This is solid and well made. Prices for similar, if not the same product varies on the internet but images are the same. This was true to the image on the website and cost less than most others. It is pre pressured at above .75 bar. It is identical to the one I needed to replace in my Vaillant ecotec pro 28 boiler, apart from a slight design change to the moulding, around the pressure nozzle, it weighed the same as the old part and fitted like a glove to the boiler. There been no change to the boiler pressure gauge after setting the heating systems pressure at 1. 7 bar, in three weeks, indicating the new unit is doing its job fine and dandy. Well 😁

The expansion vessel in our valliant boiler gave in after 5 years. I was quoted well over £150.00 for parts and labour. At just over £35.00, I took a gamble and it paid off. Replaced the part in under 15 minutes, and now my boiler is up and running so smoothly. Thanks for the great item UNVENTED! Just to prove that valliant use the same expansion vessel in the boilers, I have uploaded a photo of the old one.

The parts are the exact spares not a cheap pattern version, therefore amazing value, accompanied by a very fast turn around and boiler up and running again. Will definitely use again.

Bought this as a replacement in my Vaillant boiler. Fitted perfectly and already pressurised to 1 bar. Handy washer with it too so saved hunting around for one. Same model British Gas fitted last time the diaphragm split, this time cost me a third of the price. No downsides identified.
