Plumbing question-Can you remove cemented parts again?

If you used PVC glue there is no way to "undo" the bond. Your best bet is to get a coupler, new valve and a chunk of pipe and replace it. Make sure you test each valve at the store to make sure they work smoothly. Each one is different. Menards are even different than Home Depot's.

Good Luck!

 

no you will have to cut it off and use a union to make up for the lost pipe or just replace from the gate valve down.

ive heard of people heating pvc up to break the bond, but it seems kinda dumb to me considering the cost of pvc and fittings.

 

you do have to cut it and use connectors to apply a new chunk of pipe, what the glue does is melt the 2 pieces together

Ball valves get very expensive up around 2"
Never done it, but can see the advantage if it actually works.

 

To save the ball valve I have cut them out and then popped the pvc out and sanded it down, but it still requires cutting it out of line.
