Your home depends on its deep well system to provide fresh, clean water for your family. One of the most vital components of this system is the pressure tank, as it stores water pumped from the well and maintains the pressure at which the water flows out of the tank and into your plumbing. This way, the deep well pump doesn’t have to keep running to supply water. To ensure you have the right tank size for your water needs, review the factors that go into sizing a pressure tank below. 

3 Factors that Determine the Right Pressure Tank Size for a Well

1. Runtime

Runtime refers to the amount of time that the deep well pump has to run a cycle and draw more water from the well. If your deep well pump has to run frequently, it will develop wear and tear more quickly and require replacement sooner. To avoid this problem, it's important to select a pressure tank that is properly sized for your home, which will minimize the amount of time the pump has to run. A well pump specialist can evaluate your pump and determine the appropriate tank based on your well's current average runtime. 

2. Water Pump’s Flow Rate

Well pumps have a flow rate, which refers to the amount of water they can pump out per minute. This is usually measured in gallons per minute (GPM). The flow rate affects how much water the tank gets per cycle and how many cycles the pump has to run to fill the tank. As a result, the size of your pressure tank will depend in part on how much water your pump can flow into the tank at a time.

3. Drawdown Capacity

In pressure tanks, the drawdown capacity rating is the amount of water that the tank can store before the pressure gets too low to transport water to the plumbing system. The deep well pump will activate once this happens. It's important to select a tank with the correct drawdown capacity to ensure that the pump doesn't have to constantly work. Luckily, a well pump specialist can help you calculate how much water your household regularly uses to determine the appropriate drawdown capacity for your home.
