Richard J Kinch fired this volley in
:

So is threading PVC pipe an unnatural abomination like the top
industry experts at Home Depot, in their orange aprons, assert? Or
just not often worth the labor versus a glued fitting?


Richard, it is "an obama-nation" because it condemns the pressure rating
of the pipe. In your instance, the fittings aren't probably under more
than 15-20psi, so it might be acceptable.

However, unless there's an ell just downwind of the pump, why not whack
off the pipe shorter than necesary, and apply a "repair union" to join
the main line to the nipple section.

Repair unions use rubber compression grommets to seal around the pipe,
and permit the user to slide one or the other end back and forth to
shorten or lengthen the section as necessary for fit-ups.

This would not only solve your existing problem, but mitigate the
difficulties of changing the pump in the future.
