Cleanouts in a forced main

Are cleanouts required in a forced main? IPC 2009, Section 708.3.2, does not give an exception for forced mains.

duckbill,

Typically, clean outs are not installed in force main piping, because

they are under pressure.......If you install one / some, ...how will

you ensure that the clean outs themselves will [ always ] be able to

be pressure sealed ?.......Also, recommend that you contact the AHJ

and get their input [ assuming that you are NOT the AHJ ].

Thanks north star.

The force main is 4" pvc, 1,900 lineal feet and rises about 26' with several level areas and "dips" in the design. I have reservations about the dips collecting solids. Since the IPC did not exclude force mains from cleanouts, I posed the question here to find out what others are doing.
 
duckbill:

I'd use the Ten States Standards for Wastewater. It's the main code for sewer design in the US. Available here: Great Lakes - Upper Mississippi River Board. Believe it or not it's free. Pennsylvania is a member of the board that publishes the Standard. They recommend cleanouts at low points and air release valves at high points. I'm not aware that anyone makes a pig that can clean out a 1,900 ft run of sewer.

Regards,

DB
