Q

Pressure tank

A

Part of a well pump assembly
that reserves water for use. The tank
contains a bladder that puts pressure on the
water in the tank. When a faucet or spigot is
opened, the pressure forces the water
through the piping. Through gauges and
switches, the tank monitors the water
pressure and starts the pump when pressure
lowers to a predetermined level. When the
valve is closed, the pump continues until the
water has reached the upper pressure limit.

Q

Tankless water heater

A

A newer
style of water heater that does not
contain a holding tank. Water is
heated on demand after the unit
detects water flow. These units are
usually heated by natural gas
burners.

29
Q

Vent stack

A

Also called vent pipes.
These pipes permit equalization of
the pressure in the drain system
with the atmospheric pressure. This
prevents vacuum conditions that can
interfere with the natural flow of the
drain piping. The pressure on both
sides of drain traps is equalized,
assisting in proper flow.
