Choosing the right pressure tank size is essential if you want to have a steady and regular flow of water from your well. Keep the water pressure steady, cut down on pump cycling, and extend the life of your well pump with the help of a pressure tank. In this thorough tutorial, we’ll investigate what goes into deciding on a pressure tank size for your well system, and give you the information you need to make an educated choice.
Understanding the Role of a Pressure Tank
Let’s quickly review the function of a pressure tank in a well water system before delving into the variables that influence tank size. Your well pump will run less frequently since the pressure tank stores its output. This cycle control will keep your pump running smoothly and reliably for years to come.
There is a thin membrane separating the pressure tank’s two sections. Well water is on one side, and air under pressure is on the other. Pressure is generated as water enters the tank and pushes against the air inside. Even when the pump is off, the pressure tank maintains the water system’s pressure at a constant level.
Factors to Consider When Choosing a Pressure Tank Size
Well Pump Capacity: The capacity of your well pump should be taken into account as the first and most important element when choosing a pressure tank size. The rate at which the pump can refuel the pressure tank is determined by its capacity, which is expressed in gallons per minute (GPM). A larger pressure tank is necessary for a well pump with a greater GPM in order to handle the water flow without creating excessive cycling.
Water Demand: Another important consideration is how much water your household uses. The number of people, restrooms, water-using devices, and fixtures should all be taken into account. A larger pressure tank will likely be required by a larger household with a higher water demand in order to guarantee a sufficient water supply during times of peak usage.
Cycling Frequency: A pressure tank’s main objective is to lessen the frequency of pump cycling. When a pressure tank is too small in comparison to your water demand, the pump frequently begins and stops, which causes the pump motor and switches to prematurely wear out. A properly constructed pressure tank reduces these cycles, thereby extending the pump’s life.
Drawdown Capacity: The amount of water that can be removed from the tank without triggering the pump is referred to as the drawdown capacity. Unexpected spikes in water demand can be met without starting the pump by using a larger pressure tank with a higher drain capacity. For houses with high-flow equipment like washing machines, this is especially crucial.
Minimum Run Time: Well pumps must run for a set amount of time in order to function properly and prevent excessive wear. Longer intervals between pump cycles and the ability to run the pump for longer periods of time are benefits that a larger pressure tank can bring.
