Secondary containment or diversionary structures are required for underground piping to prevent releases to navigable waters and adjoining shorelines and to capture the discharge of oil until cleanup occurs.

When the supply tank is pumped down, the pump shuts down to.
The example shown below, with the pipe almost touching the floor, will impede the water flow and cause it to splash upwards. Again, for safety of anyone nearby when it goes off. The discharge pipe should be the full size of the compressor outlet or larger, and it should run directly to the aftercooler if one is used. Not be directly connected to the drainage system.

Unnecessary pockets should be avoided. P2803.6.1 requirements for discharge pipe. The rationale for not requiring secondary drainage is that if positive drainage is provided, that is adequate to drain the roof. Make a preliminary selection of nominal pipe sizes in inches for discharge, liquid, suction, and hot gas refrigerant lines from tables based on nominal compressor tonnage.
Discharge pipe shall discharge independently by gravity through an air gap into the drainage system or outside of the building with the end of the pipe not exceeding 2 feet (610 mm) and not less than 6 inches (152 mm) above the ground and pointing downwards.
The type of fixture determines the size of the discharge pipe and trap, and the size of the discharge pipe determines the minimum gradient required for the pipe: The outlet of the discharge pipe shall terminate within 6 over the floor or receptor, but not less than a distance equal to twice the diameter of the outlet pipe. Be installed to flow by gravity. Water must not be allowed to discharge where it can cause structural decay.
Icc digital codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures.
Terminate not more than 6 inches (152 mm) and not less than two times the discharge pipe diameter above the floor or waste receptor flood level rim. Not be directly connected to the drainage system. Pipe and fittings shall be the same size as, or larger than, the pump discharge tapping. Finally, the control elements of the system consist simply of an on/off control for the pump.
We will vary the pipe diameter to demonstrate how a change in the pipe diameter affects the flow rate through the system.
1:40 for pipes 65 mm diameter and under. The discharge piping is considered to be the piping between the compressor and the aftercooler,. Not be smaller than the diameter of the outlet of the valve served. Not be smaller than the diameter of the outlet of the valve.
No steam pipe shall be directly connected to a plumbing or drainage system, nor shall water having a temperature above 140°f (60°c) be discharged under pressure directly into a drainage system.
Discharge to a termination point that is readily observable by the building occupants. Water flow (gpm/gph) based on. Discharge through an air gap located in the same room as the water heater. Terminate not more than 6 inches (152 mm) above and not less than two times the discharge pipe diameter above the floor or flood level rim of the waste receptor.

Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap.
The discharge pipe must terminate close to the floor level to prevent harm to building occupants. Exception #1 of section 1511.1 states existing roofs do not have to meet the requirements of the code if positive drainage is provided. Guidelines concerning these valves and their discharge pipes reflect real hazards that every homeowner and home inspector should take seriously. Discharge to a termination point that is readily observable by the building occupants.
Terminate not more than 6 inches (152 mm) and not less than two times the discharge pipe diameter above the floor or waste receptor flood level rim.
That said, we put together the following tables to serve as general guides for estimating a pipe's water flow capacity through a pipe or roof drain.
