I just bought a house "as is", and has been vacant for anywhere from 1 to 3 years, and the major issue we've ran into so far has been the water systems.
It's a 1993 house with a water heater that's propane fueled, and whenever we light the pilot light, we start hearing "tink" / bubbling / some sort of noise that sounds like metal expansion or some other horrific problem. It happens within 1 minute of the pilot light being lit and the heater cranked up, and immediately stops when the heater is turned off again.
My father in law took a stab at guessing that there is significant calcium buildup in the tank because it's been sitting off for so long, and is on southeast Nebraska well water. There have been a number of faucets that wouldn't work due to buildup in the aerator, and we've noticed that same issue everywhere. The water softener has been without salt for 1-3 years as well.
I guess what I'm looking for advice on is - is it safe to run until I can get someone out to inspect it? Do I NEED to get someone to inspect it? Is salting the softener and waiting a few days good enough??
I have a video I can't see to attach on mobile, so I'll try and post it after I post this.
All I can figure out is to put it on Google drive...
