[quote=Hobie]Since you are going to replace the reg, you could sacrifice it until your get the repair. Shut off water and get some JB WELD putty. You mash it between your fingers ( gloves) to mix the epoxy. Remove the pressure screw and coat the threads. Reinstall and it should stop leak. Dry within an hour. ( Im assuming it is leaking at the threads only)[/quote]

It’s a slow drip at the treads so I’ll not worry about it since the plumber will be over tomorrow afternoon. Got to drive back home and get a picture of the whole thing so he can order the right size, the model number isn’t good enough. Thanks for the info on stopping leaks.
