Introduction - Brac RESIDENTIAL Series Installation Manual And User's Manual

III. Introduction
Congratulations on the purchase of your new BRAC SYSTEM. The BRAC SYSTEM can
help you save over 30% on your indoor water consumption, which will help to sustain our
most precious resource and provide for a better future for the generations to come.
When integrated into the plumbing of your home, the BRAC SYSTEM captures the water
used in your shower, bathtub and clothes washing machine, and recycles it to fl ush your
toilets.
(See fi gure 1)
The greywater from your shower, bath and laundry enters the BRAC SYSTEM through
the greywater inlet pipe where it passes through a 100-micron pleated cartridge fi lter and
collects in the lower portion of the BRAC SYSTEM tank. A 2" overfl ow pipe connected to
your sewer line prevents the tank from overfi lling.
A potable water inlet pipe, controlled by an ultra-sonic level sensor and solenoid valve,
assures a minimum level of water in the tank, preventing the pump from running dry and
making sure there is always water to fl ush your toilets.
The collected water is drawn through a foot valve by a pump which provides greywater at
pressure to the greywater outlet and the irrigation/ priming faucet, supplying greywater to
your toilets and, if allowed, your garden.
An electronic chlorination system circulates the greywater through a separate chlorinator
at programmable intervals, allowing the greywater to be treated to a safe level without
becoming over-chlorinated. A built-in vacation mode assures that the greywater is not over-
chlorinated. The fi lter is easily accessed for cleaning, and a clean-out valve is provided for
fl ushing the tank.
Only a licensed plumber should install the BRAC SYSTEM. We recommend that your
plumber also install a fresh water bypass and shutoff valve to provide backup clean water
to your toilets in the event of a power failure, or should your system require removal for
servicing. We also recommend a greywater bypass to overfl ow be installed (Figure 1), so
that in the event of a fi lter obstruction, your bath and shower drains will not back up.
LAUNDRY OPTION: While laundry water is suitable for reuse, the presence of lint may
increase the frequency of fi lter cleanings required. If using laundry water as a grey water
source, Brac SystemsBRAC SYSTEMS INC. offers a pre-fi lter that will increase the duty
cycle of the primary fi lter. Contact your local dealer for more information. Research and
testing has shown that in the average household, with each member taking an average of
one shower per day, suffi cient quantities of greywater are generated by bathing alone to
match the amount of average fl ushes per day in the same household. So you may choose
to omit capturing the laundry water when installing your system. You may also consider
installing both a traditional drain alongside a greywater drain to the BRAC SYSTEM behind
your washing machine. This will allow you to include or exclude your laundry water from
greywater collection simply by moving the hooked drain hose behind your washer from one
hole to the other. Just be sure to refasten the hose securely.
