You have a hole(s) in one of your panels or the panels are not fasten tightly together on the assembly rod. Take the panels out of the tank and inspect them carefully for holes. Replace the panels with holes in them for best results.

I am not getting a strong, even flow into the pool from the return. What should I do?

clean/replace your filter if its cartridge or the media if its DE or sand. DE and sand arent good forever. check all hoses and skimmer for blocks. also look for holes in the hoses. A small hole will draw air in and throw everything off.

Appears that the silicone sand is being thrown back into the pool from the return jets? I assume something gave out since the filter is old. What part is needed to replace on the EC65 DE Filter?

Is this a DE filter or a sand filter: Check all internal parts of your DE filter for holes or breaks. There is a hose inside that is suppose to eliminate air locks ... it may be submerged. Same applies to sand ... find the broken lateral or air lock preventing hose.

If you have a DE filter and sand is coming into the pool ... there is definitely a hole returning sand that bathers introduced into the pool ...

You are using DE in your DE filter, right??? not sand ... right???

Pentair Quad DE system was installed without multiport valve

This is a DE (Diatomaceous earth) IT doesn't have sand and doesn't backwash. You use the bump handle (with pump off and valves closed and vent open and drain dirty water/earth out) Here is a link to the manual for your filter If isn't the exact model they are all on their web site:

Not filtering correctly

The alge will always work through the filter and eventually cause problems in the filter. What you need to do is kill all the alge so when it's dead and just dirt the filter will collect it A small amount of DE powder in the skimmer will help at this point but be sure the alge is killed off first. You can use a lot ok liquid chloriene to start the process. Depending on how bad it is and how big a pool you have. I will usually start with about six to ten gallons and repete after twelve hours if nessary.

I'm getting DE back in my pool from the 4820 filter

One of two things can cause this. Either the spider gasket is bad or there is a rip or tear in one or more of the filter grids.
(the spider gasket is inside the valve you turn to backwash filter)

Anthony filter system faulters after short while of running

If you have alge in your water it builds up in the filter and stopps it up rite away. You will need to take the filter apart again and hand clean it out again. but you will need to super chlorinate the water and kill all the alge before you start the pump or it will plug again. If you run it like this for any amount of time it will crush the grids, so be sure you kill all the alge.

Pent air pool filter

Buddy is this happening, after the pump turns off or during.. Need more info.. type of filter.. Sometimes the sleeves on the neck area of the panel. Where it mates with the manifold slide down, you will have a small opening. Might be from their.. Could be a hole on one of the panels. Do you have a push/pull valve or a multiport valve (to back wash)
