Rated 5 out of 5 by 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. 14 May 2016
Rated 5 out of 5 by 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. 12 May 2016
Rated 5 out of 5 by 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? 10 May 2016
Rated 5 out of 5 by Mid position 3 port valve Fitted today as a replacement, time will tell if its as good as the other reviewers say, bit on the pricey side. 28 Mar 2016
