It is not simplistic to give standard solutions for any system, nor must every house be considered the same as another house, the variables are different, sometimes undersized pipes and accessories involve choices of systems that lead to a considerable increase in water pressure in order to satisfy the utilities, or utilities with double or triple services involve the use of pumps with high flow rates. In any case, the various technical solutions must be well identified, he knows the house and the route of the pipes well. It is very difficult for me to answer you
