A method for depressurizing a pipe includes forming, by an ejector assembly, a seal between a first pipe and a second pipe fluidically coupled to the tee pipe fitting. The first pipe flows a first fluid at a first pressure, and the second pipe flows a second fluid at a second pressure lower than the first pressure. The ejector assembly includes a nozzle converging along a flow direction of the first fluid flowing in the first pipe, and a mixing chamber at an outlet of the nozzle, the mixing chamber comprising an outlet is in fluid communication with the second pipe. The method also includes flowing the first fluid from the first pipe into the ejector assembly through the nozzle so that the pressure of the first fluid decreases to a third pressure lower than the second pressure to draw the second fluid into the mixing chamber.

A dual-levered faucet assembly which allows user to reduce water usage by 50% when needed while operating the faucet in habitual preferred manner of using swift single motion of hand. When any one lever is operated in this manner, the water outflow is 50% of a conventional single-levered faucet. When both levers are operated in this manner, water outflow is same as that of a conventional single-levered faucet.

A gas-fueled heater can have a housing with pressure regulators, a control valve, a fluid selection valve and a burner positioned therein. The pressure regulators, control valve, fluid selection valve and burner can be configured to combust a fuel to create heat. The housing can include a number of holes passing therethrough to control access to the various components.
