I'm not sure if anyone else has had his problem, but the petcock at the bottom of my radiator keeps dripping and I can't get it to stop. It had a little dirt in it from some dirty water, but I cleaned it out and it has a steady flow, but it still has a small drip. I replaced it with a new one a while ago but now I am having the same problem. Does anyone have any suggestions on how to stop the stupid little petcock from dripping?

Alex -- Disassemble it and use Time Saver or fine valve-grinding compound on the mating surfaces.

Mike, thanks for the info, I will give it a try.

Make sure it is not dripping from around the threaded part---they will fool you sometimes. (Experience talking:-)

I use a little "Gasket Goo" on the tapered thread when I put mine back in to seal it.

Try using a little 'inward' pressure while turning the valve. The little springs don't always keep enough pressure on the plugs of plug valves.
