Domestic Well and/or Well Pump issues

[NFATrustGuy]

I recently bought a house in rural Brighton / unincorporated Adams County. For the first time in my life, I am dealing with a well and septic system.

The water smelled like sulpher, so a friend suggested I flush the Well with bleach. I did that a couple of days ago. The smell is almost gone and seems to be getting better each day. In the process, I managed to dork something up.

My pressure accumulator and well pump seems to regulate the system to between 53 psi and 65 psi when I’m using household faucets and the shower. However... when I try to run the sprinkler system, the pressure drops to 20 psi and the well pump can’t regain the pressure. 20 psi isn’t enough to run the sprinkler system so the heads kinda just gurgle rather than actually shooting water. (All these sprinkler issues happen even when there’s no other water running anywhere in the system.)

Does anyone have any suggestions for troubleshooting? In the alternative, is anyone on this forum a Well expert who has time to come help me out. Not asking for a freebie. I’d just rather hire someone on a referral rather than throwing darts at Google.

Thanks in advance. I’m near Bromley and Gun Club Road.
