Question about Pentair "Pentair" In Ground Pool Pump At251001

1 Answer

Why is the pump pulling water but blowing air as well as water in the pool?

We just put a new oring on and it is filling with water but when I plug the vacuum hose in it stops working and when I pull the hose out it still doesn't work

SOURCE: pool pump won't prime

check for air leaks, cover o-ring is common culprit. anything in front of pump can cause this.

SOURCE: pump is not pulling the water from the pool

*Check all of the drain plugs*...You would want to check for air leaks on the suction side of the pump. Make sure that there is water at least 3/4 of the way up in the pump and the valves are in the right position (sometimes turning the skimmer off and just sucking from the main drain can help). Also check to make sure that there is water in the skimmer, and it is not getting sucked dry. Next lubricate the pump lid gasket, and try some silicone around the threaded pipe on the front of the pump. If all this fails you could have some debris stuck in the impeller.

SOURCE: When I turn the suction

sounds like you have alot of air coming from the pool. check the weir in the skimmer to make sure it's not stuck and blocking water from coming in, assuming the water level in the pool is normal.

If you have an auto cleaner, make sure the hoses are not cracked. Use a process of elimination to try and determine where the air is coming from. If you can't find anything obvious, have the line(s) pressure tested.

SOURCE: My pressure gauge is reading 0 when the pump is

1. Make sure multi-port valve if on "filter" (gotta start with the easy answers)
2. Remove the V-clamp holding the pump housing together and start inspection.
3. remove diffuser to gain access to the impeller.
4. check impeller for clogs (very common if around pine trees)
5. If impeller in free of debris, inspect housing o-ring, diffuser o-ring, drain plug o-ring, and shaft seal (if any one of these parts as failed, this pump will not prime and the filter will have no pressure)
6. If all these things check out, then it is possible you have a suction side plumbing clog. (is the skimmer and main drain protected by screens? if so, a clog is very unlikely)

Note: the most common cause of a loss of "prime" on a pump is a failed shaft seal. It is cheap and easy to replce.
You will not want to remove the impeller or do any serious work on this pump unless you have replacement o-rings for the internals. New o-rings and seals is what allows these pumps to work properly.

Hope this helps

Sounds like you're trying to pull water from skimmer and main drain. Soon as the level goes down, it sucks air from skimmer. Turn off skimmer line. If that's not possible, then cut off input side of pump(front pipe) and run new line to pool. Just lay it on top of ground and keep it below top by a couple of feet. This will stop all the **** on the bottom from plugging up the pump.

Pool cleaner starts and then stops working


Check for water flow / water flow restrictions / and water flow blockages.

Many things create water flow reductions: Dirty filters, plugged impellers, packed with debris baskets - both skimmers and at pump, closed to partially closed valves, air suction leaks: worn shaft seal, worn orings at pump lid or pump volute body, low water level, stuck skimmer weir blade/gate in the up position & skimmer empties and air is sucked into the system which may cause the pump to lose prime. This a problem that goes un-noticed and is hard to detect even by some service technicians!

Loss of suction and loosing prime on pump


This can be a number of problems....
Are the filter , and all baskets clean? Is the pump impeller clogged with debri? Is the pool water level high enough for flow?
Is there something stuck in the line, do you have a pool vac if so check it for blockage.
If you think none of the above mentioned are your issue, then the next step is to find the air leak, which most likely is in from of the inlet of the pump, if you get a water hose or container of water, turn on the pump and then pour the water one by one on all the plumbing joints and or valves that are ahead of the pump, of one of them has an air leak the water will fill the air gap and allow the pump to prime and you have found the problem. This can be used on fittings after the pump as well but typically an issue like this is ahead of the pump.
Many times it will be the inlet pipe which is threaded into the pump or the valve ahead of the pump needs new orings.

How do i hook a vaccum up to my model 604 filter pump?


You should take your vacuum hose and plug it into the hole in the bottom of one of the skimmers. Fill the hose with water first or your pump will loose suction. I fill my hose by putting the head of the vacuum in the pool. Take the other end and hold it over a pool's discharge port (where the water comes back to the pool from the pump. When the air bubbles stop, put your hand over the end of the hose and move it to the skimmer and connect it.

That work for you?

My Kreepy Krauly is working at half speed, any ideas? I've checked the tubing, no visible leaks, flapper works. Seems to pull air into the filter even after tubing is full of water. Both baskets clean.


Are you using a skimmer plate with the regulator valve or is connected direct to wall? Do you have a valve near pump that allows you to select skimmer or main drain or other input port? If so, select only skimmer. What is the pressure on your filter? Filter may need to be backwashed.

Check the strainer housing on the front of the pump for a worn out oring. If you see water swirling around the in basket, it is a good indicator that air is making it's way in past the o-ring killing the waterflow. (the prime) Replace the oring. Make sure you lube the oring with a non-petrolum silicon grease.
