Pressure assisted plunger device with switching bellows and related methods
A plunger device may include a bellows having a proximal end and a distal end, and a handle coupled to the proximal end of the bellows and configured to switch between a first state comprising fluidly coupling an interior of the bellows to an ambient environment to permit inflation of the bellows, and a second state including sealing the interior of the bellows. The plunger device may include a tubular shaft coupled to the distal end of the bellows, and a flexible flange member coupled to the tubular shaft opposite the bellows and to be positioned within a drain so that positive pressure air flow is applied to the drain when the bellows is compressed while in the second state.
