Leaky PVC Connection

Hi,

I have a leaky connection right at the joint where a PVC pipe is connected to a PVC elbow. I tried to use a rubber coupler with clamps to stop the leak (screwed it so tight I thought I was gonna damage the PVC!). However, the leak is only slowed down! I should also mention there is a little water pressure, but not sure exactly about PSI measurements. How can I stop the leak without permanently sealing the connection? I need to get back in sometimes since my pipes are for a fish tank filter.

Thank you everyone, and try to keep your terms simple and understandable as I am totally new to plumbing.

cut it out and install a new one...

You can install a union so it can be taken apart from time to time...

If there is ANY pressure and it is not sealed, it will leak. There are many ways to glue the joint together and still maintain accessibility, but which one is the best for you depends on many factors that we do not know, such as WHY you need to have the access.

There is no way to repair a leaky PVC joint with a patch. The good news is, it's fairly easy to cut the leaking area out and repair the joint with inexpensive fittings.
