OK, so here's the problem I have.
I have a power shower pump installed (Watermill) which is used to deliver hot/cold to a mixer shower enclosure. The shower enclosure while we don't use them have 6 water jets, monsoon shower head, normal shower head which we do use all of which is controlled from a mixer value and a selector value. Ho, there is also a steamer which is just fed from the cold storage tank not under pump pressure. The pump is located directly off the hot water feed which was coming in to the mixer value before the pump install. Now I've had a couple of pump failures over the past three years and each time I have just swapped the pump out and we have been working once again. Now I've started to read up following what is now my third pump failure and I've found what I think may be the problem. Right now my hot feed to the pump is coming from the normal hot water pipe which is subject to air flow and as such the pump is sucking in air.
I understand that this will damaged the pump and hence this is why I'M having to keep changing them. I now understand that I need to install a flange to allow the pump feed to pull hot water without air and hence work for longer periods of time. The problem I have is that I think I need an Essex flange and this means I have to cut an hole in my hot water tank and install the flange together with a gravity loop but I simple do not have the room in the cupboard that the hot water cylinder is installed in However a surrey flange since it comes of the top of the cylinder will be an option only I have a second problem. Again due to space restrictions I can't install the pump close to the hot water cylinder and the only real place I can install it is in the loft. Now I know I now need to go for a negative head pump due to this and by all accounts these require an Essex flange and I'm back where I started.
I wonder if I can move my entire how water cylinder up into my loft or if the cold water feed would then be an issue not to mention the expansion pipe height also. Can anybody give me an option for me to sort this out?
