Toilet/shower block pressure problems?

[Illuminate]

Where I work we have problem with the hot taps pressure and temperature is quite poor. Apparently it has been poor for a while but was once much better. It is a commercial setting toilet block which is gravity fed from commercial sized tanks. The taps are mixer taps and mixer showers and I believe but I don't know for sure that the hot and cold supply are both from the tanks. I have not checked the set up yet and I don't fully understand plumbing to this scale. The system is pumped and I assume the pump works as other more experienced staff believe it is.

I am aware of airlocks but is this something that can occur in this large size system or more common in domestic settings.

Someone said to me that they think the problem started when the place opened again after being shut a while during covid restrictions.

Any ideas or advice welcome.

Thanks

High pressure taps on a low pressure system if you can best switch to individual taps

Are all mixer taps high pressure and at first apparently the pressure was good but with the wrong taps would this be the case but just deteriorate quicker?

Thanks for your help
