Electric shower problem


Hi

I have an electric shower which is playing up.
Whenever I turn it on water comes out of the pressure release hose and also leaks out of the main casing. The only way to stop it is to remove the shower head. This led me to believe that the shower head was scaled up so I descaled it but the problem persists. Related to this is that when the shower head is removed the water that comes out of the hose contains small flakey particles.
What I think is happening is that these particles build up inside the shower head causing the backward pressure, BUT, what is causing the particles in the first place?
The shower is at least 8 years old, more likely 10 years.

Thanks
Matt

I suspect the flakey particles are from your water heater. This usued to happen 10+ yrs ago but we all thought they had fixed the problem, now it seems to be back. In the water heater, under the cold water inlet is a plastic tube that directs the cold water to the bottom of the tank, the heated water comes off the top. The tube is disintegrating, which is where the particles come from. Also, it will seem the hot water is running out quickly, because the cold is now diluting the hot water at the top of the tank. Replacing the tube is fairly easy, but getting all that stuff out is harder. If the heater is older than 8-10, it might be better to replace it.

You will have to clean out all the faucet aerators, since they will become clogged also.

An electric shower....interesting. I've never seen one, but I'd guess the electric part is a small instantaneous water heater dedicated to the shower alone. Interesting indeed.

The small flakey particles could be calcium buildup in the piping of the unit. Since you mentioned a hose I assume you have a handheld spray wand. Did you only clean the rubber nozzles and the faceplate of the shower wand (head) or did you also disassemble and clean the spray plate assembly and the nozzle ring. If not, there could still be a buildup internally. I'd run the water awhile through the hose without the showerhead installed to remove as much of the foreign material as possible and clean everything again. If none of that works I'd start looking at the shower control unit itself.

Blimey - I guess plumbing in USA & UK is quite different if you guys haven't heard of an electric shower. Check here: http://www.tritonshowers.co.uk/electric-showers.aspx

And what is 'city water & well water' ?

Anyway, I reckon the problem is limescale build up in the element which is getting into the water as it passes theough so going to order a new shower.

Cheers!

Well water comes from ground water. City water comes from a city source.

The electric showers are quite common in some areas of the world
I think you stated the problem correctly
Not sure if that can be dissasembled & cleaned
If you are buying a new one anyways I think I'd be inclined to take the old one apart after to determine the problem & possible cleaning
One idea might be to disconnect it & run some vinegar thru it (no power)

yep the USA and the UK must have quite different plumbing systems. Here in the states, if you told someone to go jump in an electric shower they'd tell you to go get @#%$ed! We try to keep our electric and our water separate for safety reasons. lol

Good luck!
