MegaFlo and Power Shower

[GeoPlumbing]

Hello
I have a client that wants a 210 Direct un vented Megaflo installed although they have a power shower (Aquastream) in the bathroom.
I do know power showers are designs for low pressure systems. would the power shower unbalance the hot and cold system possible causing air to form within in the pipe services?
Any advice on this subject would be appreciated.

No, the power shower has an integral pump and this will no longer be needed and it will kill the pump if used. Has to be replaced im afraid.

Pretty basic stuff this. Are you G3 qualified?

I was wondering if we could get G3 tags on our names?

Hello Thanks for the reply... Yes I did advice the client that he'll need a high pressure thermostatic shower mixer, to replace the power shower. Although He recieved quotes from 2 other plumbers who insisted he leaves the power shower as it is while also having a Unvented cylinder installed.
Thought I was going crazy...
