Product Description

Pool Pump Union 1.5" Male x 1.5" Socket

This pump union is used on Hayward Super Pumps, Max Flo Pumps and Power Flo Pumps. The 1-1/2" male union threads screw into the female threads of the pump ports

Unions will really make your life easier if you need to do any maintenance on your pump as you simply unscrew the union to remove your pump from your plumbing. The alternative without unions is to cut your plumbing to remove the pump and then when the pump needs to go back into place you have to re-plumb and glue. Unions are a necessity if you will be removing your pump from your plumbing during the winter.

Union Benefits

  • Easy servicing of pump
  • No cutting or replumbing of pipe for servicing
  • Great for removing pump in winter
  • Quick disconnect

I have a leaky union on an inlet of a Compupool Clorinator. (Salt System). It is fairly new, and everything looks fine, but I cannot get it to stop leaking What should I do?

Hello, McArthur. I best recommend checking the O-Ring of the Union that is leaking. You should also inspect the Union and/or the Collar for any possible cracks. Click here to view the Schematics and parts available for replacement.

I have a Union on the intake side of the salt chlorinator and I replaced the "O" ring and it still leaks. What is next step? Should I replace the union its self? Or what?

Hi, Replacing the union will be the next step in trying to stop the leak.
