    Where can I get the right size bleed key?

    I have some Pegler Terrier lock shields with drain off capability. A standard bleed key is too big as it appears they use a smaller square head on their valves. Anyone know where I can get a bleed key to fit. Thanks Graham

    How to bleed Y plan system?

    hi everyone, I’ve just changed my circulation pump and I only noticed before re-fitting that the diverting valve was set on HW. So I must’ve drained the HW side to just below pump level? Then I refilled and turned it on. Is there any way I must bleed it now as it’s the HW side? Sorry if...

    No bleed valve on radiator?

    Hi, One of my radiators has developed a trickling sound once the heating is on. This used to only happen as it first turned on and then it went away, now it is constant when the heating is on. After some research I understand this to mean there is some air trapped in the radiator (though the...

    Bleed Value problem - not vent all air

    I have a problem with a new radiator (badly designed) where I need a bleed value that bleeds from the top instead of the middle of the value. Don't know if there is such a thing, can't find one. The issue is that the radiator has 4 upright columns that are linked at the top by a round pipe. The...

    Hi, I've drained down a conventional vented heating system (c. 1998) and and trying to re-fill. The fill & expansion tank is nicely filled, and I have got a small amount of air out of some of the downstairs radiators, after having set the 3 way valve to M(id).

    Double radiator bleed screw puzzle

    I've just drained my standard gravity fed system and replaced a couple of TRVs. I'm just about to re-fill, but I have noticed that a couple of the double radiators only have one bleed screw. Some of them have 2 screws as I would expect, one for each half, at the top on the "inside" of the...

    Bleed Valve Keys Won't Fit On Older Rads (Inc. Pictures)

    Just a quick one. I have two different bleed keys (see photo), and neither will fit on the bleed valves of some older rads. I'm not 100 per cent sure, but I think they may fit on the square screw that turns, but it's the circular collar around the screw that's stopping the key sliding over the...

    Vaillant Ecotec Bleed/Purge Program Questions

    Just a couple of quick questions about an 8 year old Ecotec Plus 831 combi (R1). Will this boiler have the bleed program function? I don't have the manual, but looked in one online and couldn't see it listed in the contents or on the filling page. If this boiler does have a bleed program...
