We've just a new shower fitted using a Salamander CT50+XTRA pump with a rain shower head and an ordinary shower head controlled with a diverting valve.
We have a gravity fed cold feed from the loft and the hot feed comes from the immmersion tank via the surrey flange that was fitted by the plumber.
If we use the 'ordinary' shower head all is fine, however if we switch to the rain shower head it works until you increase the temperature at which point after 30 seconds or so the pump shuts off and we get no water.
The pump is rated at 1.5 bar, so my question is, if we upgraded the pump would this help? or is there potentially something else going on?
Thankyou in advance, J
