I replaced the whole inlet screen assembly and still not fully pressurizing. I'm told it can be the accumulator tank has lost pressure or is just old and needs to be replaced. I finally found where it is. The most difficult to reach location you can imagine. It's on the port side, up behind the deck sink and closet. I don't understand why designers thought that was a reasonable location. Anyhow, ordering a new one (approx $40) and gonna try replacing. Will let you know. Thx
