I have a higher than normal psi of 33 on my Pentair FNS Plus 48 filter after cleaning all grids, etc. I noticed one grid was ripped and others have broken ribs with loose particles in the grids. Would this be the culprit of my high psi? I have no DE filtering back in pool and my Caretaker in floor is reading a little low at 15psi.
Reply
Usually torn grids would not lead to higher than normal pressure, but rather DE getting back in the pool and a lack of filter efficiency. Most filters have a breather tube to automatically purge air trapped at the top of the filter. This tube generally run from just under the top dome to the bottom of the tank. The breather tubes of some of the DE filters are integrated in the top manifold assembly and exit out through the discharge line. Air pressure in the top of the filter tank will build up if these breather tubes become clogged. I would suggest checking that first.

I have an old Haywood DE 4800 pool filter. It's going on 18 years old. Each year I've been religious on taking it apart and cleaning it. This year I notice DE leaking back into pool. Based on the age of the filter should I just the replace the filter grids and piece meal it or should I invest in a new filter. I'd hate to replace the grids and come to find out that all the other filter parts begin to fail. Ordering all the replacement parts is more than double a new filter.

When it comes time to replace the grids on your D.E. filter it may have been years. In that time key information like owner’s manuals could have been lost. The unit tag information may have become worn and unreadable, making it difficult to determine the size and type you need. Attached is the How To Guide.

Generally you would replace the grids once there is a tear in the fabric or the plastic on the inside is broken upon visual inspection. You would also be able to tell if you have DE returning into the pool.

At Spring startup, while vacuuming out the pool, the big o-ring between the top and bottom halves of the DE filter (Pentair FNS+4800) blew out of its channel with a big bang and an incredible fountain or water.
Several attempts at cleaning up, replacing with a new o-ring, but it kept happening. I noticed that after backwashing the pool would run ok until I started to vac.
Opened the filter and pulled out the grids and found them coated with clay. This was a weird winter where the usual 1 to 2 feet of snow were replaced with rainstorms that left three to four inches of mud, which had gummed up my filter.
I took the grids apart and thoroughly cleaned them, but it turned out that there was mud on the inside that I could not get out, so I ordered replacement grids, vac'd the pool to waste in order to get the clay out without further filter damage, assembled the grids and thoroughly cleaned everything and put iot all back together, now everything is working.
Three hints:
1. a 5/8" racheting wrench makes it a lot easier to get the band and clamp off and back on and also fits the drain plug. Be sure to watch a video about opening and closing the filter and carefully follow the instructions about hitting all the way around the band with a mallet once for every couple of turns of the bolt in the clamp
2. you need to lubricate the o-ring, like any O-ring. The easiest thing to do is to fill one hand with silicone lube and use the other hand to pull the o-ring through. WRONG this stretches the o-ring. instead, use your fingers to PUSH the o-ring through the lube.
3. it can be a little tricky to correctly position the grids on the bottom support. When done correctly, the backbone of each grid will rest directly on a little circle in the bottom manifold that provides support.

I found DE entering my pool- which meant I had one or more bad filter grids. As it had been awhile since I had replaced any of them, I decided to just order a full new set. Process was simple, just disassemble filter , remove grids ( cleansed the ones I removed to see what shape they were in), decided to go ahead and replace with the whole new set, re assemble grids, reassemble filter, put on new o ring, close unit back up
