Forum Title: Replacing a boiler drain valve with a leaky handle
Our washing machine supply uses 1/4-turn boiler drain valves as its shutoffs, which we use every time we use the machine. They are approximately 5 years old. Recently the hot water valve started leaking right underneath the red handle (picture attached). It's kind of a slow drip, about once every 10-12 seconds. I tried tightening the hex head screw holding the handle in place, but it doesn't seem to have any effect, and I don't want to force it and break the pipe. I have a new Mueller boiler drain (picture attached) I picked up at the local big box store. I believe I simply need to: 1) shutoff the main 2) remove the braided hose from the washing machine end 3) remove the old valve with a wrench, using vice grips to hold the female end 4) apply Teflon tape to the inlet threads on the new valve, clockwise 5) insert and tighten the new valve, finishing it off with the wrench and vice-grips again 6) re-apply the braided hose to the outlet end, or replace with a new hose. Can anyone validate my approach? Is there anything I should watch out for? What is the expected lifetime of these valves? I'm a little surprised the old one started leaking already.

Thanks Matt30. I planned on shutting off the water at the main, opening the faulty valve, and then slowly removing the braided hose. I don't have any other faucets in between or after to help drain any water in the line. If you have a better suggestion, please let me know. I didn't think about the risk of using vice grips, thanks for pointing that out. I'll use two wrenches. Is there any harm if I let this drip for a day or two? We have a large snowstorm starting and I don't want to risk being without water for an extended period during a storm, so I may wait to try this repair.

You're going to want to release the pressure off the line before you take the old valve off. Otherwise you get an unwanted shower. Make sure you use two wrenches, not vice grips. With vice grips you risk deforming the female end. It's only red brass, not steel.

Unless something goes horribly wrong, it should take you only 10 minutes to make the repair. I'm a fan of applying both Teflon and pipe dope to the threads.
