Rated 3 out of 5 by from Expansion vessel The vessel is robust and very easy to fit and is at a reasonable price. I have fitted many of them and have never had any problems.

Rated 1 out of 5 by from Just over a year old... ... and it's leaking via a tiny rusty crack. I would expect at least 5 years lifetime of such product.

Rated 5 out of 5 by from No more F/E tank. Customers F/E tank was almost inaccessible, and could not be drained and cleaned properly. Too much sludge and other contaminants left his heating system in a poor condition. Fitted this, and used the mains pressure to flush the system. Added cleaners and inhibitor, and will be checking back in a couple of weeks. Should have fitted this ages ago.

Rated 1 out of 5 by from Failed after 2 years I'm usually a fan of Screwfix' own-brand products, but we had this installed by a professional and it failed after just 2 years. A crack in the metal sent water cascading into rooms below. Maybe worth spending the extra money on a reliable product when a failure of the product is damaging and expensive to put right.

Rated 4 out of 5 by from nitrogen filled (not air) my old unit that was directly attached to the hot water tank ruptured the (replaceable) bladder due to the cylinder having a pinhole in the metal and losing pressure. Thank heavens for screwfix click and collect at 6pm! This item does not have a replacable bladder - the threaded part is an integral part of the cylinder (hopefully easy to remove from the tank when the time comes). It is filled with nitrogen (inert) not air, and only to a precharge of 1.5 bar (not 3). The instructions say to increase if needed from a nitrogen cylinder (not got one so its left at 1.5bar). Also the label says max pressure is 6bar, not the 3 stated. If this was not an emergency I would have shopped around for a unit that can have the bladder replaced. I've no idea if nitrogen will actually prolong the life of this one. obviously to soon to grade performance and reliability
