Radiator Not Working -- Valve Change without draining

Changed my radiator valve without draining the system. Radiator not working -- Valve change without draining. I removed a broken TRV thermostatic radiator valve on my domestic radiator using my shop vac to catch the water and reduce the pressure in the heating system. If all goes well this only takes a few seconds to exchange the TRV and re-pressurise the heating again. This is a do it yourself project but you have to be careful not to proceed unless you have the water under control. There are times when it is better to drain the heating so that you can comfortable change the radiator valve at your own pace. This video is for information purposes and there is potential for things to go wrong. Be careful.
