can anyone tell me if it would be okay to take a hot feed for the pump from the main
hot pipe that feeds the rest of the house.
i know it should have its own feed from the cylinder but my cupboard is tiny and i cant see where a new pipe would fit in. i am having to fit the pump in the loft below the cold tank. HELP.

The shower pump should be fitted at the base of the H/W cylinder and the hot supply should not be teed off the present hot supply. You need to change the 22mm outlet on the top of the cylinder to a surrey flange which gives 2 seperate outlets for hot water and run the side outlet to your pump. The cold for your pump should come direct from your cold tank in the loft indepentently.

Shower pumps need to 'push' the water rather than 'pull' as you are hoping to do.

I am not an expert in shower pump installations. I only know the basics which you appear to know but cannot install to. Perhaps another on here can advise you better icon_wink.gif

Is there any other space, under a bathtub, for for instance, where you could install the pump?

(That should get the electricians doing somersaults! icon_smile.gif )

yes, you can fit at the base of the bath,(not sure about electrical regs) or above the cylinder, keep it as close to the cylinder as can be, follow ALL of the remarks Gas 4 You made, bear in mind you need a minimum flow rate to operate a standard pump, this means follows all Mi's, and clearances from base of C/W tank and highest outlet icon_exclaim.gif
