My flat has a Vaillant Turbomax 828 boiler that has been losing pressure since we started using it this winter. I have to top it up evry couple of days and have noticed a small leak from the PRV and drips from the overflow outside. I've spoken to a couple of guys about coming to fix it and the prices scare me a bit. From what I can tell it needs a service, possibly the PRV and maybe the expansion vessel replacing. I'm wondering if these are the sort of jobs a keen DIYer can do themselves? I'm pretty handy and have read quite a lot online about how to carry these tasks out but I know gas boilers and central heating can be dangerous and complex. Any advice would be welcome and very much appreciated... *
