I’m embarking on a project (diagram attached) which involves taking out an old electric shower, taking out a bath, fitting new bath, then installing a gravity fed shower, with an electric pump attached.
There are bits of this I would be confident with, and would loathe to pay anyone else to do, then bits where I am all at sea. So I would rather someone just does the whole lot, and it costs what it costs. In a previous post I highlighted how it is seemingly impossible to get a plumber, so it’s now down to me.
My thoughts were to T off the pipes (under the bath) leading to the bath taps, and the chase these pipes to a shower valve.
Beyond where I have Teed off, i.e. after bath taps I would put the shower pump. As you can see on the diagram, there is plenty of space under the bath, and a power source right outside bathroom door. I figured that this would mean that the pump will only operate when shower is on, as opposed to coming on when any water is fed to bathroom.
My main question is, can you do this?. I’ve seen a well-known plumber on youtube say you can put a pump under the bath, but a supplier I enquired with says you shouldn’t do this. They also said that even if the pump is after the bath taps, it could ‘hunt, due to residual water movement in the pipes’ (?) and that the pump should be as close to water supply as possible. They are not plumbers however - and stressed that.
If I went down that route, (ie close to tank) surely the pump is going to switch on whenever water is summoned from the tank i.e. flushing toilet or using bath or sink taps? If the pump was in the attic under the cold water tank, I would need an electrician to make power supply. If the pump was in the cupboard of the hot water tank, I would definitely not be able to do this on my own as it seems that I would need meters of additional pipes to get a separate run for a shower. That would be well beyond my capabilities.
So, would my original idea work? Or am I just going to make a massive problem for myself. If the latter, then that’s fine. I just need to know where I stand, and know if I absolutely have to get a plumber. Hopefully I’m making sense. By the way, I’ve found the help on this forum so very helpful in the past, so thanks in advance.
