WHAT IS AN EXAMPLE OF CLEAR-WATER WASTE?
WATER DISCHARGED FROM A:
1. DRINKING FOUNTAIN
2. COOLING JACKET
A cooling jacket, also referred to as a flow generator, ensures that there is always sufficient water flow across the motor surface in order to cool the motor. In a typical well installation, the pump is surrounded by the walls of the well. The motor is installed below the pump.

What's the difference between wet and dry venting?
A wet plumbing vent drains water from one fixture while ventilating the air, among other fixtures. On the other hand, a dry vent only transports air and does not carry water. This is to say that wet vents may drain one fixture and vent another, whereas dry vents typically vent air from a single fixture at a time.
