Haven't Been Able To Use My Own Shower In Six Months

kah22

Let's try and set the facts out:

I am talking about two 'MX Duo QI (9.5kW) electric shower units, each unit only produces cold water.

The units were fitted by an experienced plumber, he updated my heating system about seven years back, when the disabled facility was been installed and he has done other work for me and my family over the years.

When the service engineer from MX called he checked both showers and said they were both working and both installed correctly. As a trial he replaced the downstairs shower (we'll asume he knew how to do it correctly) and still the same problem - no hot water, only cold water. So in all honesty I cannot blame the plumber. I've also had the electrics checked by a qualified electrician.

My water service have confirmed that both my pressure and flow exceed the minuimun requirments that they have to provide. The pressure was 2.8bar and they are required to provide 1.5bar. Don't know about the flow.

The facts are your showers aren't running as they don't seem to be getting the flow needed. Something your experienced plumber should have checked before he installed them.

I'm surprised the engineer from MX didn't immediately diagnose the problem.

Are both showers fed from the main or a tank in the loft, what diameter is the copper feeding both showers.

(Minimum running pressure must be obtained at 9 litres/minute for 9.5kW and 11 litres/
minute for the 10.5kW).

So by the sound of things your flow rate is well under what it needs to be, the numbers you stated earlier give me 6.84 l per minute.

DTDfanboy thanks for working out those figures for me. It is obvious that the flow rate is well below the required level. So the question really is what can I do about it?

I plan to do some revonations in the not to distant future which will do away with the downstairs shower. Is there anything I can do to increase the flow on the shower upstairs?

Both showers are fed from the main, sorry don't know about the pipe

Apologies if I'm been a pain in the butt

Could there be a leak in the pipework outside your home?

Well as suggested earlier a partially blocked stopcock could be an issue, can you work out your flow rate at your kitchen sink.

doubt it, the Tobby at the back door are giving good readings

The water service did fit a new stopcock outside my door so it's hardly it.

I should have mentioned it but the house is a 60's house with a larger kitchen added on at a later date.. Turn the stopcock off at my back door and you turn the water off in the original house and the disabled facility BUT not the kitchen.

Turn the stopcock off at the road and all water is turned off. So in effect water seems to be coming in via two different directions.

At this point in time it takes 120 seconds to fill the 10 litre bucket at the kitchen tap
