Septic tank safety valve

Conversion kit that easily supplements an existing vent that is too small so that the tank can handle suction emptying,
as strong negative pressure can occur. No intervention in the tank is required, mounted on the hose between the toilet and the tank.
Minimizes the risk of deformation of the septic tank. The design is such that the safety valve can be placed inside the boat.
Regular venting must still be intact for the tank to be able to “breathe” normally during filling and storage.

Complete set with acid-resistant connection pipe for 38 hose (inv), 0.5 m 19 mm (inv) hose, safety valve and hose clamps.
