Hi All,
I'm Installing a new pump and the PB didn't leave me any room to replumb. The valve only has 1/2 inch of free pipe before there is an elbow, which needs to be cut off for the new pump. I'm curious if it's possible to separate the PVC from the valve and start new or if the only way to do it is to replace the entire valve assembly. I don't want to do that though as it will be a TON more work.
Thanks for any advice.
Joe
Joe what you want is a 'pipe extender'. It looks ~ like a vac hose end - the smaller part can be glued inside the pvs pipe and the larger side isa the same outer diameter as a peice of pvc pipe. All you need to do is cut off the offending fitting, flush with the fitting and glue one of these into the pipe, then add whatever other fitting you want. If you need a little more info on this, just ask. :)
Sounds good but does it significantly reduce flow?
Joe, you're right that you'll be restricting the line some, but the amount is small. I use them when the cost, to the homeowner, for a whole new valve(s) is gonig to be too much for them. In my experience the restriction has a negligable effect on the system's performance.
Thanks for the reply. I am not moving huge amounts of water either. I have a Pentair Whisperlo 3/4hp which using an average of 50ft of head only flows about 70gpm. The valve draws from two 2" pipes (skimmer/main drain) and outputs to one 2" pipe that leads to the pump/filter which is an FNS PLus.
Given that info still the best approach?
So he used glue in valves? Jerk! I'm assuming you mean a ball valve, not the filter's 6 way valve.
I would bite the bullet and replace the ball valve with one with threads on the inside. Then you glue a threaded nipple onto fresh PVC and do what you need. They also sell double-male fittings, both long and short in 1.5" lengths. That means it's already threaded at both ends and you don't have to make your own.
You're right, it's a Jandy ball valve. Lots of work to replace it though since it connects to another ball valve:( .
I was looking at the valve again and if I cut very close to the current elbow I would have about 11/16" of free straight pipe coming from the valve. Is that enough to get a decent seal?
Thanks,
Joe
Yes on the seal. Not ideal but it will be fine if you make a good joint.

Awesome, that saves me a lot of work. I was looking at the valve today and wondering if I could get a larger pipe that will go on the outside of the valve and then reduce later.......

Joe, the Jandy valves are made to accept two sizes of schedule 40 PVC pipe, one inside and one outside, e.g. 1.5" inside and 2" outside or 2" inside and 2.5" outside. So, you can use the next larger pipe size to connect to the valve and reduce back to the original size.
I wanted to hear that! thanks a ton!!!!
