No not sniping just finding (as others who have bowed out) your posts increasingly confusing.  To be helpful, as you seem to be having difficulty in explaining your problem/system succinctly, I suggest you get a plumber in who will be able to practically assess, and hopefully fix, the problem.  Again no need for sarcasm - its not clever

Theory behind non return was that maybe pressure would reduse in the pipe as the hot water cooled. Suction would withdraw the water from the tap end, so was less likely to start to flow.

I never said it was a good idea just a desperate one while plumber was here for the last boiler service.

Right. No legal requirement for it so bin it

I wonder if there is another one on the pump if so bin that one as well

Just to be clear(er) the downstairs loo tap cold in the video is also connected to the pump, and flows fine.

In order to get the kitchen tap to flow, leave it open, turn on any other tap in the house or indeed if a loo has been flushed or anything that does cause the pump to turn, then the kitchen hot will flow. Because the tap is open, and the pump is now turning, due to the cold tap turned on as in the video, then the kitchen hot tap flows.

How come the pump pumps hot and cold water? been following this, seems to be the strangest set up - ever.........

originally, because the flow to the tap/shower mixer was so poor. Flow to all other taps in the house where poor too, although not as bad, so it was later altered to pump all pipes, except kitchen due to the water softener.

So one pump pumps hot and cold water, surely that would give you warm water at all outlets......or does the pump have multi vanes?  I think Michael 2.6? was trying to clarify a few things and descriptions may be differing, hence confusion.......

Its a twin. Think pump, in the middle, with a cold in and out on one end, and a hot in and out at the other. If it detects flow at either end, the pump chimes in and pumps which ever tap or outlet is on.

Right, that reminds me of the 'Startomatic' generators I used to work on years ago....

So pressure or a low voltage sensor should turn on your pump, got my head round this now, but not familiar with it, sounds like it has never been working properly.......

[chrisgixer]

The tap has never been right. The pump works fine.

The bathroom tap is also a mixer but has a separate tap for hot cold. Works fine.

[chrisgixer]

Pump is like this.

Can you try a different kitchen tap or if you have isolator valves under then try connecting straight the hot pipe with a bit of flexible tubing into the sink. If when you turn on the isolator valve, the pump starts and hot water flows, then this shows that there is not enough initial pressure released with the tap to start any flow, so you get a pressure drop to start the pump.

Personally, I think the only solution will be to replace the tap for a low pressure one.

Here are a couple of links that you might find useful. You tap appears to be in a grey area between a low pressure 0.3bar and high pressure 1.0bar

http://www.tapstore.com/identify-your-plumbing-system

This link describes your system except for a shower, but it explains why a non-return valve should be fitted and why this will make the pump less likely to turn on.

Finally, a variation of the above with all house with hot pumped, but the same problems as above.

There are isolator valves for the washing machine on the same pipe iirc. But I'd need to check. If so, wmc has no problem with hot flow.

[Rods2]

Looking at your pump specification. this is surely the problem "Flow switch sensitivity: approx. 0.6 l/min", you have no water flowing at the tap, so you don't get the 0.6l to start the pump.

If the washing machine has a hot supply as modern ones don't, so they can get an "A" efficiency rating. This is madness, but rules are rules.

[chrisgixer]

Yes, so how to get it working? It is high pressure approved. Although ours is pumped gravity feed. Not entirely the same I know.

We want to keep the tap. Or she wants to keep the tap, put it that way.
