"Never had any problems with these TMV's. They are very well made, WRAS approved and if maintained will last a long time. Bear in mind that when installing these, your hot and cold supplies need to be of equal working pressure, otherwise the valve will not perform properly!!!"
"Does what it says. I fitted one on my bathroom basin as the water from my combi boiler gets too hot for comfort. Now the water is a constant temperature . Not having integral service valves is a pain as it makes the fitting very wide when these are added but compare the cost.Excellent value."
