"Needed a new Filling Loop as the old one was leaking through the gland, Looked on the web, Screw fix was local and had the part in stock at a good price, couple of minutes on the laptop and the part was reserved, Short drive to the Borehamwood store and had somewhere to park too, the staff at Borehamwood Screw Fix were very helpful and efficient, no messing about, Job done."
"Used this to replace one of the soppy one valve filling loops that always let by causing boiler pressure to increase. This on the other hand has 2 valves so doubly secures. Simple to install and no leaks for me. pretty good."
"Fitted this to replace a leaky filling loop on my parents' central heating. Fitting it couldn't have been much simpler (but then it's the same as pretty much every other compression jointed fitting!). Everything is also marked up nicely for flow direction so it's difficult to get fitting it wrong!
The easy to use tabs on both the mains water and boiler side of the loop make it very easy to use - far better than the old valve where you had to fiddle with a screwdriver to open and close the valves, and the valves just spun around and around causing them to eventually wear and leak. These just turn through the quarter turn needed to open and close the valves correctly.
The tabs are so easy to turn that someone with arthritis can easily turn the mains side tab and very easily control the fill on the larger boiler side tab.
A wholeheartedly recommended product, and supplied by the very efficient and friendly staff at the local Stoke branch!"
"I have bought two of these from Screwfix in the past year. Both have leaked immediately on use, once incoming pressure gets to about 1 bar. Leak occurs at a hairline joint beyond the on/off valve which connects to the boiler heating pipe. You can just about see the joint in the Screwfix image - it is next to the hexagonal shape at the left hand side. Find an alternative product."
