Pump diffuser screws won't tighten because the hole threads are stripped

[davidwat]

I'm replacing the diffuser on my pump but I can't get the screws holding the diffuser in place to tighten because the hole threads are stripped. I'm thinking of using an adhesive to keep the screws in place. What underwater adhesive would work best in this situation, or do you have another solution that's worked for you? Thanks.

Were you able to fix this? Did Helicoil work?
thanks, David - Dallas

My husband has had good luck with helicoil in the past. He said it could not hurt to try it.
