How to replace a three way motorised valve - Plumbers Videos - Plumbing Tips.



Hey everyone, I’m glad you found this guide on replacing a three-way motorised valve! If you’ve ever been in a situation where your hot water just won’t turn off, you understand how frustrating that can be. Today, I’ll walk you through the process of replacing a 3 port valve, which is a common culprit for such issues. First things first, before diving into the replacement, you need to ensure your system is totally drained down. This is vital to avoid any water mess and keep the area safe while you work. Make sure to bung the tank to prevent any accidental spills. Safety first! Once your system is drained, you can locate your three-way motorised valve. It’s usually found close to your boiler or hot water cylinder. Disconnect the electrical connections, noting their positions for reinstallation, and then remove the valve from the pipework. Depending on your setup, you might need to use a couple of different tools to get it off. Now comes the fun part—installing the new valve. Just reverse the process you used to take off the old one. Make sure all your connections are secure and that the O-rings are properly seated to prevent any leaks later on. Once everything is back together, you can reconnect the electrical connections based on the notes you took earlier. With the new valve in place, it’s time to refill the system. Open up the valves and let the water flow, checking for any leaks as you go. If all looks good, turn your system back on and test it out. You should find that your hot water behaves as it should. Replacing a three-way motorised valve can be a straightforward task, so don’t shy away from giving it a go. With a bit of patience and the right tools, you’ll have your plumbing back on track in no time. Happy plumbing, and don’t forget to check out the video for a visual guide!
