Low flow

Less water will now be needed while
you use the toilet. The US government has passed a law restricting
toilet flushes to a maximum of 1.6
gallons (about 7 .3Iitres} per flush.
Eljer Industries Inc has come up
with new models that depend on
gravity to flow away the wastes.
Using less water implies applying
extra pressure and this, in turn,
makes flushing a noisy business.
Eljer plans to introduce highly
advanced loos that use rim jets and a
0.2 horsepower electric motor.
Experts estimate that a family of
four can save about 19,000 gallons
(about 85,000 litres) yearly by using
these efficient low-flow models.
