Why is my pool pump leaking from the top?
Pump Lid The pump lid can leak water and does need replacing sometimes as it is in the weather elements or can crack. If it is leaking water when the pump is off, the pool pump is leaking and you need a replacement lid. The pump lid O-ring needs to be tight and have lubrication in order to make a seal.
What causes a pump to leak?
Dry running A pump seal normally needs fluids to lubricate the materials around shaft. The seal will burn or melt and become damaged, which causes fluid leakage due to the pressure. Even a few seconds of dry running can cause heat cracks or blisters, which leads to a leaking pump shaft seal.
What causes a leak from the top of a pump?
There should be an o-ring somewhere under that nut, that seals between the pipe and the pump body. O-ring damage is the most common cause of a leak in that situation. Alternatively, zea3 might be right and they used some kind of sealant instead, which will be more of a challenge to replace.
How can I fix leak on top of my water pump?
You will need to cut the pvc just above the current fitting coming out of the pump and remove the old fitting from the pump. Use pipe dope to seal the threaded end and use pvc glue to attach the slip end to the existing plumbing. You may also need a connector and some additional pipe to complete the repair.
Is it possible for a pool pump to leak?

What does it mean when your air pump is losing Prime?
Losing prime – If the pump runs dry after manually priming the pump with a hose, , it could be a sign of a more severe air leak. Depending on the location of the leak, the problem could be intermittent, only affecting your pump when a diverter valve is turned to a certain setting.

How can I tell if my pool pump is leaking?
A leaking pump seal can be verified by getting down on all fours (with your reading glasses!) and looking closely to see water dripping down the backside of the seal plate, as shown below. Be careful that the leak is not actually a loose clamp band, or water dripping from the pump outlet fitting, running down and dripping off of the bottom.
How does a pool pump prevent water from leaking?
Every pool pump has a mechanical shaft seal, which prevents water from leaking along the motor shaft, behind the impeller. When the shaft seal fails, it allows water to run down the backside of the seal plate, through the hole where the motor shaft slides through.
