    How to disconnect booster pump?

    I have a Polaris PB4 booster pump that's not working. I am able to manually rotate the shaft and have replaced the capacitor, but it still only hums when I try to turn it on. I would like to bring it into the shop to get it checked out. Problem is, I'm not sure how to disconnect it. While my main pump is connected with compression fittings, the plumbing that connects to the booster pump is sealed with what I assume to be joint compound.

    I'd appreciate any suggestions on how to proceed.

    Looks like you can leave the plumbing there. Unhook the wiring. Undo the 6 bolts on the impeller housing, pull the whole thing out and take that to the shop.

    @Richard320: Thanks for the suggestion. If I do that, will I need to replace the mechanical seal?

    They'll do it at the shop. They'll fight the impeller off, too, if it's frozen on the shaft.

I think the practices regularly espoused on this forum (especially the BBB method) are outstanding; however my comments will be often oriented towards the goal of getting it done, and getting it done right now!

    Yeah, I'm no math wizard, but I reckon going from 2" to a 1" is cutting that flow in half.
    From what I've read, GPM is where it's at. Keeping the flow going is best.

    These booster pumps are not like regular pumps. The are optimized for high pressure low flow vs. High flow low pressure. Typically they are hooked up with 1" hoses.

    LOL my first pool is the one I am ttaking care of now. I just read a lot and I happen to have the same booster pump. Another thread gave me the education on flow vs pressure - happy to pass it along.
