PVC Stuck Together

So I have a friend who was dry fitting some PVC into a bulk head and it got stuck...what can I, I mean he, do to get it "unstuck"?

if you are dry fitting that means you did not use glue. in that case all you should have to do is just twist the pipe until it moves and then pull it out.

It might help to take the bulkhead out. Even if it is REALLY stuck on there a little jiggling it back and forth will usually do it.

DEFINITELY take the bulkhead out - especially if it is in acrylic. I believe that there is an almost indistinguishable taper on the surfaces of slip-fit PVC pipe and that is why they "lock" together - even without glue. I have been in that same situation and it took a surprising amount of force to get the fittings apart. It would be easy to break something if the bulkhead was left in place.
You might also consider using some soapy water (WD-40 if you take care to completely clean it) and allow it to seep into the joint as you wiggle it side-to-side. It can be frustrating, but be patient. Good Luck!

plumbing PVC components do indeed have tapered joints. its due to the manufacturing process. if the joints weren't tapered, they'd never be able to get the castings out of the molds.

Thanks for the advice. It is dry fitted but is not in the tank. It is really stuck together, no ammount of force is working. I'll try the warm soapy water.

I wouldn't use wd40. hold the pipe and tap on the fitting with a hammer. work your way around and it should pop right off

Not only that, but the taper is designed to create a tight fit during the solvent weld. Sockets could be made without a taper, but they would not work as well

A little soapy water will do the trick. Please do remove the bulkhead from the tank so that you don't break something.

two pairs of wrenches, rags around the bulkhead and pipe, best if you can do it yourself but get a pair of helping hands if you need them, slowly twist, if it doesn't work the first time let some soapy water seep into the seam and wait a few minutes and try turning a little at a time.

It sounds like you might have a bad cut on the pipe too. If that's the case don't use that fitting...it might have a gash in it and could leak.
it's not worth saving the 30 cents IMO.
