    Brass? Check Valve

    I am not sure about this thing.It is in between the impeller and the mulitport. I want to replace it. I think its corroding and causing metals in the pool...hence my recent issues with brown stains. Any ideas? Just replace with a piece of SCH40

    That looks like a check valve. There aren't all that many other things it could be.

    You might need a check valve in that location, depending on how your plumbing is setup, though that really isn't a very common location for a check valve. Could you describe the rest of your system? Do you have a spa, solar heat, fountain, etc?

    I'd remove it and see how the system performs. If you have an issue, you could always add a PVC check valve in it's place.
