Hi I have a steam heat exchanger that is leaking water from the bundle flange intermittently.Any ideas would be appreciated. Thanks

If it will not tighten up pull it and replace the flange gasket OR if you are real good use gasket rope and lace it. Good luck.

Hi Thank You I'll give that a shot.That was my first thought but where it was'nt leaking constantly ,maybe something else was going on (hole on bundle or bad trap) anyway thanks again.
