A bladder and attachment member assembly for use with a container comprises an elastomeric gas-filled bladder comprising a valve stem. A first attachment member is disposed over the valve stem within the container with the bladder. A second attachment member is disposed over the valve stem and over the first attachment member. The second attachment member is outside of the container interposed between the valve stem and a container opening. Rotational movement of the valve stem is fixed relative to one or both of the first and second attachment members. In an example, the valve stem comprises one or more surface features that register with one or more surface features of the first and/or second attachment member to thereby fix relative valve stem rotational movement. In an example, the valve stem surface feature is a flat surface that registers with a flat surface of the second attachment member inside diameter.

A shower system includes a shower waterway and a fluid control valve. The shower waterway is configured to be coupled to a shower device. The fluid control valve is coupled to the shower waterway and comprises a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably coupled to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a water pressure fluctuation in the shower waterway.

A deresonated fluid system may include a pressurizable fluid line having distal, opposite line ends with the fluid line extending between the line ends. A source may be configured to apply variations in pressure of fluid in the fluid line having a frequency appropriate for producing a standing wave in the fluid line between the line ends. A fluid coupler having opposite first and second coupler ends may be attached to the fluid line in a medial portion of the fluid line between the line ends. A flow acceleration ramp may be formed about an inside of the first coupler end. An artificial acoustic shoulder may be formed about an inside of the second coupler end. The artificial acoustic shoulder may define a substantially central orifice in fluid communication with the flow acceleration ramp.
