How to fit an electric shower

Recently our electric shower started playing up it would struggle to keep pressure for water coming out and then in its last few days it would shut down. This happened over the space of a month and it was a Mira Advance 8.9KW electric shower. there was a manufacture date on the inside of the shower and it was made in 2003 september some time i think so even if it wasn’t used until 2004 then its had 7 years of useage which i don’t thinks bad really

First thing i did was turn the power off to the electric shower from the consumer unit downstairs. Next was the water isolation valve in the cupboard behind the shower.

I now felt slightly safer even looking at the shower with the lid off.

Our shower lid / front bit seemed loose and had no screws holding it in place. Be careful when you remove the front as it often has a cable leading to the main unit.

I unscrewed the screws which where keeping the 3 cables in place. i then straighten the cable out to make it easier to remove the old unit.

Now for the water pipe, depending how old your shower is it maybe a push fit connection which is pretty new and requires no tools. Or a older style compression fitting which will require spanners to loosen.

The only thing left now are 3/4 screws which are holding the actual shower to the wall. You may need to do some jiggling to loosen the water pipe off but apart from that there’s nothing holding the shower on.

Our new shower is a Bristan Joy 9.5 KW we bought it from PTS a nationwide trade place.

Now our water pipe comes in through the bottom and yours maybe different but, all i needed to do was remove the old compression fitting from the pipe Inc the olive this bit looks like a copper ring. This is the bit where i got stuck as i put my pipe into the push fit connection, as i needed to mark new holes. But i then couldn’t get the pipe out of the push fit connection so ended up turning the shower unit round on the pipe which i wouldn’t recommend. I drilled the holes and put it the supplied plugs but in hind sight i would use your own brown or red plugs as the provided ones where shit.

I then screwed in the electrical cable from the bottom of the unit, attached the front panel cable then placed the front panel onto the unit and screwed in.

All you need to do now is turn the water back on and then the electrics.
