Question

clogging of drainage piping can be caused by any of the following except
too little slope
slopes of 45 degrees or more off horizontal
crimped pipe
foreign materials in the piping
pipe connections that project into the path of the waste
question 28
all of the following indicate leaking traps except
slow draining fixtures
staining or streaking on the trap
rusting of cleanout plugs
buckets or trays below the trap
water damage on the floor or cabinetry below the trap

Explanation:

For the first question, a slope of 45 degrees or more off - horizontal is not a common cause of clogging as it promotes better flow rather than impeding it. Too little slope can cause water to pool and debris to settle, a crimped pipe restricts flow, foreign materials and protruding pipe connections can block the path of waste. For the second question, slow - draining fixtures are usually a sign of a clog rather than a leaking trap. Staining, rusting, buckets/trays below, and water damage are signs of a leak.

Answer:

1. B. slopes of 45 degrees or more off horizontal
2. A. slow draining fixtures
