Refits are where the Ronco Plastics B149 earns its keep. When a 30-year-old aluminum water tank finally pinholes, the replacement has to thread through an existing hatch and land in a compartment built around the old tank - and a 22 gallon polyethylene molding with a 30 lb ship weight is the kind of part that actually makes that trip. Check the B149's outline in the drawing below against your opening before anything else; if it passes, the hard part of the refit is already over.
The tank comes from Ronco's Tustin, California plant, molding marine tanks since 1974, and follows the line's signature workflow: fittings installed per order, spin-welded or threaded where you mark them. That lets you match the old tank's port positions so existing hoses reconnect - or fix the old layout's mistakes while you are at it. The fitting planner on this page captures the plan.
In potable service the polyethylene is FDA compliant and tasteless, and unlike the tank it replaces it cannot corrode. Full weight is about 183 lb of water, so reuse or rebuild the old tank's chocks accordingly. More sizes wait under boat tanks and the whole catalog at the Ronco Plastics hub; the freight estimator prices the ship to your ZIP. OneSource Plastics is an authorized Ronco Plastics dealer.
