My PVC sprinkler system has a T joint at a certain point. Water has begin to leak out of one of the ends of the T joint. There are no cracks in the pipe, it just leaks out of the T joint over the pipe going into the joint. I tried putting some PVC glue/cement around that joint but the water still is breaking through. Is there any way I can seal off this leak without replacing the T joint which would mean cutting apart three different pipe lines? Is there some kind of combination of glue / cement and a certain tape that will keep the joint from leaking? Thanks.
