Device for troubleshooting, testing, and removing blockages from presssurized sewers

A method of troubleshooting, testing and/or removing blockages from low-pressure sewer systems comprising:

• providing a source of pressurized fluid;
• providing a device comprising:
• a first coupling for connecting to a source of pressurized fluid;
• a controller for regulating pressure of the incoming pressurized fluid;
• a flow meter downstream of the controller that meters and totalizes fluid flow;
• a pressure relief valve downstream of the flow meter to protect against an over pressure event;
• a check valve downstream of the pressure relief valve for preventing fluid backflow;
• a pressure gauge on the backside of the check valve to measure system pressure for monitoring the pressure delivered to a host pipe of the LPSS for the duration of the event;
• a dump valve downstream of the pressure gauge for relieving any remaining pressure between the check valve and the host pipe of the LPSS;
• and
• a second coupling connected downstream of the dump valve;
• connecting the second coupling to an LPSS;
• and
• manipulating the controller to provide a particular pressure to the second coupling.
