Water and Sanitary Systems Flashcards
Supply systems
Supply clean, clear, potable water in sealed systems under pressure
Sanitary waste systems
Remove contaminated water
Storm drains
Similar to sanitary systems with larger pipes
Supply water
Clean, clear, potable, suitable for drinking
Acidity
Rain is clear of any mineral content but is slightly acidic
pH
(greater acidity = lower pH)
Very acidic pH
< 5
Slightly acidic pH
6.0 - 6.9
Basic or alkaline solution pH
> 7
Hardness
Groundwater that has absorbed minerals such as limestone, calcium, and magnesium
Pneumatic Tank System
Pressurized tank in basement to serve upper level
Downfeed System
Roof-mounted tank supplies water to upper building floors
Carcinogens
Typically, man-made substances found in groundwater and wells
Tankless System
Requires one or more variable speed pumps to provide required pressure
Friction
Flow rate is affected by pressure losses due to friction
Soil lines
Water from toilets, urinals, etc. (black water)
waste lines
All other waste water from
sinks, etc. (gray water)
Vent stack
Small, air intake for all fixtures, open to outside
Sanitary system vent
relieves built-up
pressure and breaks siphoning action
(suction
Soil stack
Large pipe into which all soil and waste lines empty, open to outside
Stack vent
Section above highest fixture, vents soil stack
Cast iron
Sanitary lines inside building
Ceramic
Sanitary lines outside building
