You may think that you don't need a pressure tank at home, but there are times when these tanks prove to be invaluable. Pressure tanks are more in use commercially in water treatment plants and this is the reason people don't tend to think about them. However, there are households that have pressure tanks installed and they find great use of these tanks. What are the basics of pressure tanks and why they may be useful to households?
What are pressure tanks for?
A pressure tank is like a normal tank but with the capability to pump water. The primary purpose of one such tank is to ensure that your household is never short of running water. If you receive your water supply from the city's supply system the pressure of water is maintained but if you are dependent on well you would need a pressure tank to maintain the steady flow of water.
How do these pressure tanks work?
Pressure tanks are a part of water well system that produces pressure on the water with the help of compressed air. They work as the reservoirs for your home. When water is turned on in your home, the compressed air inside your home water tank pushes the water out to the fixture you have turned on. As the water inside the tank reduces, the water and air pressures in the tank come down.
The pressure control switch of the pressure tank senses this drop in pressure and the pump then pushes in water to the tank from the reservoir. The pressure is kept within a range of 40 to 60 PSI. So, when the pressure drops below 40 PSI, the pump in it starts to bring the pressure back to 60 PSI. This replenishment process goes on till the original water and air pressures levels are reached.
What are the types of pressure tanks?
The water tanks with pressure pumps can be of two types: air-over-water tanks and diaphragm-based tanks, also known as pre-charged bladder tanks. The first types are standard hollow tanks that you need to physically charge with air from time to time.
Diaphragm tanks have a diaphragm or bladder that can hold a fixed amount of air inside and this air is pre charged. The water inside the tank is actually separated from this pre-charged air. The diaphragm tanks are considered to be more convenient to use because they don't need manual recharge. These tanks are also considered to be more reliable since they don't need a lot of maintenance. These tanks can be made of fiberglass or steel.
Can these tanks be recycled?
Pressure tanks can be recycled like any other recyclable item. If you have a steel pressure tank, you can recycle the steel as well.Share
