Water pressure tanks for sale
What is a Pressure Tank ?
It is a tank that consists of a diaphragm or bladder that separates the tank into parts, the compressed air section (upper section for vertical tanks) and the water section (lower section for vertical tanks).
How does it work?
As the pump pushes water into the tank it compresses the air inside the tank's diaphragm. Once water valves are opened inside the house the compressed air pushes the water out of the tank towards the house.
Advantages of Pressure Tank
• It acts as a water reservoir allowing water to be pushed out from the tank without the pump cycling. This protects and increases the lifespan of the pump.
How do I size a Pressure Tank ?
In terms of pressure tanks, size matters, usually, the bigger the better. A tank of the right size prolongs the pumps life by eliminating cycling (turning on and off rapidly which causes the motor to heat up). Big tanks mean a large draw down and therefore less cycles. A minimum runtime of 1 minute is
To size a tank you need the following:
Tank Drawdown = runtime X flow rate Nb: Drawdown is not the same as the tank capacity, it is usually less than the tank capacity.
Can a Water Pressure Tank Explode ?
A pressure tank can explode if the working pressure inside the tank exceed the pressure it was designed for. If the water temperature falls below freezing point a tank may explode. There has been few incidents reported about pressure tanks exploding.
When to Replace/Repair a Water Pressure Tank ?
A ruptured bladder, leakage and water-logging in the tank are some of most common problems experienced with water pressure tanks. The signs below alerts the user that there might be a problem with the tank.
If you notice the above signs you might need to contact a professional to perform further inspections or it means it is time to replace the tank.
