Water Bladder Tank Basics
1. Water bladder tanks are tanks which contain a rubber bladder that is filled with either water or air. The majority of water bladder tanks have water-filled bladders. When a water faucet is turned on or a toilet is flushed, the water is piped in from the water tank. As the water pressure and air pressure get low, the contacts on the pressure switch click together. The pressure switch sends an electrical current to the water pump which causes the water pump to kick on and pipe water back into the water bladder tank. The amount of time it takes for the pressure switch to click on depends upon the size of the water bladder tank. The larger the water bladder tank, the longer it will be before the pressure switch starts to deliver electrical current to the water pump.
How the Water Bladder Tank Works
2. Water leaves the water bladder tank each time that the water is used in your home or yard. As the water leaves the tank, the bladder gets smaller and the water pressure drops within the tank. Water bladder tanks also contain air within the water tank. When the water leaves the tank, the air pressure inside the water bladder tank also drops. A pressure control switch, which is usually located near the water tank, senses the drop in pressure within the tank and, after the pressure lowers to a certain level, the contacts within the pressure switch are pushed together, which turns on the water pump. The activated water pump draws water from the well which refills the tank and restores the water and air pressure within the tank.
How the Water Bladder Tank Gets Refilled
3. While the pressure switch is activated, the water pump, which is generally located near the tank or inside the well itself, pulls water from under the ground and pumps the water back into the water tank's bladder. As the bladder is filled, the water pressure and air pressure rise back to their normal levels. After the water pressure and air pressure are back to normal, the contacts within the pressure switch are pulled away from each other. Once the pressure switch stops supplying power to the pump, the water pump stops pumping water into the tank. This process begins again each time water is used within the home or in the yard.

Beryllium copper
Beryllium copper also known as copper beryllium, BeCu or beryllium bronze, is a metal alloy of copper and 0.5 to 3% beryllium, and sometimes with other alloying elements. Beryllium Copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining qualities. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace. Beryllium-containing alloys create an inhalation hazard during manufacturing due to their toxic properties.
Beryllium copper is a ductile, weldable, and machinable alloy. It is resistant to non-oxidizing acids (for example, hydrochloric acid, or carbonic acid), to plastic decomposition products, to abrasive wear and to galling. Furthermore, it can be heat-treated to improve its strength, durability, and electrical conductivity. Beryllium copper attains the highest strength (to 1,400 MPa (200,000 psi)) of any copper-based alloy.[1]
As beryllium compounds are toxic there are some safety concerns for handling its alloys. In solid form and as finished parts, beryllium copper presents no particular health hazard. However, breathing its dust, as formed when machining or welding may cause serious lung damage.[2] Beryllium compounds are known human carcinogens when inhaled.[3] As a result, beryllium copper is sometimes replaced by safer copper alloys such as Cu-Ni-Sn bronze
Beryllium copper is a non-ferrous alloy used in springs, spring wire, load cells and other parts that must retain their shapes during periods in which they are subjected to repeated stress and strain. Due to its electrical conductivity, it is used in low-current contacts for batteries and electrical connectors. Because Beryllium copper is non-sparking but physically tough and nonmagnetic, it is used to make tools that can safely be used in environments where there are explosive vapors and gases e.g. oil rigs. Beryllium copper fulfills the demands of ATEX directive for use in Zone 0, 1, and 2.[5] Various tool types are available e.g. screwdrivers, pliers, spanners, cold chisels and hammers. Another metal sometimes used for non-sparking tools is aluminum bronze. Compared to tools made of steel, beryllium copper tools are more expensive, not as strong and wear out more quickly. However, the advantages of using beryllium copper in hazardous environments outweigh these disadvantages.

Ecotrap®
Ecotrap®
ecotrap-diagram.gifOur patented EcoTrap® relies on the proven and simple vertical trap principle.
1. Urine flows down into the EcoTrap® drain insert.
2. In the EcoTrap® the urine passes through a floating layer of BlueSeal® liquid, which forms a barrier that prevents sewer vapors from escaping to the restroom atmosphere.
3. Urine under the barrier layer overflows into the central tube and runs down to the conventional drain line.
4. The layer of approx. 3 ounces of BlueSeal® will last for about 1500 sanitary uses. The liquid is then simply replenished. Task time: 20 seconds. Trap does not need to be touched.
5. The EcoTrap® retains urine sediments and is easily replaced 2-4 times a year according to traffic to the fixture. A special tool, the X-Traptor®, is used to remove the EcoTrap®. This deters vandalism. Task time: 3-4 minutes.
Please see our simple maintenance instructions here.
6. Drain lines are free of hard encrustations. They are easily accessed by removing the EcoTrap® with the special X-Traptor® tool.
The patented vertical EcoTrap® design provides superior efficiencies to other, more complicated trap arrangements. It does not need to be cleaned out as it is simply changed out. It also helps retain urine sediments. Urinals without trap inserts may clog the urinal’s internal trapway.

Silicone grease
Silicone grease is a waterproof grease made by combining a silicone oil with a thickener. Most commonly, the silicone oil is polydimethylsiloxane and the thickener is amorphous fumed silica. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent on the type and proportion of the components.
Silicone grease is commonly used for lubricating and preserving rubber parts, such as O-rings. Additionally, silicone grease does not swell or soften the rubber, which can be a problem with hydrocarbon based greases. It functions well as a corrosion-inhibitor and lubricant for purposes that require a thicker lubricant, such as the operating mechanism of the M1 Garand rifle.
Thermal grease often consists of a silicone grease base, along with added thermally conductive fillers. It is used for heat transfer abilities, rather than friction reduction.
Silicone grease is also used widely by the plumbing industry in faucets and seals, as well as dental equipment. Electrical utilities use silicone grease to lube separable elbows on lines which must endure high temperatures. Silicone greases generally have a temperature range of -40 to 400 °C.
