You have probably by now exceeded your skill level. If you turn it off quickly does it get anywhere moving in the problem ones? As its only the two you have a problem with, personally I would lift the floor above and trace the pipes. I don't suggest you do that. I might have put a water vac on...
I still would have expected you to have water both sides. If it is a one pipe system it will not work properly with a Trv. Open the valves fully and take the Trv heads off. It still might be a two pipe system with a blockage. All of this is difficult to diagnose without seeing the system. I am...
If the radiators that are not working correctly are on the second floor would be the only time you may find a vent in the roof space. To completely check the pipe you really only need to take one off and pull water through the side that is not heating. Connect a hose to the valve and open. Clean...
The flow to the radiators is usually on the trv end. Unfortunately the manifold could be anywhere. Are you in a house or bungalow? If you are in a bungalow there could be a vent in the roof space. Locating the manifold may not help you. You may have to bite the bullet and take a radiator off...
It could be you have an air lock. If you close off the end that gets warm, try venting the radiator with only one valve open. If the other radiator is connected to the same drop close both ends of that. Then try. See if you can pull water down the pipe. Close radiators off again and check. Good...
The tap will have to be removed from the sink to repair it, and from your photo it is soldered pipework not compression. So unless you can solder or you want to change the tap tails to compression/ push fittings it may not be a job you can do yourself. A new tap comes with new tails most likely...
Have the radiators always been cold even when valves are fully open? I attended one property that had a kinked pipe in the wall. Have you taken one of the radiators off the wall to check if you have flow through both pipes?
A customer rang this morning, says they have a intermittent fault on the boiler P3. Its a Worcester CDI30 I think from a past visit. I did quote for a new boiler 10 months ago, but the old one is still hanging in there. I looked on line as I don't have the book with me. Any suggestions? He says...
Its probably the diverter valve. I had a customer with the same problem. They said the only way they could stop the noise was to run the hot tap. When I arrived to look at the boiler no noise. But I hung around and had a coffee and while I was there the noise appeared. It is an easy fix for a...
