In a shower, the water flows to a mixer tap or thermostatic mixer where the temperature is adjusted for comfort. From the mixer, the warm water flows through a single pipe to the showerhead. East London Plumbers can fit all mixers.There are three types of mixer:1). A combination bath mixer tap and shower.2). A manual shower mixer.3). A thermostatic mixer.In the first, that average of the water is adjusted by turning the hot and cold taps until the water running from the mixer tap is a suitable temperature, and then operating a button to divert the water to the showerhead. This is a good option if you want to keep the running costs down. In the second, a manual mixer features a single control for regulating the temperature and flow of water in the shower. While this is a good low-cost option, it’s not such a good idea if the shower is intended to be used by children or elderly people.In the third, the mixer incorporates a control to preset the temperature of the water. They are a little more expensive than ordinary mixers, but well worth the extra financial outlay on many counts. They are much safer to use than other types of shower because the temperature is regulated. If someone uses hot or cold water elsewhere in the house, a thermostat mixer instantly adjusts the water flow so that the temperature of the shower remains the same. The temperature dial operates independently of the on/off control, so the temperature setting can be maintained when the water is turned off. When you next use the shower, the temperature will be exactly the same. This is a good option when it is intended that the shower will be used by children or elderly people. It is also possible to get fail-safe units that can be locked to a safe temperature. The mechanism inside a thermostatic mixer shower is complicated. An East London Plumber understands mixers. The temperature is controlled by a small wax field piston or a bi-metallic strip mechanism, which continually adjusts the flows from hot and cold pipes to give a constant outlet temperature.
