Water cylinder pump problem

[gudu]

Hello,

The pump from my hot water cylinder has started making the noise it makes when running on and off continually, even when no taps are running.

I left it for hours but it's still doing it. Turning it off and on again at the wall also hasn't helped.

I've uploaded a video showing the problem:


Does anyone have any ideas what the problem may be , please?

Is it running dry? I can't really hear it on the video

I'm not sure what you mean, I'm afraid.

The pump still works fine when taps are used but when no taps are on then it makes the constant on/off noise on the video.

Is there anything running in the vid (only ask as I can hear water running ??)

As above. Only takes a small trickle on some pumps for the pump to come on and off. Or a stuck flow sensor maybe.

The dripping is the cold water storage tank filling up. I'll have another look for any leaks any where.

Your pump may just be cream crackered

Unless you have just run some water shouldn't be dripping

Could be a leak somewhere

Had not thought of that. . #itmustbelate.

Got any dripping taps ? something like a small drip can be enough to kick in the flow sensor, or sensor is faulty, worse case new pump, is it only supplying hot water ?
