Hello TFP command :cool: et al;
I have had the S200 for 20 years various piping change outs but pretty standard . What has happened is the appearance of air in the system and I do not se any leaking water out of the sand canister, valves or fittings. There is a bleeder at the top of the filter ( I hope thats a bleeder) that I have attempted to use to bleed air out of the system. No help is there a way to pressure test these systems ?

Welcome to TFP.

Air in a filter comes from suction side air leaks before the pump input. Once past the pump the plumbing is pressurized and any opening will leak water and not suck in air. Read...
