I have an 85' well with a 1/2hp submersible about 14 years old. Static water level about 25'. It has been great for doing my irrigation and domestic until this year.
Now, it works good for my domestic water needs but when I use it for irrigation I suddenly have a problem. When it starts it works fine, but after about 5-10 minutes it dies down and looses pressure and volume. The sprinklers start surging and th pump sounds noisy. Then I have to shut it off to recover.
I've resized my sprinkler nozzles down to a 6-8gpm consumption, and now i can go about 20min before the problem starts again.
Any ideas on where to start?
Thank you in advance.......
