a) leach
b) rough
c) septic
d) grinder
Solution
The answer is the fourth one (d): grinder.
Explanation for each option:

b) Rough: This term does not refer to any specific type of pump used in sewage systems.
c) Septic: A septic pump is used in septic systems to move wastewater from the septic tank to the drain field, but it is not specifically designed for uphill flow.
