Hello, this is my first post. I am not a plumber, but I have had to do some plumbing work in the past and can sweat copper and use pipe dope so I can barely get by. I also have some electrical background so can do that myself with some level of confidence.
With that being said, I am trying to relocate my water heater location and change over to an electric tankless from a gas tank. (tank broke last night and flooded the garage). The purpose is the put the location of teh new tankless as close to the shower since the existing tank stubouts are at the farthest point away in the garage. My question is, if I tie into an existing water line in the wall behind the tub/shower area, and run the appropriate electrical to the new tankless heater, would there be any issue with making this the new hot water source? The plan is to use the cold water line by adding a 1/2" copper "T" and that would be the input to the new water heater. The output would go to the existing hot water line for the tub, adding another copper "T" and then tieing the old lines together in the garage (output to input). Does anyone have any advice for the new installation? Sorry for the long winded question but wanted to get the full story out there.
thanks in advance!
