I posted this on the plumbing forum but not here. I had to replace our water heater last week.
I had the luxury of time because, most of our house, is served by a tankless heater but the water heater that I replaced is only used for the clothes washer and one bathroom that doesn’t get used much.
I really wanted to clean up the plumbing around the WH so I ended up cutting into the wall behind it. The utility room, where this WH is, was added on at some point in time, so the wall behind the heater used to be an exterior wall.
The Pex coming down from the attic is there because the old, original galvanized pipe that came from the main house, broke under the slab. I just bypassed it through the attic.
Besides the connection to the house through the attic, there are also old CPVC pipes that connect the WH to the washer and also the bathroom on the other side of the wall. I found that the old CPVC is a little brittle so I carefully cut it with a Dremel style tool. (Notice, the hot is the blue pipe and the cold is red).
I used sharkbite elbows to transition from the CPVC to the Pex and ran the Pex upward inside the wall. The CPVC originally came out of the wall here and ran up the outside of the wall to the WH.
I added an electric shutoff switch (per code) and two 18” flexible stainless connectors between the tank and the new plumbing.
I decided to hang my expansion tank with the water on the bottom and the air on top. I just feel better with the water on the bottom, however, I realize that if I have to change out the expansion tank, it will be a mess.
I used two dog-eared Pex to Female pipe thread elbows, screwed into the wall, to make my connections sturdy.
I put a pan under the WH although there is not a good way to hook the pan to a drain.
That white pipe to the right of the WH is a dip-tube I bought for the old WH but it wasn’t needed and so I never installed it.
I was thinking about how to get rid of the old WH and Ruby says, “I’ll just put it on FB MarketPlace for free. It will be gone in no time!”
I thought, who would want an old WH that leaks? I told Ruby to be sure to state that it leaks in the FB Market post and she did. We had 15 people within minutes that wanted it. The first guy was a flake so she went with the #2 guy and he came out the next morning and picked it up. I didn’t get to ask him what he was going to do with it though.
