Look for small crack in strainer housing or missing o-ring on cover , i use a eye dropper of blue dye on outside !! of strainer housing , a quick look at pool return and you'll see where the crack is , dry out housing 1st but superglue has saved many a cracked strainer from replacemnet

*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.

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.

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.
