Water Supply Systems
Section Contents Exposed Piping Underground
Piping
5
Exposed Piping

• Example Shown
• Pipe Runs In Tunnels

6
Exposed Piping

• Example Shown
• Pipe Runs On Ceiling

7
Underground Piping

• Water supply lines may be located underground or
  in tunnels.
• Underground pipe leaks require special repair
  procedures.
• Contact your supervisor if you suspect an
  underground leak.

Waste Water Systems
Section Contents Chemical Waste System Acid
Dilution Basins Grease Interceptors Traps
9
Chemical Wastes
Glass piping is used for acids in Middle School
High School chemistry laboratories.
10
Acid Dilution Basins

• Dangerous!!
• May Contain
• Hazardous Wastes
• Use A Contract Cleaning Service

11
Grease Interceptors

• Waste water is held briefly in the box so fats,
  oils, and greases may separate (float) from the
  wastewater.
• Baffles hold the greases in the box, but allow
  wastewater to flow out the discharge pipe.

12
Grease Interceptors
Grease interceptors are cleaned annually, or as
needed, by means of vacuuming.
13
Traps

• Example Shown
• Sink With Exposed Trap

14
Floor Drain Traps

• Trap should contain water.
• Add water if it is dry to eliminate odors.
• Hidden Trap
• Clean Out

15
Hidden Traps

• Example Shown
• Hidden Trap For
• Sanitary Waste

16
Storm/Clear Water Traps
Example Shown

• A condensate line from a chiller.
• Note the open drop which prevents back-up

17
Water Traps
Example Shown

• Clear condensate line (plastic tubing) discharges
  to a floor drain with a hidden trap.

18
Trap Trouble Shooting
Prior to writing a work order

• Take trap apart
• Remove foreign objects
• Clean trap

19
Normal Trap Cleaning Methods

• Use plunger
• Use closet auger
• Remove trap

20
Valves
Section Contents Gate Valves Ball
Valves Automatic Valves Battery Operated
Valves AC Powered Valves Motorized Flush
Valves Check Valves Back Flow Prevention Valves
21
Gate Valves

• Older installations
• Current installations
• are 4 inch diameter
• or larger

22
Ball Valves
When the handle is in line with the pipe, the
ball valve is open.

• Fresh water systems
• Smaller installations
• Newer installations

23
Ball Valves

• Four (4) ball valves are open.
• They may be shut-off to repair or replace the
  pumps.

24
Battery Operated Valves

• New Installations
• Example Motion Detecting
• Self-Flushing Toilets

25
AC Powered Valves

• AC current is required to open this valve.
• Used in dishwashers

26
Motorized Flush Valves
These valves are to be repaired by District
Plumbers only!
27
Check Valves

• Prevents back flow
• Used for domestic
• water

28
Check Valves

• Used in sump pump pits
• Prevents back-flow
• Check Valve

29
Backflow Prevention Valves

• Protect potable water
• Required on outside hose bibs
• Required on boiler water systems to prevent back
  up of chemicals into potable water
• Annual checks are required by law.

30
Backflow Prevention Valves
Prevents cleaning materials from backing up
into, and contaminating, potable water

• Example Shown
• Infrared Sensors

38
Metered Faucets

• Metered faucets deliver a set amount of water
  when the valve handle is pushed down.
• After the metered amount of water has been
  delivered, the valve will shut off automatically.

39
Standard Metered Faucets
Many faucet types have been installed. The
standard faucet is the Chicago Faucet

• Minimize repair costs
• Maximize durability
• Access to service parts
• Replacement program

40
Water and Repair Costs

• Metered faucets save 1/3 of the water use costs
  because they turn off automatically.
• Older faucets cost 3 times more to operate that
  metered faucets.

41
Faucet Trouble Shooting
If you have low water pressure or no water

• Check the supply valves. Are they on or off?
• Remove and clean the aerator.

42
Drain Pipe Leaks
When a leak is noticed from an exposed drain
pipe, tighten the connections using a wrench.
43
Drain Cleaning

• Remove grates
• Clean traps
• Remove all foreign objects
• NO DRAIN CLEANERS!

• Corrosive to pipes
• Dangerous and can cause chemical burns.
• Potential negative reaction with other wastes or
  objects that may be present in the drain.

44
Urinals and Toilets
Section Contents Urinals Toilets
45
Floor Mounted Urinals

48
Signs of Urinal Trouble
Ask the following questions at the first sign of
trouble

• Has there been a recent water meter change?
• Is water pressure low throughout the building?
• If so, call Russ Moeller, Master Plumber.

49
Urinal Cleaning

• Cleaning Procedure
• Use rubber gloves
• Remove urinal strainer
• Clean the grate!!!
• No caustic cleaners
• Do Not Use urinal blocks

50
Urinal Care

• Floor drains should be nearby for overflow or
  clean-up.
• If you notice drain odor (sewer gas), add water
  to the floor drain trap. If the bend in the trap
  is filled with water, sewer gas cannot escape
  into the bathroom.
