Don't brake your waterheater, mount a good 4 bar pressure relief valve

Something is wrong because my water system looses pressure all the time. Then I discover my relief valve on the water boiler is leaking a bit of water and I plan to try to fix it. I think the reason for the failure is rust from a galvanized plug that rust over time and it do it incredibly much when combined with brass. I have bought the new valve at www.hedestoker.dk
