"I bought two of these to replace those in the cold water storage tank and the central heating header tank - the threads are well cut making changing the body of the valve over to the existing connector a simple, easy and above all quick job. The valves are well made from heavy duty brass and have a quality feel about them; water inlet is quiet with a clear and obvious shut off. When combined with a new float, a less than £7.00 repair per tank that will last another 10 years."
"I had problems with the old float valve in the cold water tank on top of the hot water cylinder. I had replaced one previously for the same problem. As the water entered it was causing the float to bob up and down in the rising water, which created a light "hammering" in the pipes. Read other reviews and took their advice. You obviously get what you pay for. This valve was slightly more expensive but seems to have cured the problems instantly. Time will tell. Good product and in stock at the local branch."
