I had my pool guy take out my pool/spa heater because it was old and didn't heat the spa quick enough. I got a new one and it's ready except for the gas line. There's the pipe that was already run out to the old heater about a foot away from my new heater but I need it connected. Does anyone about how much something like this should cost? I was just quoted 500.00. I about shit my pants when the guy told me. I guess we always have an amount in our heads of what we think it will cost and that wasn't close to what I was thinking. The guy has to turn off my gas, unscrew a cap on my gas pipe that run out to it already, screw another line on to that pipe and run that line to the heater 1 foot away and then turn my gas back on. Maybe that's not it but I watched my pool guy take it out and it doesn't seem like much more than that.
