    Pressure won’t build up, it will be let out by the pressure relief valve and make a mess on the floor. Which is also undesirable.

      Well, right up until the pressure relief valve fails. Whether it fails open or closed, you’re gonna have a bad time, because either way you’re probably going to have a lot of water where there’s not supposed to be water.
