Question
Matt, I'm looking to install a well for irrigation. My yard is L shaped and is approximately 22,000 sf. with 1" PVC coming off the well, how many gpm should i expect at 30psi  40 psi and 50 psi. The reason I ask this is because I want to make sure I get the right size pump for my well.

Thanks

Answer
Thanks for the question.
You didn't mention what size well you have planned. 2", 4" or 5".
I can give you a few general guidelines. You will need a flow rate of 12GPM to 18GPM at 40PSI. Obviously, you can work with more or less, but 12-18 is a good range and is cost efficient. 40PSI is a common pressure pump manufacturers rate there pumps at.
Reply back with the well size and approximate depth to water and I can help you select a pump.
