Very easy to change and you don't even need to drain the system, just need to be competent enough to do this yourself. Part gave me no trouble since changing it a week ago and my F.75 trouble seems to be over. I had also changed the expansion vessel prior to this, which seemed to be letting water into the air compartment, but fault still showed up so changed this too.

Said to be Vaillant however not in Vaillant packaging so would suspect a comparable product which will takes years to test as I bought one locally and fit as the next day delivery clearly shown as a benefit took a further two days for the item to arrive. If you want a compatible product then others are available cheaper. If you want next day then this is not the place to obtain it. If you want a true Vaillant then look at the packaging.

If you own a modern high tech gas boiler you must carry one of these as a spare, they have a short life but are cheap & easy to fit , they could save you a lot of money.

Did the job my self old was covered in muck my pressure needle was to the floor so boiler was empty my digital display was reading 1.6 bar swapped out for this new one and digital display read 0 bar so it worked just as it should. Very happy. Common problem for the alful boiler I have if it hasn't been repositioned.

It has only been fitted for 2 weeks but it immediately sorted out F75 error on boiler. Cannot comment on longevity of product but so far so good. Easy job for the plumber, don't in about 15 mins.

My plumber has fitted this and it resolved my boiler problem. As far as I can tell at this early stage, it's perfectly good. Also good value, arrived quickly and fitted through my letter box.

Arrived fast. Did the job. Good tight fit. No leaks. Bought a spare as seem to need to change this every 2 years or so. Not Vaillant original, doesnt claim to be and they dont last any longer so why pay more.

Regrettably, the wrong sized o-ring was sent with this item and cannot be fitted. I had to buy the same item locally at greater expense, so I have at present two useless items until the correct o-rings are obtained.
