    Hello Fella`s

    just a quick nip in for Info ( You`ll normally find me in the Sparky`s Forum - But don`t hold that against me !0

    My Daughter has a problem with a 2 or 3 Port Valve on her CH System , House is always Hot , But Rads aren`t , I had a quick look the other week and the Valve does`nt seem to Switch over when demand supply is switched ie HW-Htng , She spoke to a Plumber he said it may be the actuator and it needs checking - is this on the Valve ?
    And how do u check it

    Cheers.

    a 3 port valve (mid position) has three 3/4 fittings. A two port has two fittings.

    The actuator has probably ceased. This is a quick repair. However, there may be a problem with external controls. Also the valve itself may have stayed open

    By all means change the valve if you feel Lucky, although personally I don't think it will solve the problem.

    More info is needed on the system and how its piped up, its age, and the boiler, cylinder etc for starters.

    Hello Fella`s

    ta for the replies,
    It`s a Barrats type House

    Cylinder HW Upstairs - Valves alongside , Exp tank in Loft , Boiler ( Potterton Wall Hung) In Kitchen , So I think you guys call it a Gravity HW and Pumped Htng ?

    Have to double check the valve , Pretty sure it`s a 2 port Jobbee with another next to it in the airing Cupboard alongside the Hw tank.

    IF it has 2 x 2port valves it's an S plan (fully pumped not gravity).

    The point with my earlier post was;

    How can the house get hot if the rads don't

    In answer to your question: you can manually open the motorised valves by sliding the lever on one end across and latching it into the little notch.

    Does the HW work ok?

    There's nothing wrong with the valve, or else the rads would get hot.

    How many clues do we need

    Just responding to the request as to how to test the valves: open them manually and feel the rads getting hot.

    Sounds more and more like a wind up to me.
