REGULAR BOILER HELP (HEADER TANK IN LOFT)

[Ian Auckland]

Hello,

Please can you advise me on the following;

I need to do some work on my hot tap pipe work in bathroom. I can't use the gate valve as this is broken to shut of the cylinder fill pipe.

How do I go about shutting off the hot water without draining down the system?

Thanks

Just noticed there was been a development before I posted this, but still..

I changed the iso valve on the cold pipe from the tank a while back, as old valve seized. I didn't want to drain off the water to waste so I made up a mushroom shaped thingy out of a bolt, flat washer and some plumbers mait. Open a cold tap to a trickle, then reach down inside the tank and insert the mushroom into the outlet pipe. As the water drains from the pipe the head of water in the tank holds it in place. Sealed plenty well enough to do the job. You might be able to do it that way, on the outlet that feeds cold to the bottom of the HW cylinder, obviously.
As others have said, while you're at it definitely worth replacing the valve.

I’d not recommend this as you could get mait down the feed pipe and block things

The hot tap down stairs has been running for ages, water is running from the hot tap in bathroom now but there is deffo air still in there.

You should be fine now turn both off and let the tank fill then try again for a few mins

If its a mixer tap in the kitchen
its dead easy.....get a beer mat or something flat ...block the outputs from the mixer into the sink, use a g clamp. Turn the hot side on then turn the cold mains side on gently...open a hot tap upstairs and just blow the airlock out. it can get messy but works. then dis assemble in reverse order ...job done.

Hello it's not the kitchen tap which has the air in the line it's the hot tap in the bathroom. The header tank Is full and stopped gurgling but air is still trying to push out the hot water side (mixer tap in bathroom aswell). What should I do?

 

[ShaunCorbs]

Keep going until all air is out and get the broken valve replaced later on

So leave the kitchen hot tap open and the bathroom hot tap open? Does the bath hot tap need to be open?

Just open one at a time eg run the bath one till no spurting

Then do the others one by one

Maybe leave it tonight and try in the morning but if waters coming out you should be fine for now in regards to an air lock

I will do a small video of the tap running and post tomorrow. Thanks for your help.

I've used this method several times with no problem. There's no way a big lump of mait will get into the pipe, small piece highly unlikely but maybe just possible, and if it did it would come out via a tap.

Looks fine should sort it self out over a week under normal operation
