Forum Title: Hot water tank safety valve
Hello More questions on my new construction ; Ok so I am installing my hot water tank in the basement centrally located..pretty much in the middle of the area. I can not figure out how to plumb the overflow pipe for the safety blo off valve so it will exit the basement above grade. The only part of the basement that is near grade is 25' from the tank. This basement has no under slab plumbing since it started out as a very tall crawl space and then I poured a floor after the fact. I don't think code will let me just direct to a drain pan because then the pan will require and exit drain. Stumped again..thanks

it can drain into a floor drain, if no floor drain is available, move the heater

Stumped again..thanks you can run the pipe horizontal,with slope, but you can NOT go UP it is a drain, under no circumstances can it be piped UP the pan drain must also be piped to a floor drain or outside

Thanks but there is virtually no other place to locate the tank because our open floor plan prevents optional venting except the central location. So to ask my first question again: can the blo off pipe be routed 15,-20' feet sloping to an exterior wall? Thanks for your help. Jim
