The thermostatic valve (or thermostatic mixer) uses the same operating mode as a radiator thermostat. Equipped with a sensitive element, it allows you to deliver water at the desired temperature almost instantly without having to constantly play with hot and cold water taps. It consists of two handles: one for the water flow and the other which is used to adjust the temperature.
Installing a thermostatic valve on a bathtub: obvious advantages
To avoid any risk of burns, the latter is fitted with a safety catch at 37 ° C or 38 ° C, the ideal bath temperature for children. In addition to offering all the guarantees in terms of security, this mechanism also allows a gain in comfort. The water flows at the right temperature and constantly. Some models also offer flow limiters to reduce water consumption.
Choose a suitable thermostatic valve model
Before working on your installation, it should be checked that the water is turned off and that you have all the equipment at hand. Thermostatic valves are often sold as a kit but it is best to check that the necessary seals are provided, as well as the fittings. These must adapt to the diameter of your supply pipes. Your new tap should also be perfectly positioned between the two pipes. For this, it is better to measure the distance before buying an unsuitable model. Sealing is the key to success in plumbing. The teflon tape (or the joint compound and the tow) must be laid on the male fittings following the thread, that is to say in the direction of clockwise, so that the device tightness is deteriorated when you screw them on. After having screwed them to your pipes, you can place the decorative rosettes which are used to hide this junction. The seals are then affixed to the valve before it is permanently screwed to the fittings.
