When I turn hot tap on up stairs water comes out of hot tap downstairs.

[Teddysam154]

[FONT=&quot]I wonder if any one can help me. I tried asking about this on another forum on another website and just got abuse and name calling. I am not a troll this is a genuine problem and need to know how to fix. I know it sounds like a impossble problem but is happening. I live in a rented house. I went to run my children a bath tonight I turned on hot tap[/FONT][FONT=&quot] and heard a screeching sound coming from kitchen downstairs and the sound of water.[/FONT]
[FONT=&quot]I went down stairs to check and the hot tap in kitchen was screeching and water was coming out of hot tap even though it was turned off. [/FONT]
[FONT=&quot]When I turn off bath [/FONT][FONT=&quot]hot tap up stairs hot kitchen tap down stairs stops screeching and water stops coming out. But as soon as I turn bath tap back on kitchen tap starts screeching again and water comes out again.[/FONT]
[FONT=&quot]What could be the problems. And[/FONT][FONT=&quot] how can I fix. It seem very odd.[/FONT]

[FONT=&quot]I don't know if it is relevent but thought I should mention we have had some problems with heating system loosing pressure. It was fixed but a month ago we had boiler serviced and day after boiler lost pressure and had to be re pressurized.[/FONT]

[FONT=&quot]We have a combi solar power boiler. Dont kn[/FONT][FONT=&quot]ow if this helps[/FONT]

[FONT=&quot]Any advice much appreciated[/FONT]

[FONT=&quot]Thanks in advance.[/FONT][FONT=&quot]

Sorry forgot to say water does come out of bath tap as well when turned on. So when I turn bath hot tap on water comes out of that tap and kitchen tap down stairs at same time even though kitchen tap is turned off. I just don't understand it.

I would suggest the drop in pressure when you open the upstairs tap is causing something to relax in the tap downstairs allowing water to pass. Maybe the tap gland or the washer. It would sound like something is not well in the downstairs tap so maybe replace that/get your landlord on it

That's a mighty brain wave Riley.

To the OP , Are these quarter turn taps down stairs or screw down (normal)

Can happen with ceramic disc taps, when the pressure is reduced. Eg, when opening a tap. Fitting mon return valves on the hot and cold supplies to the tap stops the problem.

can happen with too much pressure, prv stops it

Have you got the Alpha SolarSmart 90, the boiler with the solar cylinder ?

I believe they are quarter turn taps so have the ceramic disc return valves. I'm going to take tap apart in the. Morning to check for sure. If they are do you think replacing the ceramic disc return valve will fix the problem.

Thanks again for all your replies you have all been very helpful.

Boiler is a alpha it says on it gas saver and model number CD25X. I don't know if this means any thing. There is a water tank next to it with a tiny circle screen in bottom corner that lights up and shows temperature of water in tank. There are pipes that go up to the loft to the solar panel on roof.

Don't knoiknoiw if any of this helps

Yes that sounds like a SolarSmart system, it was defiantly hot water coming out of the hot kitchen tap ?

It is just that your system will have a thermostatic mixing valve on the hot water outlet pipe work where cold water can mix with hot water & so it is easy to get an imbalance of pressure.
