What's wrong?
The POL valve on 2021-2022 Bowlus Endless Highways and Terra Firma trailers is the brass propane output valve on the LPG tank. It controls the connection where propane leaves the tank and feeds the trailer's propane system. When the valve and fitting thread together correctly, the connection seals so propane stays inside the system until an appliance calls for it.
On affected trailers, the female threads inside certain RegO 901C3 and 901C5 service valves were made with thread depth below specification. That shallow thread depth prevents the POL fitting from fully seating against the valve. A connection that looks attached can leave a small gap at the outlet, and propane can leak from the tank connection.
You can notice this problem by smell or sound. If you smell propane near the tank area or hear gas escaping at the valve connection, treat that as the warning sign and keep ignition sources away.
