Water supply valve replacement


I need to replace a supply valve in a closet of water heaters within a building of several units. If I turn off the water main and remove my bad supply valve.....will the water from all the other water heaters and floors above drain out from the gravity?? I just want to know if turning off the water main will be unough for me to cut pipe & replace my water heater supply valve...Thanx

The whole building is going to drain--slowly.

Consider using a JETSWEAT tool----it is a tool that slips onto the pipe and has an expanding plug---

Slip the valve on over the slender handle--sweat---remove ---close valve

Thank you Mike for your response, I am very excited to learn about the Jet Swet tools and will certainly add them to my tools, however I need the replace my supply valve because it is broken in the closed position, It does not look like this can be used on a valve in the closed position. What do you think??

While the water is off anyway...
spend another $100 or so on a few additional service valves so you can isolate easier.

OP---Have the city shut off the water----cut the pipe on the meter side----then cut the building side and quickly shove the tool into the pipe and twist the handle----

clean the pipe --and new ball valve---flux both surfaces---and slide the open valve over the tool and onto the pipe.

Solder----remove the tool and close the valve.

This tool is a life saver--I used it on a live 3/4" main line when the Buffalo box couldn't be located under 2 feet of snow.

( Just a thought---most areas require a licensed plumber for multi family dwellings)
