Questions about replacing booster pump from pentair LA01N to puritech uniboost

[ndnchapathi69]

I just bought a new puritech uniboost. My existing setup has the hard pipes with an inlet connection of .75 in size and outlet of 1.5in. size. It looks like the quick connections the new pump are size 1.5in. The current setup looks like the .75 in pipe connects to a 1.5 in. pipe via a reducer. I'm wondering if I could just remove that reducer, and fasten my quick connects directely to the 1.5in pipe.
One more question, for replacing the outlet connection via a hose, do i just use a pipe cutter to remove the entire hard pipe and use the quick connects on both ends as well?

It appears that the supply pipe to the booster pump can be unthreaded from the pool return line after it is cut. If not, a 3/4" FIP adapter can be glued to the 3/4" pipe. Use two hose adapters for that connection.

The output-to-cleaner line can be cut, a 1.5" coupler glued onto it, a 1.5" X .75" FIP reducer glued into that, and then the other two hose adapters used to connect the pump.

Thanks for the quick reply @1poolman1 I just realized do you recommend using the flex hose? Or sticking with the hard plumbing that was originally in place?

I always use the hose. There is enough vibration in a booster pump to cause leaks in a hard-piped setup. That's why most all booster pumps come with hoses.

Awesome, last question, if I do end up using the couple and reducer, do you have a recommendation on adhesive that I should use?

Home Depot; Christy's Red Hot Blue or Oatey Wet or Dry are both very good. Be sure to sand the paint off the pipe or use primer to remove it.

@1poolman1 , I started the project today, but had a delay because I needed a longer flexible conduit. I already cut off the pipe connections to the booster pump, is it ok to leave the ends exposed over night and finish it up tomorrow? I have turned off the breaker to the booster pump and the system

That glue kit is good stuff. No problem finishing today.
