2026 QUESTIONS AND SOLUTIONS
◉ zeolite. Answer: A substance used in water softening which
exchanges sodium ions for magnesium or calcium ions in hard water.
It is regenerated by passing brine through it which reverses the
exchange.
◉ aeration. Answer: best treatment for removing taste and odors
from water
◉ aeration
granulated activated carbon filtration
ozonation. Answer: treatment for taste and odors of water
◉ deionization. Answer: process wherein water passes through a
cartridge where dissolved mineral salts are retained producing
mineral free water
◉ granulated activated carbon. Answer: a type of neutralizing filter
◉ angat dam. Answer: supplies 97% of water needs in metro manila
,◉ novaliches plant. Answer: plant supplying west zone of mm
◉ balara. Answer: plant supplying the east zone of mm
◉ indirect pressure distribution. Answer: classification of public
water distribution using deep wells
◉ direct pressure distribution. Answer: public water distribution
where water undergoes the filtration plant
◉ air pressure system. Answer: system of water dist which has less
initial cost but higher residual cost due to electricity consumption
◉ 10. Answer: maximum floor able to reach pneumatic tank
◉ 7.5. Answer: how many gallons per 1 f.u.
◉ 50-100. Answer: probability of simultaneous use for 1-5 FU
◉ 25-50. Answer: probability of use for 6-50 fixture units
◉ 10-25. Answer: probability of simul. use for 50+ f.u.
,◉ Air break. Answer: A piping arrangement in which a drain from a
fixture appliance or divice discharges into a receptor at a point
below the flood level rim and above the trap seal
◉ Air chamber. Answer: Now called water hammer arrestor
◉ Air gap drainage. Answer: Unabstructed vertical distance between
the outlet of the waste pipe and the flood level rim of the recptor it is
discharging "air gaps are required where backflow can occur due to
back siphonage"
◉ Air gap water distribution/ effective opening. Answer: Vertical
distance between the lowest opening,pipe, faucet supplying water to
a tank fixture or other device and the flood level rim of the receptor.
diameter of the fixture discharge is the effective opening.
◉ Battery fixtures. Answer: Any group of two or more similar
adjacent fixtures that discharge into a common horozontal waste or
soil branch. Can be battery vented in up to groups of 8 fuxtures
◉ Clinical sink. Answer: A sink primarily for waste very similar to
the characteristics of a toilet
, ◉ Combination fixture. Answer: Kitchen sink or laundry tub that has
one trap for 2 compartments tied in within 30 inches of the trap
◉ Conductor/ rain leader. Answer: Vertical drain pipe within the
building that convays storm water from the roof to its connection to
the building storm drain or other point of disposal
Rain leader is the same but on the exterior of the building.
◉ Critical level. Answer: The bottom of the back flow preventer
unless stamped on the back flow prevention device by the
manufacturer that determines the minimum elevation above flood
level rim.
◉ Load factor. Answer: The percentage of the total connected fixture
unit flow which is likely to occur at any point in the drainage system
◉ Local ventilating pipe. Answer: A pipe on the fixture side of the
trap which vapor or foul air is removed from the fixture
◉ Reduced pressure zone backflow preventer assembly. Answer:
Provides the highest level of protection against back pressure
backflow.
