Plumbing device

A method of assembling a fluid control device having a housing with an inlet and an outlet with a flow passage therebetween, the housing including a first body and a second body, the method comprising:

• inserting a fluid control mechanism into an upstream end of the first body, the fluid control mechanism including a pressure regulator and a piston biased by a spring away from the pressure regulator, the pressure regulator having a downstream end of the first body and defining an opening to allow fluid to pass therethrough, wherein, when fluid pressure is increased in the fluid control device, the piston is forced towards the pressure regulator;
• connecting and sealing the downstream end of the first body to an upstream end of the second body forming a cavity therebetween, the cavity having a lateral opening,
• inserting a check valve into the upstream end of the second body;
• and
• inserting a stop valve into the downstream end of the first body or the upstream end of the second body such that a handle mechanism for the stop valve extends through the lateral opening.

A plumbing device comprising:

• a body with an inlet and an outlet, the body having a first portion and a second portion;
• a pressure regulating device defining an opening to allow fluid to pass therethrough;
• a piston biased by a spring away from the pressure regulating device, wherein, when fluid pressure is increased in the plumbing device, the piston is forced towards the pressure regulating device;
• a backflow prevention device;
• and
• a flood prevention device;
• wherein the first portion of the body is connected to the second portion of the body, the first portion of the body housing the pressure regulating device, and the piston, the second portion of the body housing the backflow prevention device and the flood prevention device being housed by the body between the first and second portions.

A method of assembling a plumbing device, the method including the steps of:

• retrieving a housing having an inlet, an outlet and a flow axis extending between the inlet and the outlet;
• housing a fluid control mechanism in a first part of the housing, the fluid control mechanism including a pressure regulator and a piston biased by a spring away from the pressure regulator, the pressure regulator defining an opening to allow fluid to pass therethrough, wherein, when fluid pressure is increased in the plumbing device, the piston is forced towards the pressure regulator;
• and
• housing a flood prevention device in a second part of the housing, the fluid control mechanism performing a different fluid control function compared to the flood prevention device;
• wherein the first and second parts of the housing are configured to be connected together such that the fluid control mechanism and the flood prevention device are located along the flow axis.

A fluid control device having a housing with an inlet and an outlet with a flow passage therebetween, the fluid control device comprising:

• a first connector at the inlet;
• and
• a second connector at the outlet;
• the housing comprising:
• a first body formed as a single piece, the first body including the inlet at an upstream end thereof and housing a pressure regulator to regulate flow in the flow passage and having a downstream end;
• a second body formed as a single piece, the second body having an upstream end, housing a check valve to prevent back flow through the flow passage, and including the outlet, the downstream end of the first body being connected and sealed to the upstream end of the second body forming a cavity therebetween, the cavity having a lateral opening;
• a stop valve within the cavity to selectively block flow through the flow passage, wherein the stop valve incorporates a flood prevention regulator;
• and
• a handle mechanism for the stop valve that extends through the lateral opening;
• wherein the stop valve has a pressure release aperture in fluid communication with the device outlet when the stop valve is closed causing, in use, a pressure reduction across the flood prevention regulator allowing the flood prevention regulator to be automatically reset by closing the stop valve.
