Someone builds a tight bay, drops the tank in, and never bolts it down because it “cannot go anywhere”.

It is designed to run unpressurized. Run a vent line from the top 1.5\" port up above the maximum fill level and out through the floor or a body vent. Skip it and the tank will deform on a hot day, then pull its walls in when the pump runs.\u003c\/p\u003e\n\u003ch3\u003eHow much weight am I adding to the van?\u003c\/h3\u003e\n\u003cp\u003eWater weighs roughly 8.34 lb per gallon, so 20 gallons is about 167 lb of payload once full, on top of the dry weight of the tank. Put that number in your build budget before you order rather than after — it is the most commonly forgotten figure in a van conversion.\u003c\/p\u003e\n\u003ch3\u003eCan I drink out of it?\u003c\/h3\u003e\n\u003cp\u003eThe vessel itself is BPA-free food-grade polyethylene, so the tank is potable-rated. What actually determines whether your water is safe to drink is everything downstream of it: the fill port, the hose, the pump and the filtration. We plumb potable systems with NSF-61 rated hose and a carbon block at the tap.\u003c\/p\u003e\n\u003ch3\u003eCan I use it for grey water?\u003c\/h3\u003e\n\u003cp\u003eYes — it is sold for either. If you use it for grey, plumb the drain at the lowest point and give yourself an outside dump valve you can reach without crawling under the van.\u003c\/p\u003e\n\u003ch3\u003eWill it fit under a bench seat?\u003c\/h3\u003e\n\u003cp\u003eIt needs 18\" of vertical clearance, which is taller than most bench seats. Under a bed platform or in a full-height galley cabinet is the usual home. Measure the height first — that is the dimension that catches people out, not the footprint.\u003c\/p\u003e\n\u003ch2\u003ePairs well with\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e\n\u003ca href=\"\/collections\/van-life-parts\"\u003eVan water tanks and plumbing\u003c\/a\u003e — the rest of the NW Conversions range\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eSold and shipped by Campervan Parts R Us, the parts counter of Noke Van Co. — a working van conversion shop in Roanoke, Virginia.
