Increase pitch or increade piping diameter
Radio Shack "drain pipe tracer".
Screw in clockwise to increase pressure, has nothing to do with volume. Volume can only be increased by upsizing the pipe diameters. That's why it is called a pressure reg., not a volume reg.
To effectively repair a drain pipe using a drain pipe repair sleeve, follow these steps: Clean and dry the damaged area of the drain pipe. Slide the repair sleeve over the damaged section of the pipe. Tighten the clamps on the sleeve to secure it in place. Test the repaired pipe to ensure there are no leaks.

Yes, a sewage drain pipe can be too large.
It depends on how much water was in it to begin with and how much water is entering per minute.
If you are talking about a roof water drain pipe to sewer it is illegal. If you are talking about a sink drain pipe well that is where they all connect to so yea.
you cant decrease a pipe diameter you can only increase...
A French drain can typically handle around 12-15 gallons of water per minute. The capacity of a French drain is determined by factors such as the size of the drain pipe, the slope of the drain, the type of soil, and the amount of rainfall in the area.
dvw pipe = drain, waste and vent pipe.
The volume of flow will be the same, but the velocity will be increase through the 15ml pipe. Q=v*A.
If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
