    Repair leaking PVC elbow in a wall.
    I have discovered a leaking PVC elbow between an upstairs tub and the drain to the downstairs. It is in a very difficult to get to area. Since I can't get to it to cut it out and glue another will a silicone sealant possibly stop the leak? Or is there some other kind of sealant that might work better?

    Repair leaking PVC elbow in a wall.
    Hey Jim,
    Since this is a drainage leak and not one under pressure you can glue it shut.
    First purchase a small can of PVC Primer and a can of PVC Cement.
    Make sure the area's dry and free of moisture. Now prime the area with PVC primer ans slop PVC cement all over the area making sure it gets in the crack in the joint. PVC cement will melt PVC and weld it together, but it must be well primed before. Let it set up overnight before using. Good luck, Tom

    What if the elbow is under pressure? What is a safe repair option other than replacing it?

    "What if the elbow is under pressure? What is a safe repair option other than replacing it?"

    If this waa a leak under pressure you would have no option but to cut it out and replace it. However, this was a drainage complaint. Why are you asking? Regards, Tom

    I have an elbow in a very difficult place that has a crack in it and is under pressure. I was hoping that there was a method by which it could be repaired without having to replace it (welding, melting, sealant, etc.). Thanks for the response, I've got some cutting to do.
