Attic bathroom pump placement

[CLC plumbing]

Looking for some input here from the experts.

I’m having an issue with my pump. I thought I’d get away with a positive pump as I put it beside the cylinder. I’ve run all the bathrooms off it but the attic bathroom won’t work as the faucets are above the tank head. I wonder if I change the pump to a positive will it run both the main bathroom as well as the attic even if it’s beside the cylinder? Will a negative pump work with both positive and negative pressure?

Yes a negative head pump will work with both situations- in fact some manufacturers now refer to this as a universal pump to emphasise this fact.
