Also, how do you check a diverter valve on a boiler?

After you remove the lid of the boiler, you have to locate the diverter valve mechanism. Run tap water on hot and observe the diverter valve. If you run hot water, the valve is supposed to close in order to divert it to the tap, meaning it should move. If you see no movement, then it's stuck.

Also Know, how long should a diverter valve last? Now that you've diagnosed the problem, you should call out a gas safe registered engineer to come and replace the diverter valve or service the working parts of the valve.
