Installed a shallow well pump ( sprinkler ) that has threaded inlet and outlet . After gluing all the pvc pipe together ( after screwing in the threaded inlet and outlet) I discovered a small leak at the outlet side coming from the threaded adapter. Since it's now all glued in place I can't tighten the adapter since it would twist the pipes. Any suggestions on how to stop the leak ? I used plenty of plumbers tape when I threaded the adapters onto the pump and tightened them sufficiently. Any help greatly appreciated .

Buy some couplings....cut the pipe, do it again
Yep, I agree. Nothing less than cutting it out, cinching it down better, and gluing in a coupling is your only option.
Thanks for both your replies but I've already done that, this is my second set of couplings ! I suspect there might be a defect in the threads inside the pump outlet . I don't want to buy another pump. I can't tighten the coupling any more than I have already without cracking something. Thought someone would know a tape, putty, old plumbers trick, etc. that I could try to stop the leak at those threads. Thanks anyway .
How much Teflon are you using? You say”lots”.....well that can be a bad thing. Teflon isn’t meant to stop the threads from leaking. It’s designed to lubricate the threads so you can get them tighter. Threads are tapered so they seal. It only takes a few wraps of Teflon to do the job.
The other issue I have is that I try to never thread plastic into metal and vice versa. There’s something about it that just never works. I try and keep my mouth shut around here because I’m in Canada and guys in the USA post stuff here that I would say I’d never do, yet it works. But out in the field I’ve had many leaks threading plastic into metal. Brass/copper wherever I can.

we use teflon tape (some brands are better than others) and pipe dope on evey threaded connection. Also the teflon needs to be applied in the same direction that the threads tighten
While we are on the topic, why do you crazy Canooks add the letter "U" when you spell flavor?
Because we spell things the right way
