How We Calculate a Well Pump Size
Its actually pretty easy for RPS to give you a straightforward answer on the type and size of well pump you'll need. Just provide the following information...

1
Well Depth
A general estimate of your total well depth is all you need to get started!
2
Using a Pressure Tank
Most households and irrigation projects use a pressure tank (usually blue or grey tank that sits close to your well).
3
Gallons Per Minute
Do you have an old pump that you're replacing to base the flow rate off of? Maybe you know that your well only produces 5GPM, so we should stick around that number. And for most households, between 15-25GPM is typical.
