Re: Whatt is considered a "normal" operating range for the filter pressure gauge?
A large pump is going to have high head loss and 46' of head (20 PSI) on the return side is not unreasonable so I would consider that within the normal range for that pump. Also, most DE filters with backwash valves will be on the high side when it comes to head loss.

Re: Whatt is considered a "normal" operating range for the filter pressure gauge?
Mark, the 15% increase in 'clean filter' pressure suggests a problem with the membranes.
Also, on most filters, the pressure gauge is installed downstream of the multiport, and measures only 'back-pressure' from the filter itself + any gear down stream of that. He's starting off with ~60 of head, and going up from there.

Sorry, I guess I misunderstood the post.
