I’d like to run this by the forum before I call a pool service for help.
Last fall I started having problems with my Hayward Pool Vac Ultra. It used to speed around the pool and do a great job cleaning the entire pool in a few hours. Now it barely crawls and has problems climbing walls and out of the hopper bottom. Coincidentally, I also sprung a small leak in my pump casing. I believe the two are related and I’m pretty sure that the pump casing O-ring or pump seal assembly is the source of the leak. I have not been able to pinpoint the exact location of the leak, but based on where the water is collecting under the pump, it is in the general area of these seals.
The pump is a 1987 ITT Marlow 1-1/2 J75EC10 pump which has worked well since I bought the house 4 years ago. In normal filtering mode, there are a few real small bubbles visible through the strainer cover. It has been like this since I bought the house. When I connect the pool vac to the system, the pump strainer chamber seems to run at about half full and I can see the water pouring into the strainer from the suction line. I don’t know if this is how it always was, but I seem to recall always seeing more air in the strainer when the vac was connected.
Could the pump leak cause the problems with the Vac? (Just realized that I need to see if the pump leaks when the vac is connected. If it leaks, the air is probably not from the source of the leak.) If the leaks are not the source of air, then I probably have a leak in the suction line. Any suggestions for testing the line?
I’ve looked online to see if I could locate a seals kit for the pump, but I have not seen the exact model number or parts breakdown that I have in the manual. My guess is that ITT Marlow is no longer around and the pump probably falls under another manufacturer’s umbrella.
Any suggestions for finding parts for this pump?
Finally, I am not a mechanic, but I know enough about pumps that I think can tear it apart and replace the seals if I can find the parts. Am I mistaken? The O-rings are easy, I’m not sure about the seal assembly.
Thanks in advance!
