    Hi,

    I've had a leaking hot water tank for about 6 yrs, it's just a very very slow weep but it's about time I fix it. :!:

    So a friend of mine had his heating system switched over to a combi so has a <2 yr old tank going spare.

    It's exactly the same size and pipe positions as mine, so I thought great an easy job :D

    Unfortunately after draining the hot water tank and disconnecting the leaking tank I discovered that the compression fittings are 28mm and not 22mm like the old tank.

    My question is, is there such a thing as a male 28-22mm compression fitting reducer, I can find reducers that do 28-22mm but they are always female to female (If I'm assigning the gender the right way) ;)

    If there isn't whats t he best course of action.......

    Cheers

    Paul

    Better way - get 22mm x 1" connectors, available in male and female.

    Yes, that does make sense, modify the tank to fit the pipework rather than adding something in between :)

    Like this: http://www.screwfix.com/p/conex-male-coupler-302-22mm-x-1/64912

    Guess I should check the diameter of the thread pattern inside the tank once I've removed the 28mm coupler already fitted to the tank.

    Thanks for the reply.
