What is a Well Pressure Tank?
For homeowners without city-regulated water services, a well is necessary in order to get running water in the house. A well pump, either submersible or a jet well pump, is used to deliver the water from the well to the plumbing fixtures inside your home. A well pump is connected to a well pressure tank, which acts as a reservoir to store the water that will be distributed throughout a home. As you might have guessed for the name, the well tank is pressurized with compressed air. This not only plays a role in the overall water pressure you get in your home, but also helps signal the pump when the water level gets too low and it’s time to refill. There are 3 different types of well pressure tanks depending on the type of mechanism they use to control the pressure. Air-Over-Water Pressure Tanks An air-over-water tank is usually made of galvanized metal with a fairly simple design. It’s often found in older homes and is not as popular today as other types of pressure tanks. As the name suggests, an air-over-water tank consists of a single chamber filled with water and pressurized air—nothing separates the two. The pressurized air pushes on the water, providing the necessary pressure for your home’s faucets. These tanks are generally larger than most modern models, yet have a capacity similar to much smaller tanks. This disparity in size and capacity of the tank may cause the well pump to cycle on and off more frequently, which may lead to premature pump burn-out. The single chamber design of these tanks also makes them prone to becoming water-logged due to air loss trough pin-hole corrosion. Diaphragm Pressure Tanks Diaphragm pressure tanks consist of two separate chambers: one for compressed air and another for water. A rubber diaphragm is permanently attached to the sides of the tank to separate water from air. It rises and falls with the water level. As water is pumped into the tank, the diaphragm is pushed up to the compressed air chamber which then triggers a sensor to shut off the pump. While efficient, these tanks can have problems with the diaphragm coming dislodged from the sides of the tank, causing water to flow into the compressed air chamber and preventing any pressure from building. If this happens, you will experience a drastic decrease in water pressure and your tank will need to be replaced. Some homeowners have also noted issues with the diaphragm folding over itself and causing false readings by the pump, burning out the pump and ruining the tank. Bladder Pressure Tanks Similar to diaphragm pressure tanks, bladder pressure tanks utilize two separate chambers for compressed air and water. The bladder is sort of a balloon filled with water that expands and contracts, triggering a sensor to activate the pump. Bladders, being self-contained entities, are useful for those worried about a diaphragm dislodging or folding under the pressure of compressed air. A bladder also generally lasts longer than a diaphragm, making your investment over time much more sensible. Things to Consider For Your Well Tank Getting an appropriately sized tank is essential to having constant water pressure throughout your entire home. A small tank will likely cause your pump to cycle on and off more frequently, which could result in premature wear or a need for total replacement. A tank that is too large for your home could cause the water to stagnate and develop an odd taste or other adverse effects.

Your well pump forces water to the surface. Without a pressure tank, the well pump would need to turn on every time you opened a faucet in order to maintain water pressure. Your well tank acts as a water storage container giving your well pump a much needed rest in between cycles. When air pressure inside the well tank decreases due to water usage, a pressure switch automatically activates telling the well pump to fill the tank. This assures an ample supply of well water will be on hand the next time you need it.
Troubleshooting guide If it appears that a bladder tank is not operating correctly, check the tank’s air charge:
Is it waterlogged? You should also check a bladder tank to determine if it’s waterlogged. A tank is waterlogged if it is completely filled with water or has too much water to function correctly. Waterlogged bladder pressure tanks contribute to the following problems:
Reasons for waterlogging Bladder tanks can become waterlogged for many reasons. Some of the more common reasons are:

Pump switches are designed to directly control a pump. Because they directly control a pump they have higher amp ratings so they can withstand startup and running current. The FLA (full load amps) of the pump runs through the switch. What is a control switch? Control switches monitor high or low level liquid conditions to activate control panels and alarms. They are narrow angle switches designed for a shorter range of travel and will engage or disengage with very little vertical movement. For example, a control switch used at the high level in a pump down application turns on when the float is slightly above horizontal and turns off when the float is slightly below horizontal. Control switches have smaller wire and are not designed to handle the direct amperage of a motor. They send a signal to an alarm or motor contactor, have a lower amp rating, and should never be wired directly to a pump. What does pump up mean? A pump up switch is used for filling in water and sewage applications. A pump up switch has normally closed contacts, meaning the contacts are closed when the float switch in hanging down. What does pump down mean? A pump down switch is used for emptying in water and sewage applications. A pump up switch has normally open contacts, meaning the contacts are open when the float switch is hanging down. What is normally open? If a pump switch is “normally open” the contacts are open when the float switch is hanging down. Normally open switches are used for pump down applications. What is normally closed? If a pump switch is “normally closed” the contacts are closed when the float switch is hanging down. Normally closed switches are used for pump up applications. What is a piggyback float switch? A piggyback float switch will plug into a power outlet. The back of it’s plug will have an outlet to plug in the pump. What is a vertical switch? Vertical float switches are used in applications with limited space. Float travels up and down on a fixed vertical rod. What is a diaphragm switch? A diaphragm switch is activated by pressure. They are often used in applications where a float may hang up. What is a tethered float switch? A tethered float switch is typically tethered to the pump or the discharge pipe. A tethered float is great for a larger basin and will allow for a longer pump run time. Do you sell mercury float switches? Yes, we currently sell mercury float switches. However, an increasing number of areas are restricting the sale of products containing mercury. We offer many mechanical alternatives for mercury switches.

Using a simple diaphragm and bladder, it is possible to have constant access to water without constantly running your pump.
HOW DOES A WATER WELL PRESSURE TANK WORK? First of all, using a pressure tank effectively means that you have to know how much water you are using. Based on the amount of water you use in a given time period, a professional can help you choose the size of tank that will suit your needs. From there, they will set a minimum and maximum pressure for your pump to activate. As you draw water out of your pressure tank, the pressure will drop. When it hits the minimum pressure threshold, the pump will activate and begin refilling the tank. Until then, you can still draw water from the tank without wasting any extra energy by running your pump. When the tank is sufficiently refilled, the pressure in the tank will rise to the maximum threshold and shut off the well pump automatically. WHAT DOES A WATER WELL PRESSURE TANK DO? Well, systems are typically inexpensive to maintain but pumps are difficult to repair or replace. The best way to reduce your costs is to minimize the amount of time that your pump spends running. By cycling your pump on and off it, you will get far longer life out of the components. Also, the cost of operating a pump in terms electricity can also be a huge factor. If your water well pump starts running every time you turn the water on, and always runs until the tank is filled to the brim, your power bill will skyrocket. By using a pressure tank, you can limit the amount of power used by only refilling the tank when it has reached the lowest threshold. Until then, there is no reason to regularly top the tank off. WATER WELL PRESSURE TANK MAINTENANCE Even with the help of pressure tank technology, it is possible to experience difficulties with your water supply. Most often this occurs when the rubber bladder which maintains pressure within the tank gets damaged or worn down. If the tank is not able to regulate its pressure accurately, the pump will begin turning on more frequently. This can cause a disruption in your water pressure, and you will likely see signs of the inefficiency when your power bill comes. Fortunately, a professional can service your pressure tank quickly and replace any worn parts to restore internal pressure to normal. Pressure tanks have made a big difference in the way well water systems operate. Today's well water systems are far more cost-effective and resource conscious. With less water and energy going to waste, you can appreciate savings each and every time you turn on the faucet.

Water bladder tanks are tanks which have a rubber bladder in them. The bladder is filled with water or filled with air as the case may be but as expected, a water bladder tank will definitely be filled with water. As soon as a toilet or sink knob is turned on, water is pumped from the water tank. When the water and air pressure gets low, the pressure switch’s contact locks. The pressure switch then conveys an electrical current to the water pump which will end up causing the water pump to start and pump water back into the water bladder tank. The length of time it will take for the pressure switch to lock on depends on the size of the water bladder tank. If the water bladder tank is large in size, it will definitely take time for the electrical current from the pressure switch to get to the water pump. Mechanism of Water Bladder Tanks When water is used in the home, or a compound generally, water is going to leave the water bladder tank. As water is being dispensed from the tank, the bladder will reduce in size and the water pressure within the tank will drop significantly. It is also important to point out that water bladder tanks contain air. As the water in the tank goes down, the air pressure will go down too. The pressure control switch, normally sited close to the tank, detects the drop in pressure within the tank. When the pressure drops to a certain level, the pressure switch’s contacts swiftly close together. This leads to the water pump getting switched on. The activated water pump then draws water from the well. At this point, the tank is refilled and water and air pressure within the tank is also restored back to normal. How does the Water Bladder Tank Get Refilled? As soon as the pressure switch is activated, the water pump which is normally found near the tank or inside the well immediately pulls water from below the ground back into the tank’s bladder. When the water bladder gets filled, water and air pressure goes back to normal levels. When the both of them have gone back to normal, the contacts on the pressure switch are pulled away from each other. With the relaxation of the pressure switch, water will immediately stop getting pumped into the tank. The whole process outlined above is what plays out as soon as water is used in the home. If you are looking to setup a bladder water tank in your home or factory do your best to ensure that it is purchased from a reputable shop and installed by them. A wrongly installed bladder tank will cost unnecessary money to replace and so it is very important to get it right the first time. It can’t be stressed enough how important it is to buy from trusted dealers. Get More info wates pressure vessel supplier in uae. |
