Q: pump rattle - SHURFLO 4008-101-A65 Revolution

After a few months of very intermittent use it developed a rattling noise on low flow or before shutting down. Here is the noise, phone mike makes it more "rattling" than it is: https://youtu.be/S2Pte...

How are you getting pressure on the intake side of the pump? Stuttering on shut down could be leaking check valve or erratic pressure switch. Also how is the voltage at the pump?
