no water coming out of hot taps

[andrewroberts1968]

i have a cylinder full of water, tank in loft full of water, but no water coming out of taps?

Just a thought , but check under the sinks there may be an inline valve that's not open, looks like a compression fitting with a slot for a screwdriver on the side.

thanks for that but there's no isolating valves fitted, there is a little water to start with but then it just stops running

Has any work been carried out?, could just be an air lock!

air lock or restriction. I'm assuming you mean hot? If you have a mixer tap or hot and cold fill w/mc you can back fill mains into the hot to try and shift it.

We have to do this on a fairly regular basis, the hot water somehow gets an airlock and won't flow.We have a mixer tap in the kitchen, and to back flush the airlock, use half a kinder egg shell, placed and held over mixer tap spout, turn hot water on first then the cold, flush for about 40 seconds, then turn cold off first followed by hot, this invariably clears airlock, and hot water will flow again.
Easier to do than explain, but it works

Hosepipe from the cold main into the tap does the same job too, in case you don't have any kinder eggs handy

I had something similar last week, got called out to a customers house who was complaining of no hot water. Unlikely to be an air lock as no work had been undertaken on that system recently and no history of airlocks.. decided it must be a blockage, and hoped it would be between the CWSC and the DHWC so popped some mains water back up the hot taps and hey presto - a little mouse popped out into the tank in the loft!... must have crawled down the ball valve to get a drink and then fallen into the tank and got sucked down the feed pipe to the DHWC!
