Replaced shower, no cold water.

[Stuart Grimshaw]

I've just fitted the replacement shower that I've been sent and while there is some cold water coming out now it's not constant and ebbs and flows. It almost feels like there's not enough pressure to keep the shower supplied? Could that be right? I've replaced a non-thermostatic Mira Event XS with a new Thermostatic one. Could the motor just be more powerful now? Drawing more water?

I'm just letting the header tank fill before I try and turn it on again.

Absolutel nothing to do with that, the pump literally only requires inches of height/head from the CWST, as I asked before when you slacken the filter housing ENSURE that HOT (feel it) water flows out of the RED marked filter, and obviously cold from the blue marked filter.

I’ll check first thing in the morning,

This is a video of what’s happening.

Thanks for your help so far John, it’s very much appreciated.

Sounds like it's full of air.
