Good to find in stock, does what it says on the tin
Fitted easily able to manually bledd by removing with fingers (seals with an O ring) to remove airlock in towel rail.
Well made, first very well and quite neat. Functions as it should.
Great device to remove air in radiators automatically
installed several of these to save time bleedin bleeding the system, they work great and leave the system maintenance free once pressurised
It would appear to do exactly what it says it will do. Not had it long enough to be sure.
A towel rail, the highest point in the circuit, slowly collected air such that a bleed was needed every six months to keep the top rail piping hot. Fitting this device cured the condition. Good after two years, though apparently they don't work indefinitely. I bought another after a similar condition in a gravity circuit and this works too. The chrome finish is of high quality and if they last they will be good value.
