I am a recently qualified plumber and have installed an electric shower to the mains pipe, the water pressure is correct and it also has the correct fuse,when turning the unit on it runs for a second or two then cuts out, it's a creda unit, could you give me any suggestions

Hi Lee

We don't use electric showers over here in the USA, at least not yet, so I have to figure that you'll know more by far than we do.

A call to the manufacturer of the product and a quick chat with the technical department should help you solve the issue quick enough... ;)

Good luck!
