    Hot water cylinder leaking around joint with hot water inlet

    I'm trying to remove the zone valve ion vented tank and the tank started leaking around the joint. I was hoping to just run the tank with immersion till I can get an unvented. Any tips to stop leaks or do you think I need to buy temporary tank. Any help appreciated as I'm without hot water now.
