I apologize for not updating, yes I did. The whole house filter was completely jammed up with iron. It was a carbon/sediment filter ($50) and I replaced it with a simple sediment filter and added iron out softener salt. The pressure is much better, not overwhelming but certainly livable.
Today my septic alarm is going off but only kind of lol. The red light is dimly lit and the alarm sounds like a sick chicken or something. When I hit the test button the light gets much brighter and the alarm much louder so I'm not sure what is going on. I removed the lid to the tank and the pump tank (thingy?) and didn't see anything that looked unusual so I'm not sure what's going on.
Septic pump?
(grinder pump)
