water is leaking behind this
It has a rubber seal around it all and was attached to the tiles with silicone from 7pm to 5pm on the back of the plate
The rubber seal is probably doing nothing and the silicone had failed.
When I re-attach, what is the best way? same as it was?. Is there much point in using the rubber seal? Anything stopping me from using silicone on the outside 7pm-5pm instead/as well? seems like it would be be better water proofed. Not overly fussed about looks the shower doesn't actually look like the above, its a 20 year old triton.
should I silicone round the faucets too (from the back)?
