IT WORKS!
Local supplier was out of 2711APR but had 2711DPR. Needed an adaptor: threaded to slip fit.
Now when I cut off the old guy, I found I didn't get the pipes the same height.
I thought this could be an issue for fit and seal. So I tried sanding/filing down
the taller pipe, but I didn't get it much shorter. But it sealed OK.
It was my first time using primer! In my previous jobs I just used glue.
Maybe because they were sections that aren't under pressure all the time.
There is a very slight leak at the threads of the adaptor, which I'm hoping will
seal over time (have seen this happen with teflon tape sometimes). Since it's
way less than the leak on the guy I replaced, I'm pronouncing this job
a success.
Got the wiring back. The previous installation had put some sort of
white goo on the wire ends inside the caps. Got it all over my fingers.
Is this to keep water out?
I'm looking to replace the other three guys next to it. They're all the same
so I think it should go smoothly. The real challenge in this job seems to be
getting two pipes at once to insert into the slip fit. You can't do the
recommended quarter turn. At most you could maybe do it on one of
the pipes before you insert the other? Maybe do it on the pressure side?
