Claims6
A method of operating a fluid purification device, comprising:
- biasing a relief valve into a non-operational position, the relief valve providing a fluid path between a hollow interior of a tank of the fluid purification device and an exterior of the fluid purification device, the relief valve having a valve member and a cup portion arranged at an end of the valve member within the hollow interior, the cup portion including a recessed area on one end and a first seal on an opposite end, an opening of the recessed area facing the hollow interior of the tank;
- transforming the relief valve to an operational position wherein the first seal is in sealing contact with a surface of the hollow interior of the tank in response to the tank being filled with a fluid, wherein a portion of the relief valve is positioned within the hollow interior in both the non-operational position and the operational position;
- pressurizing the hollow interior during operation;
- de-pressuring the hollow interior;
- and
- unlocking a cover in response to moving the relief valve to a released position.
