here is the situation
i wired up a septic pumping system 120 volt pump & 3 floats ( pump on, pump off & high level alarm) at a new house, power was not turned on at the house at the time of completion so i couldn't test the system. 3 weeks later when the power is turned on, the high level alarm goes on, homeowner calls the engineer who come out and looks it over and say's the whole system is wired wrong. H/O calls me not to happy about my work, next day i show up and start looking over my work checking to make sure i didn't screw up , made sure the floats ( installed by someone else) were working. thats when i noticed the alarm float was N.C. contacts, so called the engineer back he's out of the office so i talked to his partner he said thats the way it should be. so i spend another hour checking all my connections making sure i didn't miss label a wire. so then i call the manufactor of the system tell them what i have they say the alarm float should be N.O. (what i thought) so i call the engineer back he agrees that the wrong float was installed. so here's the question who should pay for my 3 hours i wasted troubleshooting somebody else's screw up homeowner, engineer, or the people who installed the floats.
