Installing new pump

[brasilmom]

Greetings,

we have received the new pump and are now in the installation process. However, we ran into a situation concerning the pipes and we wonder if you have some advice to help us out of this pickle.

The old pump was a Northstar and the pipes coming from the pool are 1-1/2". The new pump supports 2" pipe but we gt a reducer for that. The problem is on the existing pipes and since it is way too difficult to explain, I attaching photos. Certainly we hope not to have to dig the whole thing out and start again....



I hope the photos show. Let me know what questions you may have.

Thanks.

Miriam

Are you saying the threading on the half union doesn't match up, or what?

We cannot use the union from the Northstar on the Pentair pump. And the union from Northstar is glued to the pipe and there is no exposed pipe to put new fittings on. There is only coupling.

Sounds like you're going to have to cut and replace some existing pipe and provide a new half union on that side.

As we inspect the existing lines and valves, etc, we see that there is nothing the is screwed together. all glued. I am afraid to think that we may need to replace the whole thing.

I had a similar problem when I installed a new pump. Fortunately I own a lathe and was able to turn a pvc sleeve, inside coupling, to modify the piping. I don't know if you can buy something like that or perhaps you know someone who can make one for you.
