Water Heater Pressure Relief Valve Outlet Size?
I have a stinky (mild rotten egg smell) water heater on my trailer that I need to deodorize with hydrogen peroxide. I am thinking of filling the water heater through the pressure relief valve. But I don't know the thread size to buy to appropriate fitting.
This is what I am trying to avoid doing:
Unfortunately I can't do much by trial and error because the trailer is at a remote campsite. The nearest hardware store is 80+ miles each way. The campsite is also 4 hours from my home. I am going up this weekend to get this and a few other projects done but time is very limited. I really don't want to pull the valve from the water heater if I can avoid it.
I guess the question is: are the outlets a universal size or should I bring a selection of sizes? I'm guessing 1/2"? NPT I'm assuming?
Thanks!
