You have to change d. e. when your pressure starts to climb shortly after you bump the filter.what I found when you first open your pool at the start of the season and have some extra trash and dirt to vacume youwill have to change the d. e. a couple of times.just remember the first charge is 4 scoops and after that you only need 3 scoops since all of the d. e. doesn't come out .I find it helpful to bump the handel several times while you are draining d.e. out of the filter. hope this helps and have a great weekend.

My inground pool filter guage is fairly new and registering 0 even though pool seems to be running fine


if you are sure water is circulating (check to see if water is being sucked into the skimmer suction port or you can open your air relief valve on top of your filter and water squirts out,) then you will know that all works, but if pressure gauge is "0", then replace your pressure gauge.

While vacuming loses suction, sand filter pressure goes high


That increase is due to the filter loading up with debris. Is the pool unusually dirty? If there is a lot of dirt and silt in the pool use the "waste" setting on your backwash valve while vacuuming.
This allows the water to bypass the filter and go directly out the waste line. Keep an eye on your water level because you will be removing water from the pool and may have to add more.

Pump stops suction when I try to vacum pool


1. Something is stopping the seal at the basket
2. The hose going to the filter housing is partially clogged or not sealed
3. If you have a 2nd filter basket before filter housing, clogged/not sealed
4. Filter is clogged and needs to be cleaned, not just dirt, but degreased
5. Leaking pressure valve if one is used

I had a large filter and regular pressure was well above 5 psi, (8 to 10psi) with everything cleaned and running, once vacuum hose was connected it jumped to 14 to 18 psi.

My pressure or psi has droped for some reason its a hayward new 1 hp pump about a year it should be running at about 10 psi I know when the psi rises I need to backwash as I have a had a pool now for about...


Some thoughts.
I have a Hayward pump. The other day my gauge jumped a gear inside and suddenly my pressure went up 5 psi from 15 to 20. After I backwashed, I saw it didn't drop and opened the gauge and saw the problem.
What kind of filter do you have? If you have one with filter cloth, like DE, a torn or damaged filter cloth could cause a drop in pressure.
Is filter flow better or worse than normal?
If flow is lower, there may be something stuck in the hoses, pump suction, impellar, pump discharge or discharge hoses or even filter valve.

These are some areas to check, pretty much in order of likelyhood.

System runs fine until trying to vacuum


Pull the strainer basket out of the pump and reach into the intake of the pump at the bottom of the basin. If any debris gets into this area, the pump will not have great suction. The baskets and pipes etc will appear in good condition, but if the intake is plugged up, this could be your problem.

Pump won't **** when attach the hose


Its very possible that it is not a problem with the pool pump, but a problem with the conncetion to the vacuum hose. If you are losing pressure only when you vacuum, make sure that your connection is secure and you have no holes, cracks, etc. in your line. If you think that there are definate pool pump problems, check for the following problems.

1) Clogged or restricted strainer or suction line

2) Plugged or restricted discharge line of filter (high

discharge gauge reading).

3) Air leak in suction (bubbles issuing from return fittings).

4) Pump operating underspeed (low voltage).

5) Plugged or restricted impeller.

Lose vacuum on pool bottom cleaner


My pool filter runs fine when skimming, but when I attach the droid or manual vacuum the basket has sucked air. Do impellers ware out? Is there a seal between the motor and the impeller that can leak air?
