I just had one fitted and noticed the connections are 15mm , afaik most of my plumbing is 22mm with 15mm branches for sinks and showers , will that meter reduce my flow rate or pressure?
I just tried the shower and flushed the loo and the flow dropped off in the shower but tbh I’ve never tried that before so I’m none the wiser
