Part # 9175-97
Manufacturer Code 200-903
Dimensions 3-3/4" x 2-5/16"
Union, 2" Slip x 2" MPT w/ O-Ring - 200-903
Had a leak at my pump union at end of last season, which I didn't bother with then. Just took it apart and it's a Praher 200-903. Should I replace the entire part (pictured) that goes into the pump, or just the o-rings? If just o-rings, do you carry both?
We would suggest replacing the complete 200-903 this will be the least expensive option by far.

Is it correct that I can leave the part that is cemented onto pool plumbing, or should I replace that, too?

Hi Jason, Could you send a few photos of the part that is cemented onto pool plumbing?

Attached a couple of pics, it's just the collar part of the union that threads onto the piece that is threaded into the pump
Hi Jason, I would first attempt to leave the part that is cemented onto pool plumbing in place and if that works without any leaking then I would leave as is. If you do have any issues by leaving that part cemented in then you will need to cut out and replace, but I would attempt with the old piece in place.
