Volute: noun, A spiral scroll, Forming a spiral curve or curves
So I assume the strainer is the pool pump basket, which has an
o-ring at the top under the cover, which I do lube with the
And, the volute is most likely the clamp-on connection where
the impeller does its work; so, yes, I do lube that also with
Thanks for the recommendation (and vocabulary). :)
I dont't know what that measurement is supposed to show.
If the point is that it's not showing 2.5", it's not supposed to.
The 2.5" is the inside diameter of the PIPE that the fitting
mates with. It's not the inside diameter of the fitting which
is going to be a lot larger. The real question is if it fits
snuggly when it's put on, which I hope it does.
He cut it flush with the valve because the coupling is going
OVER the jandy valve. He doesn't want any pipe left outside
the valve. It was either go over it, or get the special tool to
bore out the pipe already glued inside the valve.
I don't see why there should be a lot of play in this. If that
Jandy valve is designed to work with 2.5" fittings, then a 2.5"
fitting should fit over it just like any PVC pipe connection.
If it doesn't and there is a lot of play, then glue isn't the
answer. You might get away with it, but that joint will not
be nearly as strong as it's supposed to be.

I don't know if I have the vocabulary (that Oren has) of describing

When I connect the brand new equipment (for sizing, for example),
I always have a hard time pulling them apart ... they're that tight.
On the other hand, this 2.5" coupling goes on "snug"; but can easily
be pulled back off without much force.
So, it's "snug" but nowhere near as snug as putting a brand new
PVC coupling onto a brand new PVC pipe.
Since that joint is the critical joint, I'll be crossing my fingers
because, if that fails, the only other option (other than draining
the pool) is to bore out the Jandy valves.
On the filter Jandy valve, what *looked* like a pipe was really
a whole bunch of couplings inserted butt-to-butt with the actual
two-inch pipe hiding inside.
On the cleaner Jandy valve, it was just butt-to-butt elbows.
I would have *loved* to have some 2-inch pipe to simply connect
a fitting to - but - there were no "pipes" to be found there!
That was the entire problem, in the first place, which had
prevented a simple repair, over the years (by me or the previous
If it's any consolation, I followed your huckleberry trail almost
exactly - only turning away when the path petered out completely.
In fact, I *did* originally cut the so-called "pipe" very much
closer to the pump, *exactly* as you had advised:
The deviation from your suggested path was determined because
a big boulder blocked the path to huckleberry nirvana, which
in this case, was because there was no 2-inch pipe to be had:
This lack of 2-inch pipe necessitated switching to plan B:
