Ariston Water Heater Expansion Vessel Kit A

It is working well after the plumber install it with the new water heater and piping. It is value for money as the price is lower than buying from the big brand 'Sxxxxfxx'.

Very good quality accumulator definate value for money. Easy installation with compact design, meaning less space taken up by system installation. Excellent buy.

This goes alongside with my all under sink heater been in the flat now for four years and no problems with it

Nice and compact expansion vessel easy to fit with most basic tools ,you will need to get a pipe T connection ...compression or push fit or a solder joint if you like, it came with check valve Very quick delivery

We had a loose section of polypipe in a wall and the washing machine caused it to make a noise when filling the machine. This is due to the washing machine water valve being an on/off type of arrangement rather than a gradual open and close like a tap. This on/off of the water flow means that the kinetic energy the flowing water has is brought to an abrupt stop and this can be transmitted back up the pipe as water hammer. Fitting one of these expansion vessels close to the washing machine allows for that kinetic energy to be absorbed inside the expansion vessel by the inflatable bladder rather than shocking your pipe work. You'll need a copper to iron fitting and a rubber washer to get it to seal, don't try a fibre washer as they just don't seal properly. You may be able to get a tap connector hose to work if you get stuck.
