Plumbing Vents
Does anyone know where I can get a tank & plumbing vent diagram for a 2019 Bighorn 3760 EL??
Also, anyone know why plumbing vent pipes to the roof vent would move? Like upward forcing the vent caps to break loose??
Hi Jack,
Cant help you with a vent diagram ( I am sure the factory can) your vent stack to the roof is not secured properely. When you are underway the tank with contents moves as you travel. This may cause a loose vent stack to rise and fall. Securing it with the vent pipe protruding into the tank 1.5" (no more as you will loose tank capacity) then securing the vent pipe so it cannot move between the tank and roof is critical for proper venting.
