Electric shower query

Searcaigh · Oct 14, 2018

Spark just put in a electric shower (Triton) and hit a small problem, black brick wall behind the tiles where he wanted to install.

He said not to worry, he will just trunk it up into the ceiling (which goes into the loft). To do this, he cut a hole in the top of the shower box. He hasn't sealed the hole, there's a rough 0.5cm to 1cm gap between the hole and the trunk, and the trunk isn't flush or sealed against the tile wall.

Looks like water could very easily splash into the inside of the shower box through these gaps. Is this safe? I am going to seal it myself but want to know if this could be a serious issue or not as he left it.

Thanks for your time.

Hi and welcome to the forum. Do you have a picture that you can post as that will help? Is this a new circuit and new shower or just a replacement shower and did your electrician provide any certificate for the works that he carried out? I assume that the shower was fitted in a domestic property?

Some showers have an internal 'channel' for top entry as a cable route which diverts water away from where it shouldn't be. Having said that it doesn't sound 100%!

Hi - yes a few pics will help

.
There are entries designed to be cut out in the top, but what we can't say is how well that's been done.

Thanks for the replies!

I've attached some pics.

Inside the trunking is the water pipe and the electric wiring. He didn't feed anything into the wall as its black brick then into the master bedroom.

It looks like he has used a tool to cut the hole required, the edges are rough and hopefully you can see no attempt to waterproof the hole was made.

That's not pretty is it?

Have you paid them? If not politely ask them to return and do it properly before you part with money..

To answer some other comments:

We have RCD in the flats fuse box.

There was no electric shower in place before, but the circuit was there. The pull chord for the on/off for the shower was in place and now serves the new install.

What did he use his teeth?

Looks a mess. Did the 'electrician' provide any certificate?
Is the plastic trunking simply stuck to the wall or screwed as well?

Searcaigh · Oct 14, 2018

No certificates supplied. Its a residential flat.

The trunking appears to be stuck to the tiles.

Did he arrive on a horse? That’s appalling. He has negated the IP rating of the shower.
Water will get in, it will cause problems.

I really hope you haven’t paid him.

Searcaigh · Oct 14, 2018

Thanks again.

He's the spark my landlord uses. So I am not sure about payment.

Can this be remedied with silicon? Just predicting what the spark or landlord might suggest.

First of all, please DO NOT use the shower until you are 100% sure it’s sealed and safe to use. Was the electrician you used a member of a competent persons scheme?
