Would love to...but this is new construction about 25 miles away. We get to drive over after work some evenings and see what was done. The trades are gone by the time I get there. I should be able to trace the line this weekend though.Why don't you just ask the plumber what the second hot water line is for. He is right there and can
explain it to you.
It is a logical idea, however, there is another bathtub in the home and it does not get this feature. I guess the plumbing code only requires it for the master? Only the master bath. Wouldn't the kids bath be a better choice for something like this?That’s a cool way of doing things. Here we have to temper the water right at the water heater
You know, that does make sense. I bet a single handle tub cannot deliver full hot water, there is always a little cold mixed in...right?In other words your master tub must have a roman tub faucet. Your other tub must have a single handle
