Fits Perfect
My current Baxi boiler system needed topping up on a daily basis so bought the ARB18 Expansion Vessel (Baxi Megaflow system) Package Content : 1x ARB18 Expansion Vessel (Baxi Megaflow system) Fittings The item arrvied sooner than expected, kudos to the seller. It was a like to like expansion vessel. Initially I thought the image on the product listing has like an oem - non label and non branded product. When it arrived it had all the labels as on the already fitted ARB18 Expansion Vessel (Baxi Megaflow system) . The existing ARB18 Expansion Vessel (Baxi Megaflow system) was installed in 2003 and the registered engineer said the reason I have to keep topping up the system on a daily basis was due to the expansion vessel. The installation was very simple, the engineer powered off the mains of the boiler and replaced the vessel and restarted the system and it was all good. Definitely recommed the seller and of course the ARB18 Expansion Vessel (Baxi Megaflow system) if you are looking for one. I really hope you found my review helpful and would love for you to click on the “YES” button to say so.

Poor instructions and slightly misleading description
The instructions are quite difficult to read, the text us ridiculously small and also don't cover much. I'm interested in how to service this and I don't feel the instructions really support me. Also when I purchased the description said "The vessels are supplied with a replaceable membrane" , I assumed this meant an extra/spare membrane for the service......which it doesn't.

Product exactly as required.
This was replacement for an expansion tank that had stopped working. Good price for the product from this seller and very quick delivery. Does the job.

Bracket position
The bracket position was exactly the same as the vessel that I replaced, which made everything easy.
