The obvious is if the gauge is out of the &good& range but should they be replaced after so many years even if the needle says good?I remember when we moved (I was about 12) my father got all new ones and had me practice with the old ones how to hold/use one in the yard (fun). One of them had no pressure and said &replace& but the others seemed ok.My grandparents have one that I know of but it's at least 20 years old, they had an even older one in the car that didn't work when a brake locked up and caught fire so we had to use a bottle of sport drink insteadI have one that's about 6 years old under my computer desk ever since the mulitple exploding laptop battery recalls
When the alarm goes off, you have approximately 400 gallons of capacity {about 2 days} in your septic pump tank before wastewater starts to back up. False alarms can be caused by Heavy rain storms your pump cannot keep up. Power outage… or disconnected to the pump Broken pump Filters are generally located on the outlet to the leach field. {the second access to the septic, furthest from the home}
It sounds like one or more of the bushings are shot. May even be a body mount bad. Try to wiggle the crap out of the body and listen to hear where it's coming from. If not you will have to drive it until you can make it do it. You can usually roll down the windows and tell approximately where it's coming from. Start looking from that point until you find it.
