    What is the pressure in this cylinder expansion vessel?

    I was told by the plumber to keep an eye on the pressure, to ensure it stays above 1.0. The red one is… but the black one is not…. What do the two mean?

    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.
