There is a switch immediately to the left when you enter the trailer and when on sounds like a pump? air compressor? (very loud!). There was a 12V pump in one of the cupboards so I am thinking previous owners may have pressurized their system with it? Any tips on how to troubleshoot or even know what's there would be awesome. Super new to this!
