Re: Radiator Valves - Replacement not so Easy!
Even if you plug up the expansion tank in the loft (old plumber's trick is to use a carrot), there will most likely be a degree of water spillage, so the best bet is just to go for it, drain the system down and change all of the valves at once.Re: Radiator Valves - Replacement not so Easy!
For what it's worth, while you've got the radiators empty, now is a good time to take some of them outside and flush through with fresh water from a hose. You'd be amazed how much crud is in them.Re: Radiator Valves - Replacement not so Easy!
Re: Radiator Valves - Replacement not so Easy!
You certainly can plug the water tank (the small header tank) with a set of rubber bungs. I have used them many times and only once did they not work because the pipes were out of shape.Re: Radiator Valves - Replacement not so Easy!
