Thanks, RLP. I meant to come back and update this thread last week, but that's exactly what I did - used 1-1/2" PVC and used the inner threads for the connection to the pump. Now to see if the place I bought the new Pentair hose from will take it back...

Friends, I just had to replace my old Pentair #340210 1.5HP pump (see this thread if interested) connected to my Sand Dollar SD40 sand filter. Thankfully, the inlet plumbing and base alignment is perfect and needs no adjustments (sigh of relief!!) Unfortunately, the 2-1/2" OD pump outlet has...

I did find some replacement motors, but as 1poolman1 said, the cost was right about the same as a new matched pump/motor set. I decided to go that route, with a standard Doheny 1.5 HP model. Hopefully it connects well and easily - but I remain a little skeptical!

Thanks, Zea3. Are you pretty sure it's the motor and not the pump?

Hopefully the link I provided works fine. Does anybody know if Pentair has released a newer motor/pump that is equivalent? Or more likely, it's a whole new pump/filter/base design that's altogether different, right? Is there any way to determine if a new/different pump-motor would fit easily?

Thank You, and I'm sorry about the short video - I was trying to make the video smaller so it could be uploaded, and then I found out that MP4 wasn't even a supported format. Here's a slightly longer video, and I edited the link in the original post to point to this one as well.

Friends, this motor/pump came with my SD40 filter 7 years ago, and I replaced the motor/pump 4 years ago after the first one was flooded (that's a long story.) It's a single speed pump and has been sounding a tiny bit noisy for the past 1-2 years, and has a very slight leak from the pump some...

That would have been perfect for my original installation! I have a standard 2" union after up-sizing to 2" PVC, which connects to my SWG section of pipe. Since I don't really have time to wait to get one of these, I am going to use the same configuration that I originally had. So helpful to...

OK, so to follow up on this, I have done a little more exploration and it turns out that I missed something REALLY obvious. The PVC fitting was actually screwed in to the inside of the ABS outlet from the SD-40 filter top. So I could simply unscrew it (although difficult because there wasn't...

Thanks so much, everyone!! So the union kit has a 2" PVC joint that I can tap into? As for removing the current PVC, is it OK to cement PVC inside ABS plastic? Anything special I should be aware of for that scenario?

It's been a long time since I posted. A few years back, I cemented a 1.5" to 2" PVC pipe adapter inside this ABS filter outlet on my Sand Dollar filter for my AGP. There's a union that connects to my salt water chlorinator after this. Today, it broke off (I'll spare you the details). It...
