"Always in hot water!"
SAVE WATER! At ONLY $179.95, the eco friendly Hot Water Lobster Instant Hot Water Valve provides
faster hot water which
saves water, saves energy and saves time.  How long does it take for hot water
to get to your faucet or shower?  A lot of precious water is wasted down the drain while waiting for hot
water.  Even worse is the cost to heat the cold replacement water, which enters your house at the cold
ground temperature.

HOW IT WORKS! When the water in your hot water pipe and the Hot Water Lobster control valve cools
below the user adjustable temperature (77-140 F. degrees), the thermal materials within the
Water Lobster
control valve contract and silently open the valve.  Thermal convection within your hot
water tank (differential of pressure between the top of the tank and the bottom of the tank) naturally
circulates the cooled water through your existing cold water pipes and back to    the hot water tank for
reheating.  Your existing hot water tank now uses less energy reheating the warm water instead of
cold ground temperature water.  When fresh hot water enters your hot water pipe and reaches the
Water Lobster
control valve, the valve automatically closes.  This maintains hot water at the control
valve without wasting water or wasting energy.  Turn on your faucet or shower; and you get instant hot
water instead of wasting it down the drain!  Installing the
Hot Water Lobster instant hot water control
valve at the fixture furthest from your hot water tank (as shown in the installation diagram) will provide
faster hot water to all of the fixtures in your house.

NO ELECTRICITY NECESSARY! The Hot Water Lobster is all mechanical and designed to provide an
electricity free solution to maintain hot water at the tap.  This makes installation a snap (less than 10
minutes).  Other hot water solutions require the use of electricity and pumps that make installation
difficult and the pumps are often noisy and wear out in 2-4 years.

MORE HOT WATER! Adds as much as 10% more capacity to your current hot water system (by
keeping the water in your hot water pipes hot!).

KEEP PIPES FROM FREEZING!     The Hot Water Lobster instant hot water valve automatically allows
water in your pipes to circulate when the control valve cools below the set temperature (even when
your electricity goes out).

REDUCES CONDENSATION! The Hot Water Lobster instant hot water valve reduces condensation on
pipes and toilets basins.

MAINTENANCE FREE! The Hot Water Lobster has a solid brass valve body with an adjustable thermal
controlled stainless steel valve stem enclosed in a mounting box.

EASY INSTALLATION! The Hot Water Lobster comes complete with the mounting box, 4 sets  of 12"
flexible water lines and standard brass fitting.  All pre-assembled and tested for an easy 10-minute

STATISTICS! *A typical family wastes approximately 12,000-17,000 gallons of water annually waiting
for warm water to reach the tap.                 
*as determined by GAMA (Gas Appliance Manufactures Association)

Note: Circulation of water by thermal convection must not be restricted (no check-valves) between the
water heater tank  and the Hot Water Lobster Instant Hot Water Valve.

Water conservation has become an essential practice in all regions, even in areas
where water seems abundant.

In addition to saving money on your utility bills, water conservation helps prevent water
pollution in nearby lakes, rivers and local watersheds. Conserving water can also
extend the life of your septic system by reducing soil saturation, and reducing any
pollution due to leaks. Overloading municipal sewer systems can also cause untreated
sewage to flow to lakes and rivers. The smaller the amount of water flowing through
these systems, the lower the likelihood of pollution. In some communities, costly
sewage system expansion has been avoided by communitywide household water

1. Install a temperature controlled hot water recirculation valve to your plumbing, which
provides faster hot water (so water is not wasted down the drain waiting for water to run
hot at your faucet or shower). This simple eco-friendly, DIY installation (no water pump
required) can save water (an average household up to 17,000 gallons per year). The
eco-friendly Hot Water Lobster Instant Hot Water Valve also saves energy costs and
can prevent pipe freezing.

2. Don't use the toilet as an ashtray or wastebasket. Every time you flush a cigarette
butt, facial tissue or other small bit of trash, five to seven gallons of water is wasted.

3. Check your toilets for leaks. Put a little food coloring in your toilet tank. If, without
flushing, the color begins to appear in the bowl within 30 minutes, you have a leak that
should be repaired immediately. Most replacement parts are inexpensive and easy to

4. Use your water meter to check for hidden water leaks. Read the house water meter
before and after a two-hour period when no water is being used. If the meter does not
read exactly the same, there is a leak.

5. Install water-saving shower heads and low-flow faucet aerators. Inexpensive water-
saving low-flow shower heads or restrictors are easy for the homeowner to install. Also,
long, hot showers can use five to ten gallons every unneeded minute. Limit your
showers to the time it takes to soap up, wash down and rinse off. "Low-flow" means it
uses less than 2.5 gallons per minute.

Also, all household faucets should be fit with aerators. This single best home water
conservation method is also the cheapest!

6. Put plastic bottles or float booster in your toilet tank. To cut down on water waste,
put an inch or two of sand or pebbles inside each of two plastic bottles to weigh them
down. Fill the bottles with water, screw the lids on, and put them in your toilet tank,
safely away from the operating mechanisms. Or, buy an inexpensive tank bank or float
booster. This may save ten or more gallons of water per day.

Be sure at least 3 gallons of water remain in the tank so it will flush properly. If there is
not enough water to get a proper flush, users will hold the lever down too long or do
multiple flushes to get rid of waste. Two flushes at 1.4 gallons is worse than a single 2.0
gallon flush. A better suggestion would be to buy an adjustable toilet flapper that allow
for adjustment of their per flush use.  Then the user can adjust the flush rate to the
minimum per flush setting that achieves a single good flush each time.

For new installations, consider buying "low flush" toilets, which use 1 to 2 gallons per
flush instead of the usual 3 to 5 gallons. Replacing an 18 liter per flush toilet with an
ultra-low volume (ULV) 6 liter flush model represents a 70% savings in water flushed
and will cut indoor water use by about 30%.

7. Insulate your water pipes. It's easy and inexpensive to insulate your water pipes with
pre-slit foam pipe insulation. You'll get hot water faster plus avoid wasting water while it
heats up.

8. Take shorter showers. One way to cut down on water use is to turn off the shower
after soaping up, then turn it back on to rinse. A four-minute shower uses
approximately 20 to 40 gallons of water.

9. Turn off the water after you wet your toothbrush. There is no need to keep the water
running while brushing your teeth. Just wet your brush and fill a glass for mouth rinsing.

10. Rinse your razor in the sink. Fill the sink with a few inches of warm water. This will
rinse your razor just as well as running water, with far less waste of water.

11. Use your dishwasher and clothes washer for only full loads. Automatic dishwashers
and clothes washers should be fully loaded for optimum water conservation. Most
makers of dishwashing soap recommend not pre-rinsing dishes which is a big water
savings. With clothes washers, avoid the permanent press cycle, which uses an added
20 liters (5 gallons) for the extra rinse. For partial loads, adjust water levels to match
the size of the load. Replace old clothes washers. New Energy Star rated washers use
35 - 50% less water and 50% less energy per load. If you're in the market for a new
clothes washer, consider buying a water-saving frontload washer.

12. Minimize use of kitchen sink garbage disposal units. In-sink garbage disposal units
require lots of water to operate properly, and also add considerably to the volume of
solids in a septic tank which can lead to maintenance problems. Start a compost pile as
an alternate method of disposing food waste.

13. When washing dishes by hand, don't leave the water running for rinsing
If your have a double-basin, fill one with soapy water and one with rinse water. If you
have a single-basin sink, gather washed dishes in a dish rack and rinse them with a
spray device or a pan full of hot water. Dual-swivel aerators are available to make this
easier. If using a dishwasher, there is usually no need to pre-rinse the dishes.

14. Don't let the faucet run while you clean vegetables. Just rinse them in a sink or pan
of clean water. Use a dual-setting aerator.

15. Keep a bottle of drinking water in the fridge. Running tap water to cool it off for
drinking water is wasteful. Store drinking water in the fridge in a safe drinking bottle.

16. Plant drought-resistant lawns, shrubs and plants. If you are planting a new lawn, or
over seeding an existing lawn, use drought-resistant grasses. Many beautiful shrubs
and plants thrive with far less watering than other species. Replace herbaceous
perennial borders with native plants. Native plants will use less water and be more
resistant to local plant diseases. Plant slopes with plants that will retain water and help
reduce runoff. Group plants according to their watering needs.

17. Put a layer of mulch around trees and plants. Mulch will slow evaporation of
moisture while discouraging weed growth. Adding 2 - 4 inches of organic material such
as compost or bark mulch will increase the ability of the soil to retain moisture. Press
the mulch down around the dripline of each plant to form a slight depression which will
prevent or minimize water runoff. For information about different mulch materials and
their best use, click here.

18. Don't water the gutter. Position your sprinklers so water lands on the lawn or
garden, not roads and paved areas. Also, avoid watering on windy days.

19. Water your lawn only when it needs it. A good way to see if your lawn needs
watering is to step on the grass. If it springs back up when you move, it doesn't need
water. If it stays flat, the lawn is ready for watering. Letting the grass grow taller (to 3")
will also promote water retention in the soil. Most lawns only need about 1" of water
each week. During dry spells, you can stop watering altogether and the lawn will go
brown and dormant. Once cooler weather arrives, the morning dew and rainfall will
bring the lawn back to its usual vigor. This may result in a brown summer lawn, but it
saves a lot of water.

20. Deep-soak your lawn. When watering the lawn, do it long enough for the moisture
to soak down to the roots where it will do the most good. A light sprinkling can
evaporate quickly and tends to encourage shallow root systems. Put an empty tuna
can on your lawn - when it's full, you've watered about the right amount. Visit our
natural lawn care page for more information.

21. Water during the early parts of the day; avoid watering when it's windy
Early morning is generally better than dusk since it helps prevent the growth of fungus.
Early watering, and late watering, also reduce water loss to evaporation. Watering early
in the day is also the best defence against slugs and other garden pests. Try not to
water when it's windy - wind can blow sprinklers off target and speed evaporation.

22. Add organic matter and use efficient watering systems for shrubs, flower beds and
lawns. Adding organic material to your soil will help increase its absorption and water
retention. Areas which are already planted can be 'top dressed' with compost or
organic matter.
You can greatly reduce the amount of water used for shrubs, beds and lawns by:
- the strategic placement of soaker hoses
- installing a rain barrel water catchment system
- installing a simple drip-irrigation system
Avoid over-watering plants and shrubs, as this can actually diminish plant health and
cause yellowing of the leaves. When hand watering, use a variable spray nozzle for
targeted watering.

23. Don't run the hose while washing your car. Clean the car using a pail of soapy
water. Use the hose only for rinsing - this simple practice can save as much as 150
gallons when washing a car. Use a spray nozzle when rinsing for more efficient use of

24. Use a broom, not a hose, to clean driveways and sidewalks

25. Check for leaks in pipes, hoses, faucets and couplings. A small drip from a worn
faucet washer can waste 20 gallons of water per day. Larger leaks can waste hundreds
of gallons. Leaks outside the house may not seem as bad since they're not as visible.
But they can be just as wasteful as leaks indoors. Check frequently to keep them drip-
free. Use hose washers at spigots and hose connections to eliminate leaks.

Water conservation comes naturally when everyone in the family is aware of its
importance, and parents take the time to teach children some of the simple water-
saving methods around the home, which can make a big difference.

                          How To Prevent Pipes From Freezing

If you've ever had the misfortune of having a water pipe freeze and burst, you know
first hand about what a devastating impact it can have on your home. The broken pipe
itself is actually relatively minor, but the damage caused by the leaking water running
through your walls and ceiling can mean a major reconstruction project, requiring
replacing drywall, ceilings and maybe even furniture and appliances. Here are some
ways to make sure you never have to go through that hassle.

1. Plan ahead and figure out which pipes could potentially freeze. Water pipes running
through unheated crawl spaces and pipes running through walls to the outside are
prime candidates for freezing.

2. Turn off the water supply lines running to your outside taps before the cold weather
arrives. There is usually a shut off valve in the water supply line close to where it goes
through the outside wall. Once the water is shut off inside, go outside and open the
outside taps as well. This will drain any water remaining in the pipe or in the tap, so
there's nothing to freeze.

3. Check any pipes that run close to outside walls. Put some insulation between the
pipe and the wall to help keep the cold away from the pipe.

4. Insulate any pipes that run through unheated crawl spaces. Wrap them with
finsulation and tape or put preformed pipe sleeve insulation along the pipes, then tape
the sleeves in place.

5. Install electrical heating tape (available at home stores) on any pipes that run
through areas that get really cold, like garages.

6. OR, simply an innovative and patented technology known as a “temperature
controlled hot water recirculating valve” (it’s a breeze to install-no pipe cutting,
soldering or electrical connections). It uses your existing water pipes and the thermal
convection generated by your water heater to keep water circulating back to your water
heater for reheating (not requiring a pump or any electricity). Warm circulating water
will not freeze. These systems are temperature-controlled and are easily adjustable to
meet your particular temperature needs. There is no water waste and it also reduces
the energy required to heat your water while it provides instant hot water to your
faucets and showers.
