Electrical Question

Shower wont come on

i had a garden hose pipe fitted to the kitchen mixer tap, and stupidly turned both hot/cold taps on, resulting in i think backflow to the attic water storage tank and water flooding the bathroom from the ceiling. since then the shower wont turn on, the pull cord is situated right at the top of the ceinling and it looks like traces of water has possibly gone into the unit?

this was about 4-6 weeks ago, how cn i get the shower to work again?

From what you desribe it very much sounds like water damage at the 45amp pull cord isolation switch. Most likely the water has corroded the copper contacts and is creating a high resistance.

Although its a relatively simple job to change the switch, you will need to register your intent to carry out this small job with your Local Building Control Department, as since 2005, all DIY electrical works in the bathroom and kitchen are fully notifiable under the building regulations.

Therefore you need to get part P consent to do the work from your local authority and pay their fee (typically around £200). Once you have got the part P consent, you can then buy a new switch, safely isolate the electricity at the fusebox and and then replace the switch.

Once the switch has been replaced, you will need to contact your local authority again and they will arrange for a buildings inspector to come out and inspect and test the work, so that it can be signed off under part P of the building regulations.

See link below for a free guide to the Part P of the building regulations or google Part P.

Of course a simpler and more cost effective way is to hire a part P registered electrician to come and replace the switch for you. As all Part P certified electricians are signed up to one of the goverments part P scheme providers (NICEIC etc) they can self test and certify their work and so it will be cheaper and quicker.
