We installed one for the house dropping pressure to 75PSIG. I hadn't installed one on main line to yard hydrant because plan on extending run another couple hundred feet.Definitely need a pressure regulator. 100 PSI is higher than you need for anything shy of pressure washing and there are machines for that. I'm surprised you don't have a regulator coming in from the (I am assuming) city feed line. You don't want that sort of pressure in the pipes in the house either.
