Outside, I just finished pouring an 8x4 slab, and ran 16 feet of electric into junction box, capped off. Initially, i pour slab for heater, and waste bin or out door shelving, overlooked the pump situation. I do have 2 pumps that was used with it, but i think that would be over kill on water pressure. Maybe a small pump, i believe it was 45 - 107 F on the settings, which is fine with me. I have to run out to the storage shed, and check on those pumps. The noise will only bother its self, its more of a guest house/work shop/man cave/gaming room game days are loud, and workshop equipment throughout the week
