Hi all, I'm a pretty handy guy, and have done a fair bit of bathroom plumbing amongst other general remodelling of our house. Our HWH is almost 15 years old and being only 40 gallons can not keep up with the demands of the family load, so i figured it was time to replace it. I used some lowe's gift cards, store credits, etc and picked up a US Craftmaster 66 gallon tank. I've helped someone before replace their tank, but the piping on my current HWH has me slightly skeptical of what to do.
If you look at the top of my current HWH in this picture, it is almost standard. Port on left is hot water outlet. Port in center is TPV. Port on right is cold water inlet. You will see that the cold water inlet has a T junction on it. The 'T' branches out into an insulated pipe which then goes into the wall.That can be see in this picture. You can also see they had the drain pipe going into the wall as well.
My question is 'what the heck is that T junction for?' I have yet to see anything like it on any hot water piping diagrams.
I'm tempted to cut away some drywall because I'm curious what they had going on back there.
Thanks in advance, Kevin
