Is it always necessary to remove the pool pump to replace the seal? Your videos seem to show the pump on a bench. I want to replace the seal while leaving the pump installed next to my pool.
No, it is not necessary to remove the pump from the plumbing to replace the shaft seal. We use the workbench because it’s easier to demonstrate the process for the camera. But, once you remove the motor from the pump housing and disconnect the leads to its terminal board, you can also move it to a more convenient workspace.
Hi,
Thank you for the video.
It was excellent
My only problem was that it was very hard to push the seal onto the impeller,
I think i may have created a crack in the outer black part of seal. Bu t I had no choice but to use it.
The old one definitely had a breakage in the part inside the spring.
There was small debris in the impeller and on the other side of the seal.
Any way it is running now and so far not leaking.
Thank you for the video!
Did your impeller stem have this steel cuff on it? If so, that was a piece of the old shaft seal and should be removed before trying to install the new seal. The new seal can’t fit over it.
Thank you for your video. It was very useful and detail-oriented. I have an SP2610x15
pump. I am going to be changing the Shaft seal and gaskets in the motor. It had been
leaking water at the pump housing and motor. I will let you know what happens.
I want to say thank you for this video. It was clear and very helpful as I replaced my pump.
Invaluable information for diy guys.
Thanks again!
Keep up the great work!
Thanks!
Hi there,
I have a Hayward Super Pump SP2610X15 and replaced the shaft seals.
The pump now leaks from the bottom, so I assume I either installed them incorrectly or damaged something.
How can I tell what to do next? Should I try replacing the impeller? the shaft of the impeller wasn’t very pretty, but not sure that matters.
The first thing to do is to open the pump and try to find where the leak is coming from. The stem of the impeller is likely corroded due to the old shaft seal being bad. If I had to bet, the housing gasket or shaft seal is sitting wrong. The stem of the impeller is sheathed by the shaft seal, so it is more of a passenger when it comes to sealing in the water.
First things first, open the pump to try to determine where the leak is coming from. You have to know what you are dealing with before you can fix it. Changing the impeller doesn’t fix a leak. The impeller’s only job is to pull and push water; it doesn’t seal the pump. The shaft seal sheathes the impeller’s stem, so the seal should still be retaining water even if the stem was a little chewed up.
