If you live in a town or city, you probably don't give much thought to how the water you use each day gets to your house.

Move a few miles out of town and the picture can change. Your water supply is independent from the neighbor's down the road. Each home has its own well and electromechanical system for getting the water from the well to the house. At the heart of each system is a pump. The most common types are jet pumps and submersible pumps.

How Water Pumps Work

No matter what kind of system you have, the components on the output side of all pumps are similar.

Pumps are not intended to run continuously, and they don't start each time you open a tap or flush the toilet. In order to provide consistent water pressure at the fixtures, the pump first moves water to a storage tank. Inside a modern tank is an air bladder that becomes compressed as the water is pumped in. The pressure in the tank is what moves the water through the household plumbing system.

When the pressure reaches a preset level, which can be anywhere from 40 to 60 psi, a switch stops the pump. As water is used in the home, pressure begins to decrease until, after a drop of about 20 psi, the switch turns on the pump and the cycle is repeated. You'll find the pressure gauge mounted on the tank with wires leading to the switch that controls the pump.

Pump Types

4" Submersible Well Pumps

Franklin Electric offers a broad selection of submersible well pumps. 4" pumps are used for residential and light commercial. They range in horsepower from ½ to 5 HP, with the most popular size range ½ to 1-1/2 HP. Capacity ratings are 5, 7, 10, 15 and 22 gallons per minute with heads as high as 990 feet.

Jet Pumps

Myers HJ Series is one of the most popular pump series in the market today. The HJ Series is known for its superior performance and dependability in home, farm, business and industrial applications around the world.

Sump Pumps

Sump pumps are designed to keep water out from where it doesn't belong. They come in many styles and sizes for all different kinds of applications. Submersible is the most popular style although pedestal pumps are also available.

Waste/Utility Water Pumps

Sani-flo Systems - The Saniswift is a drain pump that is suitable for use in a basement apartment or anywhere in the house where additional fixtures are most wanted. It will pump the waste water away from a variety of sources such as: a kitchen sink, laundry sink, washing machine (indirect connection), dishwasher, bar sink, etc.

The Saniswift's modern style prevails over other bulky relics. This system offers powerful and economical pumping action in a compact, contemporary design. With unprecedented performance and features, this pump is unmatched in its class.

Pre-Charged Pressure Tanks

Well-X-Trol Tanks by Amtrol

Amtrol Inc. invented the first pre-pressurized well tank over 50 years ago. This revolutionary product featured an innovative design using a hoop ring and groove to lock the diaphragm, liner and shell together in a totally unique way.

This tradition of innovation continued with Amtrol's Next Generation Well-X-Trol, which utilized high strength steel to deliver 150 psig working pressure - 20% higher than competitve well tanks. Backed by an industry leading 7 year warranty.

Flex Lite Fiberglass Tank

The Flex-Lite FL series' improved CAD2 diaphragm design is stronger and won't crease and wear out like bag designs. Flex-Lite well tanks features a chlorine resistant 100% butyl diaphragm with a precision molded copolymer polypropylene lower water chamber for superior air and water separation. This patented design allows each size tank to have a properly sized water chamber, matched to the drawdown performance of that tank. When it comes to performance and durability, the CAD2 system cannot be beat.

How Water Heaters Work

Whenever someone turns on a hot water faucet, heated water is drawn from the top of the tank and is replaced by cold water that is carried to the bottom through the dip tube. When the water temperature drops, a thermostat activates the heat source (a burner in a gas model -- two heating elements is an electric.)

A gas heater has a flue running up the center and out the top to vent deadly gasses. An electric heater needs no venting. In both, an anti-corrosion anode attracts corrosion that would otherwise attack the tank's walls.

Inside a Water Heater

If you were to cut a water heater in half, you would find that it looks something like this (electric on the left, gas on the right):

A gas water heater is nearly identical to an electric water heater, except that it does not contain the two heating elements, but instead has a gas burner at the bottom, with the chimney running up through the middle of the tank.

A water heater consists of the following parts, as shown in the figure:

    A heavy inner steel tank that holds the hot water

    Typically, this tank holds 40 to 60 gallons. It has to be able to hold the pressure of a residential water system, which typically runs at 50 to 100 pounds per square inch (psi). The tank is tested to handle 300 psi. The steel tank normally has a bonded glass liner to keep rust out of the water.

    Insulation surrounding the tank

    A dip tube to let cold water into the tank

    A pipe to let hot water out of the tank

    A thermostat to control the temperature of the water inside the tank (Many electric water heaters have a separate thermostat on each element.)

    Heating elements to heat the water (These are the thick electric elements similar to those you see inside an electric oven.)

    A drain valve that allows you to drain the tank to replace the elements or move the tank

    A pressure relief valve (This is an important safety feature that keeps the tank from exploding.)

    A sacrificial anode rod to help keep the steel tank from corroding

How to Choose a Water Heater

Heating water accounts for approximately 15 percent of a home’s energy use. High efficiency water heaters use 10 to 50 percent less energy than standard models, saving homeowners money on their utility bills. Actual energy savings from high efficiency water heaters depend on family size, heater location, and the size and placement of water pipes.

Water Softeners

A water softener can dramatically extend the life of everything that your water flows through or goes to. Hard water from a well or municipal source clogs pipes with scale and reduces water pressure and over time the life of appliances, fixtures and surfaces.

The body, hair, towels, clothing and dishes rinse cleaner with the improvement of a water conditioning and filtration system used to remove these unwanted substances. Using less detergent and soap helps keep it green, you lose less water from rinsing and re cleaning surfaces.

Reverse Osmosis Systems

A Reverse Osmosis System treats your water through three different filters. Eliminating costly and burdensome bottled water, and it stays hidden under your sink.

Exclusive manifold plate with patented channel design reduces tubing connections and simplifies installation. Automatic shut-off signals the system to stop making water until more is needed. You will have delicious, sparkling clear water and ice cubes, pristine, flavorful beverages and soups. Prolong the life of your humidifier, iron, fish tank and equipment. Dishes rinse cleaner with no spotting, great for pets too. Environmentally sound with no chemicals.

UV Systems

A simple but practical method of destroying disease causing microorganisms in water are Ultraviolet systems that destroy many forms of harmful bacteria, E. Coli, Protozoan cysts, and water-borne diseases found in water. Unlike traditional disinfection methods such as chlorination UV imparts no residual chemicals into the water. This compact line of ultraviolet disinfection systems is ideally suited for point of use filtration, RO pre or with a myriad of other applications requiring the flexibility this design offers. Low power consumption operates for pennies a day. These systems are designed for easy homeowner maintenance. The UV lamp can be changed without interrupting the water flow.

Having your water treated is not only smart but can save you money and potentially your health! According to the Centers for Disease Control and Prevention in Atlanta, Georgia, between 900 and 1,000 people die and another million become sick annually from microbiological illnesses linked to contaminated drinking water.
