WATER USAGE
WATER CONSERVATION = ENERGY CONSERVATION
+ LESS FILTER MAINTENANCE
TOILETS: A 1.6-gallon flush toilet may reduce total domestic water consumption by 50%
compared with typical 4-5 gallon toilets. They are now standard in U.S.A.
IRRIGATION SYSTEMS: Many drip, trickle or flood irrigation systems will function on LOW
PRESSURE. It is wasteful of energy to supply pressurized water where it is not required. You
may wish to arrange separate gravity flow from your water source or storage tank, if possible.
Or, if a small amount of lift/pressure is required, consider a low-pressure DC pump such as a
marine bilge or circulator pump.
LOW FLOW SHOWER HEADS are recommended IF you are running 30-50 PSI pressure
range. At lower pressures, they may not provide adequate flow.
FREEZE PROTECTION
If freezing of your outlet pipe is to be expected, you may avoid the frequent necessity of
replacing fuses or resetting your breaker by installing an ADJUSTABLE PRESSURE RELIEF
VALVE at the pump outlet. This will allow water to flow back into the well when outlet pipe is
blocked. Order the valve from your dealer or any electric or plumbing supplier (Grainger's part
number 1X624 or equivalent, about $15). To adjust, be sure water has reached the highest
point in your system. Loosen the valve til it leaks water, then tighten it gradually JUST PAST
the point where it stops. Be sure water will not drip onto the motor/pump.
To PREVENT freezing of exposed pipes (Slowpump system) you might consider the primitive
method of drilling a small "weep hole" in the outlet pipe, below ground level. The pipe will drain
when pumping stops but a small amount of water will be wasted during pumping. Set the outlet
pipe to spill into the top of the tank so that the tank will not drain, or install a check valve and
"vacuum breaker" to allow pipe to drain.
Water WILL drain back through the pump if allowed to, but it will do so slowly. If this is desired,
do not use any check valves or foot valve. Pump must have suction draw of no more than a few
feet, however. If pump drainage is required, position pump vertically (head downward) or
horizontally with intake and outlet facing downward (see "Changing Pump Head Position", p.5).
Take every precaution to PREVENT pump freezing. The forged brass pump head will survive
most light freezes, but a hard freeze may damage it. If you insulate your pump for freeze
protection, keep the motor exposed so it won’t overheat.
