Thanks for the response. I tried re-doing the joint 2-3 times, even using a "pink" (thick) teflon tape and still could not get the joints to
stop leaking - although the leaks were now VERY small. Well, after 3 days of no hot water, time to call in the plumber. He took one look at the
joints and suggested using teflon tape then putting pipe compound on top - and it worked! We have hot water!

Next time I will replace any of the rigid with copper as it is MUCH easier to work with (the rigid in our house is over 40 years old and the
insides of the pipe are badly rusted!

: It may be that you are not tightening it enough - I have seen that happen.

: Also - are you putting the tape on in the same direction that the threads screw in? If you put it on backwards - it will bunch up and come out.

: Are you putting on enough tape? Start at the end of the pipe and "wind" it up every thread (thread by thread). You can add a little tefon paste on top of the tape.
