This isnt the exact shower but looks a lot like it, there is no makers id on the shower.

I have been asked to sort a shower problem out. Customer had garage converted to a new bedroom with en-suite shower.

Builder has laid all pipework under concrete floor and then hidden behind shower tiles.



From what I can gather feeds for shower are taken from washing machine feeds, so mains cold, tank fed hot.

The problem is the valve is letting the cold water by and over flowing the cwsc via the hot expantion pipe. They had insurance company plumber come out??? who said the valve is knackered.

As this is in the garage ther is no direct way of getting either dedicated mains feed for new elctric shower of cold/hot tank fed for shower pump.

Any ideas chaps.

Any ideas chaps.

What is the question?

Shoot the builder

 

[Rico99]

Sorry guys,

Completely missed out the actual question.

How do I stop the water getting back through the shower on the hot side.

And do you think the shower they have will still work or do I need to get a new one.

Youll have to replace the innards or the whole shower but its not good that its been taken from the W/M pipes !!

Thanks Gasman,

I cant see for sure but I think he will have teed into the copper supply pipes.

Does this sound like I will either have to fit a non return valve on the hot supply or just get a shower with one built in.

It will restrict the flow with non returns so if you do put em on both to even the pressure,, is this a combi boiler or cylinder?

 

[Rico99]

Mains cold / cylinder hot

You cant have a shower fed with 2 different pressures

the hot will have to be pumped or a cold will have to be brought down from the tank in loft..
