When I install 8" diameter waste or soil or storm lines I know I can use 1/16 in per ft BUT I have to use considerably less fixtures connected to this line then if I increased the pitch to 1/2" per ft

A trap on a positive drain is used to avoid the 'contaminated' air in a HVAC system from traveling through the condensate line and entering into areas where it is unwanted. The trap becomes necessary when one condensate line is used for multiple units, especially if it is tied to other negative pressure drain traps. The negative pressure drain traps may not drain properly if they have to overcome the positive non- trapped pressure of another unit. It allows the condensate to drain more evenly, as well. Without a trap, the positive pressure from the unit can blow air through the drain with the water and cause 'spitting.' A trap on a positive pressure system may not always be necessary, but it is good practice to trap every drain and trap it properly. There are guidelines for both positive and negative pressure traps. Always follow the manufacturers recommendations.

To ensure that the drainage system is working properly, the nurse recompresses the HemoVac reservoir before closing the drain emptying port. Compression of the HemoVac provides suction removal of drainage from the wound (Altman, 2004).
Most rivers east of the Rocky Mountains drain into the Mississippi River drainage system and then into the Gulf of Mexico through New Orleans, Louisiana. Some drain directly into the Gulf (the Trinity River in Texas being one) and others drain directly into the Atlantic ocean.
