Q

Types of well pump:

Uses a Venturi effect and a waterjet sent from the surface to impel water to rise

A

Ejector

21
Q

Types of well pump:

Can be used for Wells under 25 feet

A

Suction pumps

22
Q

Types of well pump:

For deep wells with high-capacity

A

Turbine pumps

23
Q

Types of well pump:

For small residential, a pump below the waterline pumps water to a pressure tank

A

Subversive pumps

24
Q

Newman municipal water systems typically pump through water mains with pressure of

A

50 psi

25
Q

This party is responsible to extend lines from property to the Watermain if not adjacent to the property line

A

Property owner

26
Q

These are installed at the edge of the property and inside the building at the service entrance

A

Service controls, or valves

27
Q

Used to protect the potable water supply from contaminated water by stopping return water from the building from flowing back into the public water supply

A

Reduce pressure backflow preventer

28
Q

Water supply system that uses a pressurized tank that’s to be in the basement to supply water under pressure to floors above

A

Hydropneumatic system

29
Q

Pressure from the Watermain is used to pump directly to the fixtures

A

Upfeed system

Upfield systems Limited to 40-60 feet building height

30
Q

Primary disadvantage of a down feed system

A

Added structure to support weight of system on roof

31
Q

In a downfeed system pressure regulator valves are required after about this height

A

138 feet

32
Q

Pressurized tank in the basement supplies water to higher levels using compressed air to push water up

A

Pneumatic tank

33
Q

Multiple variables speed pumps provide water pressure at whatever demand rate the building requires

A

Tankless

Doesn’t take up space, but pumps can I have a short lifecycle

34
Q

Waterflow that occurs when soil is infiltrated to full capacity

A

Surface runoff

35
Q

Process in which water on the ground surface enters the soil

A

Water infiltration

36
Q

The reservoir which debris in sediment from run off my settle before it enters the storm drain

A

Catch basin

37
Q

Drain or channel that permits the passage of water below ground. Typically a large diameter concrete or metal pipe often used under a road

A

Culvert

38
Q

Underground conduit used to carry rainwater from a catch basin to a body of water

A

Storm drain

39
Q

Underground structure, above the water table, the disposes of unwanted water by dissipating it into the ground

A

Drywell

40
Q

Perforated pipe surrounded by granular fill used to release hydrostatic pressure from foundation or retaining walls

A

Drain tile

41
Q

Order from toilets, including human waste

A

Blackwater

42
Q

Catch grease, hair, oil rags, money, etc. that gets into a plumbing system

A

Interceptor

43
Q

Keeps methane gas from entering a building well also catching Greece and small jewelry before going down the sanitary system

A

Trap

44
Q

Safety feature, faucets are mounted 2 inches minimum above the highest possible level of waste water to prevent any contaminated water being safe and back in

A

Air gaps

45
Q

A pump used in hot water systems for maintaining for circulation of water or other liquid

A

Circulator

46
Q

A piece of metal placed in the water tank to attract mineral deposits so they don’t form on tank or equipment

A

Anode

47
Q

Three strategies for storm water quality control

A

Infiltrate run off into the soil.
Retain/detain run off for a later release.
Convey run off slowly through vegetation.

48
Q

Single supply pipe water heater

A

Minimizes piping cost.

Can result in longer wait times for water.

49
Q

Two pipe circulating system hot water:

A

All fixtures connected with supply and return.
Water slowly circulates through natural convection.
Hot water rises to highest fixtures and falls after cooling.

50
Q

When sizing hot water systems for commercial and institutional buildings it’s important to consider the trade-off between

A

Recovery time and storage capacity

51
Q

Hot water heater size is based on two factors:

A

Total daily use

And peak-hour demand
