How often do you actually test your main water shut-off?

- Paint pen on the pipe - never thought of that, but it’s kinda genius for folks like me who lose track of sticky notes.
- I’ll admit, I usually just wiggle the valve every few months when I’m down there poking around for something else. Not exactly a system, but hey, it’s better than nothing?
- Hard water is the real villain here. We’ve got it bad, and I’ve had to replace a seized valve once - wasn’t cheap, either.
- Honestly, part of me wonders if I’m overthinking it. How often is “enough” before it’s just paranoia... every six months? Once a year?
- Anyway, I’m all for low-effort hacks, especially if it saves me from an emergency plumber bill.

I see a lot of folks just giving the valve a quick wiggle when they’re nearby, but honestly, that’s not always enough - especially with hard water in the mix. I’ve seen valves seize up solid after just a year or two of no real movement, and by the time you need it, it’s too late. Personally, I recommend a full open-and-close cycle at least twice a year. It doesn’t take long, and it’s way cheaper than replacing a stuck valve or dealing with water damage.

That said, I get the paranoia thing. There’s a line between being prepared and obsessing over it. If you’re already down there every few months, maybe just add a full turn to your routine instead of just wiggling. Out of curiosity - has anyone tried using food-grade silicone grease on the stem threads? I’ve had mixed results depending on valve type, but it seems to help with longevity in some cases...

I’ve actually tried the food-grade silicone grease on a couple of older gate valves, and it did seem to help with smoother operation, but I noticed it can attract dust or grit over time if you’re not careful. For ball valves, I’m not sure it makes much difference since the mechanism’s a bit different. I agree that just wiggling isn’t enough - twice a year for a full cycle feels about right, especially with our hard water. It’s one of those things you only regret skipping when you really need it...

Twice a year’s pretty solid, especially with the hard water - mineral buildup can really mess with things if you let it go. I hear you on the silicone grease picking up grit, though. I usually wipe everything down first, then add just a thin layer… seems to help a bit. Ball valves are kind of set-it-and-forget-it, but I still like to give them a quick turn every now and then just in case. You’re right, nothing worse than finding out it’s stuck when you actually need it.

Can’t say I’m as consistent as twice a year - usually just once unless I’ve got a reason to mess with it. I get what you mean about the grease, though. I actually stopped using it for that exact reason; seemed like more trouble than it was worth with all the grit. Ball valves do seem to hold up better, but I’ve still had one seize on me after a few years of ignoring it. Guess a quick twist every now and then is just cheap insurance, even if it’s a pain.
