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

Hello Ian,

You can isolate the cold water storage cistern (cwsc) in the loft (the one that feeds the cylinder) or turn off your cold main and then run hot taps until they stop. I would also recommend changing your gate valve whilst this is drained. Also if the cwsc has no isolation valve I would recommend fitting one.

Thank you CBW1982 for your reply. I am just worried about causing an airlock in the system if I drain it down?

That could all depend on your pipework layout, if there's any slight rises, or passover bends, then you are likely to either way, air locks are usually easy to rectify anyway.

Just tie up the ball valve drain down hot off you go. Check there is a mains water supply in bathroom as cleaning teeth in tank water is not nice, did a job with dead pidgeon in cold water storage ..the water stank

Yes no problem. If it’s a straightforward setup, should be relatively easy without causing an airlock.

Open all the taps when draining down then turn the water back on once finished and then when water starts coming out the taps turn them off. Dont turn them off before you start filling above found this is when I have the most air locks.

Thanks for you help people. I will proceed with the pipe amendments tonight, and let you know how I get on.

Hello amended my pipe work. Turn the mains feed back on left hot water taps on and I'm getting hot water out the kitchen sink tap and bath tap. Its splurging like theres air in the system and the header tank is making all sorts of gurgling noises. No water coming out of the hot tap tho it did for short time but stopped completely? Can anyone help?

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.

Keep running the kitchen sink until it’s free of air
