Drained my pool to clean it up and may as well fix a long-time leak in a
Jandy valve that is very hard to get to.
Here's a picture of the pumps with the dozen Jandy valves scattered about:
And, here's the problem Jandy valve:
Looking at how extremely tightly packed the pipes and valves are, I
wonder if anyone can repair anything on a pool. Do they normally pack
them in this tightly (there was plenty of room to spread it out!)
How can I fix this?

I don't know yet what's wrong other than it's leaking.
The 'reason' it started leaking is a mistake of mine. I turned the pool
on, after the winter shutdown, and I FORGOT to turn all the valves on.
So, the cleaner pump was pushing water into this valve overnight until it
finally overheated the pipes and blew a geyser 20 feet into the air.
I replaced the pump and the pipes - but I didn't notice the Jandy valve
(which is the return to the pool) leaking until I powered it all up again.
So, I see I'm looking for one of two problems:
1. Hopefully the housing has not cracked - because not only will I need
to replace the entire valve - but it's almost impossible to even get my
hand in there to do any work so it will be a bear!
2. Hopefully just a gasket has blown. In that case, I still will have a
bear of a time opening it up (screws on top) because it's so inaccessible
(why they build pools this way confounds me) ...
Thanks for the advice. I hope it's just an o-ring!
I also hope I can fine a replacement o-ring!
The screws on the cover come off and they are pretty easy to fix.
This one may not be the right one but just do a image search for the
right one: "jandy valve blow up". I think they are all basically the
same. The pool store should have all the parts.
Yeah, that is tight. One think I noticed it the exposure. I'd build a
*well ventilated* covering for it. The sun and elements are going to
cost you down the road. Don't build anything tight around the heater
though. I'd make a small shed like structure. Or a "lean-to".
Yeah. Not only are the dozen valves, dozen pipes and three motors, one
filter and one heater plus solar all jammed together, but many of the
valves are less than an inch from each other ... so close that I have to
constantly remove the jandy handles just to turn them on or off.
Who builds pools this way? (Answer: Lifetime pools ... so I should yell
at them ... but I was just wondering if this was typical).
I mean they had PLENTY of room! They did not have to jam it all in there.
The pipes can only be accessed from the direction of all the equipment
because there is a retaining wall an inch behind them. I mean couldn't
they have put the pipes a foot away from the retaining wall? Jeezus.
It drives me crazy every time I have to do anything around these things.
Oh well, I guess it makes the lean-to enclosure smaller! :)
Yeah, but you don't want to make it even more difficult to get to.
The good thing is it looks like fairly new equipment. My pool equipment
is from the early 80's and everything but the sand filter, pipes and the
valve housings have been replaced. Now it needs to be re-plastered.
Pools can be real money pits.
You're always helpful so I trust your opinion.
It 'is' a real mess! This picture shows how hard it is to get to:
Today, it took about an hour just to get the screws off the top.
I first took apart a junk Jandy valve to see what's inside. It's pretty
simple. It has only six parts.
1) The lock nut
2) The handle
3) The cover plate
4) The cover-plate o-ring
5) The swinging gate
6) The body
Here's a picture of the junk Jandy valve taken apart:
Then I took apart my Jandy valve in situ. It was a bear. This photo shows
that I think the housing is cracked!
There is only about an inch between the bottom of the Jandy valve and the
ground level. It's a very tight fit, even if I dig.
If I slice the Jandy valve off at the bottom, how much pipe do I need to
hook another pipe to it so that I can then hook a new Jandy valve to that
The depth of the socket on any of these fittings is
about 1.5". If you had to, you could get away with
the pipe not fully seating. If you got 1" inside it that
should be enough to hold it. The pressures are
only 20psi or so, and being outside, the consequences
of failure probably aren't that great.
Aren't Ferncos only rated for waste system use,
ie not pressure rated? Still if nothing else works and
since it's a pool might be OK. But if he can get
the Fernco in there I would think he could also get
a PVC repair coupling in.
For OP, for repairs like this a repair coupling is
often key. It's like a regular PVC coupling,
except a regular coupling has a ridge inside at
the midpoint. That serves as a stop of the two
pieces of pipe where they meet. With a repair
coupling there is no stop so you can slide it all
the way onto a piece of pipe, butt another piece
up to it, then slide it back over where they meet.
Interesting. Yes, a flexible shaft would have been perfect because I
couldn't get a straight shot on most of the screws and there is a pipe
right in front (less than the length of a stubby screwdriver) of the Jandy

I see. Thanks. I generally don't go for the new-fangled tools, assuming
they're all junk compared to the old-style stuff (have they really
invented a 'new tool') but this one would have come in handy when I was
unscrewing in a tight space!
But usually, I find the new-fangled tools a bit too thick, a bit too
wide, a bit too flimsy, and a not robust enough - compared to the basic

Those are "old" tools. I bought one almost 40 years ago and used if
often enough. That one was one-piece, ratcheting, just for slotted
screws When you need it, you're glad you have it.
I don't have any now, including the ones I linked to.
Haven't missed them, but I hardly do anything any more.
Most stuff is engineered now to not require an offset screwdriver on a
"Special" tools are kind of always in there own category in those
terms. But I hear you about the thickness. Those multi-bit offsets
wouldn't get on some of the screws I used my old one on. It could get
into a space half the height the new ones can.
Something like the offsets here, but a little thicker.
But mine was a Craftsman, and cheap to buy.
Looks like they don't sell them anymore.
Just like nailspinners.
Wow. The nice thing about your response is it give me courage to TRY to
open it up to see what's inside.
I have a spare (taken from the dumpster at a pool store yesterday that I
will experiment on first as it can be opened up on my desktop. I might
even be able to re-use parts if I can't get them at the store - but the
housing is useless since it's already cemented into the pipes which were
cut off when it was thrown away).
You'd have to redesign the pool plumbing too.
He's got three pumps but no Polaris pump and can't vacuum.
I think I can see 7 Jandy valves. <????> I have a total of 2 for my
pool and spa. One for the suction and one for return.
I just went out and counted 20 valves, in toto, although 2 were
electrical Compool CVA-24 valves and 1 was unused (the pipe is capped off
for a vacuum that isn't installed) and 1 had no diverter as it just had a
clear viewing window.
I looked some more and the one that's leaking is definitely cracked!
I'm not sure if epoxy would work so I'm going to, sadly, replace it.
Here's a closeup of the inch-long crack necessitating the repair:
