no hot water from any tap in the house

Postby cath1602 » Wed Jan 07, 2009 12:56 pm

I was having a shower when the hot water cut out.

There is no water at all coming from the hot tap in the bath/shower, bathroom sink or kitchen sink.

There is a shower pump, and this does not come on.

The boiler is working ok, the central heating is ok (radiators are on), there is cold water.

Any ideas what might be going on?

Simply Build It

hi it sounds like you have an airlock on the hot water side and its possible its being caused by the pump fitting on the shower if its not been fitted with a surrey flange off the cylinder top, as otherwise it can pull air in through the expansion pipe in the roof, so get the instalation checked out first.
The airlock can be got rid of by connecting the cold mains water to the hot tap usually on the sink via a plastic hose with a tap connector on each end then you can open the hot tap then the cold and backfill the pipework until it comes out of the expansion pipe then it should get rid of all air

Yes, that seems to have been the problem.

I have a mixer tap on the bathroom sink and I was able to force cold water into the hot side by blocking the tap. I will have to look at the shower pump and see if I can do anything to avoid the problem in future, but for now I am sorted.

Thanks very much.
