Rated 5 out of 5 by from Fit and Forget This was a swap for a very unreliable Myson. The one that sticks and requires a persuader to help it along. The Honeywell unit was easy to fit the instructions were good and the job a breeze. If you have to replace a 3 port use Honeywell the reviews alone will tell you it's the only real sensible choice to make if you want trouble free central heating and hot water control. A week prior to swapping this unit I used Sentinel X300 product to flush out the system and after flushing fitted the valve and introduced the Sentinel X100 inhibitor. The whole system is running like new and more efficiently than ever.

Rated 5 out of 5 by from Dont go for a cheaper option Honeywell are regarded in the trade as an industry standard. Don't bother trying to save a few quid going for the cheaper alternatives. Buy once fit and forget it

Rated 5 out of 5 by from great new for old my old 3 way value motor was broken so this was a direct replacement and very easy to swap. Product feels solid and well built and easy to fit, only time will tell how long it lasts but the previous had lasted at least 20 years.

Rated 5 out of 5 by from Good value Purchased this valve to replace the one on my heating system that was stuck in the open position. The job was far lest tricky than I feared and the cost of the part was great compared to getting a plumb in.

Rated 5 out of 5 by from High quality valve The original V4073A in my system performed faultlessly for 25 years until 2010. In November 2010, I purchased a replacement V4073A from Screwfix which turned out to be faulty. When switching to DHW mode the valve would open 2 seconds after the pump started, causing the water to hammer. As it was winter at the time and the valve was otherwise functional, I decided to put up with the hammer until I next drained the system. Incidentally, the valve was made in Canada. Fast forward to May 2016. I drained the system in order to move a radiator and I took the opportunity to fit another replacement V4073A (this time made in the EU). I’m pleased to report this valve works perfectly and I expect it to give another 25 years' faultless service.

Rated 5 out of 5 by from Y Valve Bought this to replace an IDENTICAL one fitted about 28 years ago! It has worked faultlessly until recently when we no longer wanted the central heating on just hot water. It no longer sealed properly causing some radiators to feel a little warm. If this direct replacement - same model number and identical in apearance lasts as long it won't be troubling me next time ! Avoid cheaper alternatives you get what you pay for. It speaks volumes that they are still unchanged after 28 years - I wonder when the first one was made?
