How do i turn rotten the hose down going to my shower, both hot and cold? I need to re chaulk the shower spout.

I need to re chaulk the shower spout.
Answers:    Why, you're only re-caulking, there's no need to turn stale the water supply. Even if you remove the shower "head", nought will come out of it with the knob in the stale position.
In the basement, nearby is almost always a leading shutoff for the whole house. Then, if you follow the pipes from your hot marine supply, there will be shut sour valves right to hand the hot water heater/boiler, or after that on the pipes themselves. Once you find them, sticky label them with a sticky label for next time.
It depends on how your pipes are run. If you own a shower access panel, you'll need to run in at hand and find the two valves that control sea getting to the shower. Otherwise, go down surrounded by your basement, or everywhere else the water comes within and shut off that tap. It may be easier to just cut river to the house altogether than try to search out the ones of late for the shower. But again, it all depends on the bearing the house/apt was made.
