Only if you don't mark it so you remember which way is which and so others know.

If it were me, I'd fix it, but I'm fussy that way.

Meh. I'd grab a sharpie, draw an arrow and write "off" in a visible place close to it.

I am lazy.

I'd just take a sharpie and mark the new positions.

Is there some kind of screw holding the handle onto the valve? I'm thinking about the handle for one of the hoses at work. It has a small square peg with a threaded hole in the middle on the faucet side, the back of the handle has a square in it with the hole, we are missing the screw. If the screw is loose, it's possible that the handle was backed up off far enough to not spin the valve the first time you moved it. And you have unintentionally re-indexed the handle on the valve. If this sounds like what your valve looks like, then just reindex it the right way and tighten the screw.

If it is not like this and it doesn't seem like there is any way that the handle could spin without the valve moving, you might want to replace it even if it's not leaking. That doesn't mechanically make sense how that could work, that might cause you problems at some point, like the next time you need to use it.

It's also possible that it's not fully turned on in this situation. Like it could be about 3/4 of the way open, enough to give you the water pressure you would expect out of one or two faucets at a time.

Loosen the handle and remount it in the correct position

Is it a quarter turn handle or a multi turn one? For the former the handle needs to be removed and rotated 90 degrees. For the latter, there is no correct position.

I had a situation where the main shut off would not shut off. I called the city and they came out and shut off the water supply to the house. The main shut off used a rubber washer that had broken up. The guy who came out told me to go and get a gate valve of the same size as the original. He came back and installed it for me. Days later I noticed that the water meter was not turning. Called the city again and they came out and replaced the meter. Turns out the broken washer in the old shut off was caught up in the old meter.

The handle is 90°out. It will only get worse and usually pretty quickly.

Walk away

Is it possible the handle turned 90’ on the shaft?(assuming it’s a ball valve)

I take it this is a lever valve.

Remove screw. Pull off handle. Rotate handle. Place back on. Replace screw.

Simple fix. Reverse the polarity of the neutron flow.

Devil's work. Burn everything 😎

It’s missing the Flux Capacitor. Home Depot has them on sale.

You sure you just didn't get confused? The way the lever is positioned will tell you open or closed

That is now the off position.

So on is off and off is on? What’s the problem, just remember that

Remembering that isn’t the issue. Why it happened and if there is a potentially a bigger problem on the horizon is.

It is a ball valve. I don’t feel like that occurred but will check after work. Thanks for your input

Would this problem effect my Heisenberg compensator? I’ll need it functioning properly to get to the Depot safely.

I’m sure. It’s a ball valve. The water worked fine. I tried to turn it off. It just kept coming. I turned it back to the on position and it stopped

For a ball valve, open position is normally with the handle parallel to the pipe. The only thing that makes sense is your handle turned independent of the valve somehow. Most metal valves have a keyed hole and shaft, so this shouldn't be possible. I think pvc valves have the handle press fit with an indexed shaft, so same thing there.

Really, it doesn't matter. If someone opens it they can figure out that it needs to turn 90° no matter what direction it's facing.

Sure you didn't turn it the wrong way first and spin the handle on the shaft?

Well it may be broke somehow then

wow, this guy is on the up and up.

That would require recalibrating the flux capacitor!

No, but the Bohr valve may need re-Bohring.

Appreciate you LD!
