How to size and select a proper expansion tank?
- Using the calculated acceptance volume and the calculated total volume, select a tank from the chart to the right. ...
- A pressure reducing valve should be installed on the supply when system pressure exceeds 80psi.
- To accommodate the thermal expansion required for higher temperature and/or higher pressure systems, multiple tanks may be used. ...
Does a well system require a water expansion tank?
No. If you do have another check valve then you would need an additional expansion tank also. Code requires an expansion tank only if the system is closed, this absorbs excess pressure as the water heats. That second valve would make it a closed system and keep your well tank from absorbing that pressure.
What size pipe to expansion tank?

How do you size a well expansion tank?
When selecting a pressure tank, certain information must be known: (1) system demand; (2) pump capacity; and (3) well capacity. bathrooms (half baths are considered as 1) and multiplying by 4 gpm. For a home with 2 ½ bathrooms, multiply 3 x 4 gpm = 12 gpm.
Can a well pressure tank be too big?
The downsides to a larger tank are simply that it costs more and takes up more space. The only real problem is if you have too small of a tank you'll cause the pump to cycle too quickly which wears it out faster.
What is the best size pressure tank for a well?
The minimum runtime rule of thumb is any pump operating at 10 gallons per minute (GPM) or under should be producing one gallon per minute of runtime. (For example, 10 GPM flow rate x 1 = 10 gallon drawdown capacity.) Anything above 10 GPM should be producing 1.5 gallons per minute of runtime.
How big should my well storage tank be?
For large properties with significant landscaping and a large home we recommend a minimum of 10,000 gallons. For smaller properties and homes that don't have to worry about fire considerations, 2500-3000 gallons is a common tank tank that will give you plenty of water for daily needs.
Is it better to have a bigger water pressure tank?
When it comes to pressure tanks, bigger is almost always better. A pressure tank creates water pressure by using compressed air to bear down on the water.
What are the advantages to a larger pressure tank?
The benefit of a larger tank is less electrical consumption due to reduced pump cycling, which also reduces premature wear and tear on the pump, switches, and control components. It is not unusual to see pumps lasting 15, 20, and in one case 37 years.
How do you know what size bladder tank you need?
General Rule of Thumb for Sizing a Pressure Tank0-10 GPM: 1 gallon of drawdown per 1 GPM of flow.10-20 GPM: 1.5 gallons of drawdown per 1 GPM of flow.20 GPM+: 2 gallons of drawdown per 1 GPM of flow.
How do you size a tank?
Measure the height and radius of the tank. The radius is the distance from the center of the tank to its outer edge. Another way to find the radius is to divide the diameter, or width, by two. Square the radius by multiplying the radius times itself and then multiply it by 3.1416, which is the constant pi.
How long does a Wellmate pressure tank last?
It is a type of tank containing pressurized air and water separated by a membrane (bladder) and pre-charged with air at the factory. On average, a bladder pressure tank lasts 5–7 years.
What size tank do I need?
Start with Your Household Size A general way to estimate how much water you may need is to factor 12 gallons of water for each person in your household. The average family consists of two adults and 2.5 children. So, for a family of 4–5 people, you will need to get a tank that is able to hold at least 50–60 gallons.
How many gallon water tank do I need?
For 1 to 2 people: 30-40 gallons. For 2 to 3 people: 40-50 gallons. For 3 to 4 people: 50-60 gallons. For 5+ people: 60-80 gallons.
Can you use 2 pressure tanks?
In short, you can have as many pressure tanks as you like. Locating them closer to the point of use (the house) would be helpful, to a limited extent. That limited extent is the "effective volume" of the pressure tank at the house - while it's got pressure, you get better pressure at the house.
What is a tank?
A tank can be viewed as a container of air and water. The goal in sizing a tank is to make sure the air side is large enough so that when the desired amount of water is put in the tank, the air is not compressed to a pressure greater than system design.
What is acceptance volume in a bladder tank?
In a bladder tank, the acceptance volume is the volume of water that the bladder is designed to hold, which is smaller than the overall tank size. Keep in mind that the tank has pressurized air inside it and therefore it is not possible to fill the entire tank with water.
