Changing the radiator valve

Changing the radiator valve

It is common to hear that you don't improvise as a plumber. The change of a radiator valve is however within everyone's reach. It just requires being meticulous and investing in a little hardware. A leak at a tap? Or do you want to replace your old radiator valve with a thermostatic model to save money? With a pliers, a little joint compound and tow, you can easily overcome this problem.

Removal of the old radiator valve

The first step is to bleed the radiator. Using a pliers, just loosen the bolts upstream and downstream of the tap, remembering to place a bowl below in case there is a little water in the circuit. If the radiator has been painted, it may happen that there is also paint on the nuts. It is then enough to scrape it lightly to release the bolts.

Ensure a good seal at the radiator valve

After brushing the end of the pipe with a wire brush to ensure a good seal, you can generously spread joint compound on the tap connection and the end of the supply pipe. Then, you wrap the tow (available in all DIY stores) clockwise still on the supply pipe. It remains only to screw the new thermostatic valve with the bolts, tightening properly. When the radiator is put back in water, it is preferable to check for some time that it does not leak. If so, just tighten the bolts. And voila.
