Water Main Shut Off Tool

That is an invaluable precaution that should be taken when someone goes on an extended vacation. Just be sure that the electrical/gas supply is shut off on the water heater so you don't risk damaging the element/burner.

Good point. I always kill the breaker to the water heater whenever I shut off the water to do a plumbing project. When you start opening faucets It's easy to create a back siphon condition and have a situation where you might expose the top heating element.

If that happens you'll be installing a new water heater in addition to whatever else you were working on.

Turning off the cold water supply valve to the water heater helps to prevent this as well.

If you're shutting the water off at the meter, wouldn't everyone in the house know "there's no water" and won't be emptying the water heater by trying to take a shower, run laundry, etc ?

I would hope so; however, some folks give home access to a friend/relative/neighbor to come by to bring in mail, feed the goldfish, or do a security check, etc. when they go on an extended vacation (e.g., OCONUS, cruise).

No, I meant if you were just doing a quick repair like OP was doing. I do put our water heater in VAC mode and shutoff the clothes washer supply.

be careful with ball valves and shut off slowly. otherwise the water hammer is insane. all of my outside hose bibs are 3/4” full port ball valves and the wife has slammed them closed a few times…. paranoid about blowing my pex apart.

I keep a “big T” in the garage - but installed a 1” ball valve at ground level that you can close with your foot …
Have a little hot box and heat lamp that I pull out in the winter …
GFCI plug is right there …
