    hot water circulator pump vibration

    Hi everyone, My flat is located next to a communal boiler with a hot water circulator pump ( Grundfos UPS 15-50N Secondary Hot Water Circulator ). The pump is noisy and vibrating. Would installing a more powerful pump solve the problem? Many thanks for your help!

    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.
