Fitting a new cylinder to my vented gravity fed system. Plan to fit a shower and bath and get rid of electric shower and wetroom. I am concerned my pump will not be able to handle it if I run bath very hot as no cold will come through via diverter valve so twin input pump will not be running cold, just hot. I have positive head shower. I only want 1.0 to 1.5 bar pump. Have you a pump for this? Thanks.

A monsoon pump would be ok for filling a bath. Although it's not ideal running the pump one ended, it will only be for a few minutes and a brass pump will cope with it better than a plastic pump. We have a Monsoon 1.5BT that would be suitable.

As long as you have a flow of at least a litre per minute under gravity, hot and cold, you can use a Standard (positive) pump.

I would suggest fitting the new equipment before purchasing the pump as some diverters are quite restrictive and may require a Universal pump.
