    it's so you can boost the pressure by use of a pump on the mains i think

    Im looking at one without a pump. Iv got 3 bar and 14 lmin but it on 15mm mains. Looks to me like you jus run the mains thru it to the accumulator. With non return valves.

    I made a few enqs on these a while ago. Can't remember the company but they were very helpful. You have to connect it to the mains after the kitchen tap. You then need to set the pressure at whatever the highest pressure of the house is. you need to test the pressure at varying times of the day. if the highest pressure is 2.5 bar then you can set it at 2.5. That is the pressure you'll get. Apparently.

    They are just a large expansion vessel (for potable water)
    I've fitted a few with good results, main problem I've found is having a space large enough to install them.

    I haven't fitted the GAH one's but they have a decent diagram on the link below

    Thanks blod. Thats the sort of thing iv been looking for. I had it in my mind roughly how that looks. In gonna get a horizontal one an stick it in the loft i think. Ill lift all the insulation from under it an jus lay it over so it shouldnt freeze.

    If you've got a small loft hatch you can fit smaller ones in series. Advanced water have a good selection of different sized ones.

    I'd agree they are a dead leg, but would that then mean all the unvented cylinders fitted with expansion vessels don't comply with regs either ?
