    I replaced a washer on the hot tap sink ( mixer), since then when you turn hot tap on it makes a loud rattling noise( it's LOUD) but you turn the tap a little bit more and noise stops.
    Done a bit of internet searching, so I'll give this info if it helps . The boilers pressure gauge is right at the bottom line of the green segment.
    Any help?

    Do you have a high incoming pressure?

    @rpm@rpm , no I don't think the tap has ceramic washers.

    @ShaunCorbs@ShaunCorbs , not sure what high pressure is but water shoots out at what seems to be "right"

    How can changing tap washer cause this problem? (If it is the cause. But it started right then.) I thought it might be that I didn't tighten everything up, but no.
    Internet reading says could be boiler pressure but I'm sure pressure is same as it's always been.
    Anyhoo, my dads got that BG plumbcare policy so he can use them.
    PS, couldn't believe how much he pays for boiler care. Damn, it's not cheap is it.

    Could be that the washer isn't the correct one. If the washer is loose to the valve, it will oscillate, giving the hammer effect. Check and replace
