This was probably the most complicated planning effort required in the basement remodel. I knew that the basement would have a new hot water heater (HWH), new bathroom, new laundry area, and new wet bar. I also wanted to run water up for a future refrigerator upgrade in the kitchen. And I also wanted to run gas up for a future stove upgrade. And to reduce pipe clutter in the ceiling. And I knew that these things were somehow all connected. But where to start?

Well, how about with a picture? In the distance, you can see the old HVAC and HWH at the end of the basement. The joists above (and the water main) run from the front of the house (to the right) to the back of the house (to the left). The wet area, where the new HWH needed to be, is about middle-ground in the photo, and against the far left wall.

Demolition almost complete. HVAC and HWH, c. 2005

I started by taking a piece of 24″x36″ sketch pad paper and drawing a scale image of the joists above, then I marked each vertical pipe run up to he first floor (two for each faucet, 1 for each toilet; a total of 8). I then sketched in the horizontal runs that connected them. I then started to sketch in the new basement plumbing plan. Then I tried to marry the two systems together.

Since the HWH was moving, all the runs to the hot water outlets changed. Since the HWH is one of the first off-ramps from the water main, the main needed to be adjusted and that affected all the runs to the cold water outlets.

It took several drafts, and a lot of denial about the amount of work ahead, to get to a final plan.

Ultimately, I ended cutting each vertical pipe to the upstairs outlets and re-running copper to them, thus replacing almost all the copper supply lines in the house.

Only the vertical up to the first floor is original. All the horizontal is new.

But, I had to do it in a staged fashion, making sure at the end of each day that I had water in the kitchen and at least one bathroom upstairs. So, I ended up capping and re-opening pipes, doing a bit more work than necessary, but at least I never ended up in a hotel taking a shower.

Capping things off at the end of each day.

Staying in service.

While researching the HWH install, I learned there are codes for such things as how far away from the tank the supply shut-off valve needs to be. That’s something you don’t want to have to do over. Also, being an electric HWH, I had to run a 220-volt electric line over to the unit. And, there’s code about that too. The electric supply either needs a shut-off switch at the HWH, or a lock on the breaker so it can be locked OFF during maintenance. I went with the locked breaker – it gives a cleaner look at the unit. What? you think it’s silly, considering aesthetics in a utility room? Well, if you eschew aesthetics in a utility room, where will the eschewing end? I ask you.

And you also need to install what they call a “union” in both the cold-in pipe and the hot-out pipe, just above the tank. These are basically threaded couplings which allow the entire tank to be removed if necessary.

It occurred to me that if I installed the HWH as one of the first steps in the project, I’d have to somehow get the finished flooring under it months (years) later. So I decided to make a tile choice, buy all the tiles (they discontinue them, you know), and lay some tiles in that spot first (which meant I had to buy all the supplies and tools for tiling, and learn how to use them, much sooner than expected).

A tiling note here: There’s a floor drain nearby and the floor slopes toward it. Since I needed the tiles beneath HWH to be level, the amount of tile-sticking-substance I would use beneath them would get thicker toward the drain. I tried mastic first, and it didn’t dry at all. The tiles were still squishy a week later. So I yanked it all up and used thinset mortar, which dried rock hard in about a day.

The next three photos shows the installed HWH. Look closely, and you can see some white 1′ x 1′  ceramic tiles laid in a diagonal pattern beneath it. You can also see the power line running from the studs at the left to the top of the unit. and the copper in/out lines running vertically upward.

A few finished tiles in place means no moving the HWH.

Oh, and choosing the HWH? Um, I just went to Home Depot, grabbed one, and threw it in the back of the SUV. It’s worked well so far, except for a year or so later when the control board flipped out. But it was under warranty, and they sent me a new one overnight. Only one cold shower was endured.

Replacing the HWH control board.

I’ve repeated the next two pictures from above, then added a final view. They were all taken from basically the same spot, so they show the progression. In the first photo, the HWH will go where the laundry basket is sitting.

Oh, you noticed the lighter-colored concrete tracks on the floor in the first two photos? Right. Well. You are paying attention, aren’t you. I’m sure I don’t need to tell you. You already thought, wait, he’s putting in a new bathroom, laundry room, and wet bar in the basement. And the you thought, that means there are going to be a lot of new water supply lines. And then, in your inimitably logical fasion, you thought, that means… yes… the water will have to go somewhere! Good for you. Drains. What they call groundwork. In a basement, it has to go under the slab. Cutting is involved. And yes, that work was done before all the stuff I just described. But you already knew that, didn’t you?. I just didn’t feel like writing about it in order. More to come. Stay tuned.

One morning in 2002, I woke up and walked into my home office (the front bedroom) to find the room full of what appeared to be ants with wings. After freaking out for a few minutes, I put a few in a plastic container for further research and attacked them with the shop•vac. I then examined my captives, checked the web, and discovered that they were termite swarmers. It turns out the slow drip had created a yard-deep bog in the front planting bed, which was a perfect habitat for termites. They entered through the foundation, made their way into the office, and… well… swarmed.

The old hose bib was soldered in place, so I had to replace it and the pipe leading to it. The shiny copper on the left in the following photo is the new run that I grafted into the main. Up top, you can see the capped-off T joint where the old hose bib off-ramp used to be. The black wire attached to the pipe is the house’s electrical ground coming from the breaker box about 25 feet away. It wasn’t exposed like that originally – I had to remove it as part of the plumbing work, so I ran a temporary ground that I knew I would replace… someday.

You can also tell from the way I ripped into the wall that, even way back in 2002, I was planning on tearing out the basement and doing something different with it.

Water main (c. 2002)

Anyway, the water main travels up the wall and across the ceiling to the “wet area” at the back of the house. The wet area is where all the water sources and drains in the house are grouped: in the basement, the washer, tub, and bathroom; upstairs, the master and hall bathrooms and the kitchen sink. In the following photo, which was taken during the basement renovation, you can see the same water main climbing the wall, then, after rightward and upward jogs, running parallel to the joists towards the back of the house. You can also see a couple of blocks of new wood attached to the joist and to which the main is clamped. Originally, the main was just hanging loose against the old drop ceiling. Once I started on the basement renovation, I cut it out, adjusted the pipes at both ends, then re-installed it.

Water main headed back toward the wet area

Originally, the furnace and the hot water were located at one end of the house. There’s a fireplace upstairs, and the flue extends to the basement. The furnace and hot water heater were both gas, and they vented into the flue. Also, the gas main is in the corner right next to them, so the interior gas distribution didn’t have far to go.

The original furnace and hot water heater (c. 1999)

All of this is the long way of saying that where the water was heated wasn’t near where it was needed. There was about 45 feet of pipe run between them, which meant a long time waiting for hot water, a lot of water wasted, and a lot of pipe clutter overhead.

Pipe clutter.

Let’s see, what else? Well, the water heater was almost 20 years old, so it needed replacing anyway. Also, and this is fodder for another post, the low ceiling and even lower HVAC duct work meant I wanted a new HVAC solution, and if I was going to move that, I might as well move the water heater and free up that floor space for some other purpose.

And, the positioning of the washer/dryer/tub and bathroom in the old basement didn’t fit my new plan. So, the plumbing to-do list looked like this:

• While moving the HVAC, move the hot water heater also. Get it closer to the wet area.
• Reduce pipe clutter across the ceiling in the utility room
• Since gas work has to be done for the HVAC and water heater moves, run a line up under the kitchen in case, if I ever renovate the kitchen, I want a gas oven/stove
• Chop out all the current bathroom and utility room drainwork under the slab and re-run for a relocated bathroom, relocated washer/tub, and wet bar.
• Run copper and drains for the new utility room, bathroom, and wet bar. While I’m at it:
  • Re-do the runs for the 2 hose bibs in the back of the house.
  • Run a line up into the kitchen behind the refrigerator in case, if I ever renovate the kitchen, I get a refrigerator that dispenses ice and water

Oh, and do all of this in such a way that, at the end of each day, you still have hot water (any water) in the kitchen and at least one bathroom upstairs.

Without any actual plumbing skills.

Sounds like fun.
