i just got a free hot tub from a friend, he said it had a leak but didn't knw where it was coming from, well i found it, it is coming from the vertical water heater core inside the control box. the welds on both the top and bottom had split... well instead of going all out and renting a welder i just put some jb cold weld on it. on the jb weld site it says it can only stand temperatures of 500 degrees so my question is how hot will this heater core get? also i should throw this in too, there are about 5 wires touching the heater that look like thats how it was installed so maybe the surface of it doesn't even get hot? i don't know.. any info is appreciated.
