Recently purchased used 2018 Trail Runner 27FQBS. Have parked at hunting campground with no water hook up, so running off fresh water tank. Pump will run when turned on but getting no water to the faucets. No water in line on input side of pump. Could be pump but feels like there’s a shutoff closed that I haven’t found. Also not sure if relevant but understand previous owner primarily used with campground hook up. Am relatively new to RV’ing and would be grateful for any input from the group. Thanks, Dave
