Ask the Question

I've recently replaced my bathroom suite. After I'd put the new basin in and new mixer tap to match, the pressure on the hot water has dropped right away. It's exactly the same at the only other hot tap in the flat (mixer on kitchen sink). The hot water had always seemed to have a bit of an air lock in it which would gurgle and blow out after running taps for 15 seconds or so, but i'd never got round to sorting out.

System is a copper tank heated by immersion (no boiler, don't have any gas supply). The tank I assume is fed by a header tank which must be in the loft. Access isn't easy so i've never been up there.

Any ideas - air lock perhaps? There's a nit of gurgling noise in the pipes. I would try to force the air out by linking cold to the hot as I've read can sometimes work. I've only got mixer taps in the flat, so is there another way I could do this? I also wondered whether the gate valve on the cold water flow into the tank is perhaps not opening fully.

Thanks for any assistance.
Anthony

Problem solved via a tip on diynot. Sponge in a plastic bag held over the end of the mixer tap. Cold water on, then hot, wait a while then hot tap off then pull away the sponge. Worked first time and don't have to wait 5 minutes to get a bowl of hot water now!
