearings after 7 years, and the pump sounds brand new now. As long as you haven't let the pump run...

That is very common, but a repair shouldn't result in losing pressure. Could there...

Thanks for the update Dave

Hello,

:thumbup: great one!

Thanks for sharing

Or alternatively a regular valve on each line, allowing you to open the flow in increments and in any combination you need (e.g. vacuum with skimmer...

Need to know filter size/model/diameter and pump size/model/hp etc. to see if they are sized properly. Too little flow will not backwash it properly...

Because the pump is losing prime and you see sand in the basket, I can't think of anything else that would cause that other than a broken pipe. Are...
