Hot Water





Hot Water
When I turn the hot water on it flows, trickles, and stops after 20 seconds – what to do?

When I turn the hot water on in bathroom or kitchen it starts flowing (warm) then in a few seconds it slows dows and stops altogether. I have a cold water tank in the loft, a hot water one in the bedroom, and a central heating gas boiler in the kitchen. The pipework has been recently replaced by a friend. Cold water is fine. I don’t understand how the two tanks and the boiler work together? The radiators work just fine, why doesn’t the hot water work? We tried airing the tank by connecting the hot and cold water pipes in the kitchen and letting the pressure from the mains push whatever bubbles there were out through the system but we still have no hot water. With an eight weeks old baby in the house this is a disaster – please, help!
I forgot to add that the pipes are copper (mostly new ones), and the taps in both kitchen and bathroom are all brand new.

My first thought would be a leak that only drips (releases pressure) when the pipes expand from the heat of the water. If you’re using something other than copper, than I couldn’t tell you. I would suggest calling out a plumber and making sure your friend didn’t screw things up.

BTW, the cold and hot lines have separate pipes, so even if the hot doesn’t flow, the cold would.
