Pressure relief valve is one of those things I always wonder if it’s actually doing anything until it’s too late. I had a slow drip once and figured it was just condensation—turned out to be a failing valve, and next thing I knew, the garage floor was soaked. But here’s what I don’t get: how often are you really supposed to test or swap those out? Some folks say yearly, others say just leave it unless it leaks. Seems like overkill to replace something that’s not broken, but then again, water damage is no joke...
Funny thing—I've seen more water heaters ruined by a $15 valve than anything else. I usually test mine once a year, but replacing them? Only if they start acting up. Curious—anyone ever actually had one blow out completely, or is it just me worrying too much?

Yeah, those $15 T&P valves can be sneaky. I get where you’re coming from—most folks don’t swap them unless there’s a drip or they won’t reset. I test mine every year too, but honestly, I’ve never seen one actually blow out. Usually, it’s just a slow leak or a bit of corrosion. If you’re worried, I’d just keep an eye out for mineral buildup around the valve or any weird noises. If it sticks or won’t seal after a test, then it’s time to swap. Otherwise, seems like overkill to replace it just because.
I hear you on the T&P valves. I used to just ignore mine until one day I noticed a little puddle under the heater and thought it was just condensation. Turned out the valve was slowly leaking, probably from mineral gunk. After that, I started testing it every spring when I drained the tank. Haven’t had to replace it since, but I do get a bit paranoid about it failing at the worst time. Still, I agree—no point swapping it unless there’s a sign something’s off. Those little things add up if you’re not careful with the budget.
“no point swapping it unless there’s a sign something’s off. Those little things add up if you’re not careful with the budget.”
I totally get that—sometimes I wonder if I’m being too cautious or not cautious enough. Does anyone else get nervous about testing the T&P valve, though? I always picture it spraying everywhere or not sealing back up right. Is there a trick to doing it without making a mess? Or am I just overthinking it? I’d rather not replace stuff unless I have to, but then again, I don’t want a surprise leak at 2am either...
