Two of the three hot water taps in my house splutter then die then come back
into like again in a continuous cycle within a few tens of seconds of
I have tried blasting cold water through the hot tap using a hose, and this
relieved the problem for a few minutes, but then it returned.
The header tank has enough water in it to feed the cylinder throughout.
Could air be getting into the pipes somehow?
A bit about the system:
I have a hot water cyclinder on the first floor with a header tank directly
above it - the two are combined as a single unit.
There is loads of scale in the header tank, but the pipe that connects the
two appears clear.
A 15mm pipe from the cyclinder runs to the ground floor where it supplies
three taps and a washing machine.
The kitchen sink tap is supplied via a narrower guage pipe (<15mm), and
works ok, although the flow is quite puny.
The bathroom sink tap is a 15mm tap and has the problem - this tap is
supplied via a rise in pipework of 2 - 3 feet.
The bath tap is a 22mm tap and also has the problem - this tap is supplied
via a rise in pipework of about 1 1/2 feet.
I haven't checked whether the washing machine point has the problem or not.
When the affected taps are opened part way, this does eliminent the problem
but the flow is unsatisfactory.
I have had the problem since moving in.
Any advice would be much appreciated!
