How to cut into hot water line?


I am wanting to cut into the hot water line leaving my hot water tank in order to put in a temporary line to feed my washer. There is no shutoff valve from the tank to where i want to cut. What do i do?

Can you not shut the whole house water off, while you perform this plumbing change? Open the faucets, and drain as much water out from the pipes as you can.

Your welcome be careful go slow it might take some time to DE pressurize it. Don't just cut in make sure you drain the hot water till no pressure.

Turn off valve above water heater or turn off main water valve.

Turn off water heater heating (flip off breaker for electrics).

Open some hot faucets upstairs.

Drain about two gallons from the water heater drain valve (to make sure all the water in the pipes above you comes down.)

Now you should be able to work on the pipe without getting wet.

Turn the water back on and observe water flowing from a hot faucet before turning the water heater back on.

You can remove the drain tube from the relief valve and install a 3/4" nipple with a reducer on it that can attach to your air compressor. Hold the lever on the relief valve open. Use the compressor to drain the tank then the the water lines by opening up the lines via the faucets. Make sure the breaker is off and the main shut off valve for the house is closed or if on city you can turn the valve off at the meter.
