Water heater busted this morning, after a couple of hours the water was turned off at the main in the yard.

Now how can I cap off the hot water heater in order to still have water in the house, I can't get a new one until next weekend.

Please help thanks

    Don't you have a cut-off valve on the cold water supply to the water heater? If not, do you have copper lines or PEX? You could cut the line and put on a Sharkbite cap. – Jim Stewart Jul 29 '19 at 21:16

  • Jim Stewart I see 2 copper pipe one on the left side and right side at the top of the heater and 1 water valve. – Mary b Jul 29 '19 at 21:34

    It is often the case that the supply line going into the water heater has a shut off valve for just this reason. If you can look on top of the heater it may have labels for in and out or color codes, blue in and red out. If the valve is on the IN - side then shutting it will stop water from going into the water heater and allow the rest of the house to have the cold water supply. ( yours could be different but without more info we can not say. ) – Alaska Man Jul 29 '19 at 21:44

    @Maryb as new contributor you can not ad the photo directly ( i believe ) but you can post it elsewhere and post the link then someone here can copy it add it to your post. PLUS ad more info on what "BUSTED" means. Ad a detailed description of what has happened. – Alaska Man Jul 29 '19 at 22:11

Turning off the valve at the hot water heater will stop the leak while no faucets are in use. If you only use cold water everything will be ok but if a single handle valve is turned on with some hot and cold the cold water pressure can return to the water heater and the leak may start again. Make sure to only use cold water and turn off the supply water and gas/ electrical to the water heater, no reason to waste $ on a broken heater
