Second Floor Demo Prep

With the drainage project finally wrapped up, we’re getting ready to demo the second floor! As in the past, we’re having a demo party where friends come over to smash the hell out of the walls and tear everything down. To make sure this process goes smoothly, safely, and makes as little mess as possible, we have some work to do up front. First, we need to clean up the first floor. With us living in the basement, and the second floor empty, we’re using the first floor as storage. Between all of our projects, moving to the basement, and life in general, it has a tendency to get away from us and turn into a cluttered, disorganized mess. When we demo the floor above, dust and debris are going to rain down between the floorboards, so everything needs to be as contained and protected as we can make it.

I tackled the back (everything behind the wet wall) since this is my de facto workshop where all the tools are kept. After we rushed to finish the basement, I wound up bringing them back up in boxes and not putting them away. I re-organized and cleared out the worst of it, but honestly, I still have a lot more cleanup to do. However, the critical part was I made a space big enough to put all of the kitchen cabinets from upstairs. When we bought the house, we got a bunch of free kitchen cabinets from Sarah’s grandmother (who in turn had gotten them from a friend of Sarah’s parents when they remodeled their kitchen). We’re done with them now, so we’re giving them to Sarah’s parents, since they’ve bought rental property in Florida and want to redo a kitchen down there. Until they pick them up, we needed them off the walls and in the first floor. Sarah cleared up the front of the first floor, which was a bigger process since it involved not just organizing, but throwing away what we don’t want, donating what we don’t use, moving some of what we want into the basement (and finding homes for it all down there), organizing the rest of it into bins and boxes, and finally, covering it all with tarps and drop cloths.

I disconnected the water, which was complicated by the fact we still have the washer and dryer on the first floor and by the way the plumbers replaced a perfectly good dielectric union with a brass female adapter and my side-drain valve with a regular valve (both for no apparent reason other than to piss me off). That meant to disconnect the hot water I had to cut the copper pipe past the valve (which was full of water) and drain it that way. I still need to solder a cap on the pipe. For the cold water (which is all we have for the washer) I was able to reconfigure my press-fit PEX fittings (so easy!). I also disconnected the gas line that went to the stove upstairs. That was made more difficult by the fact it was one 12′ pipe going from the basement to the second floor. Disconnecting it was easy, getting it out of the wet wall was a bit more difficult. We had Lester, our radiant contractor, disconnect and drain the radiators a couple of months ago, so I was able to just lift those off the wall and move them downstairs. I unscrewed the thermostatic valves and fancy stainless steel fittings and saved them in a bag. These radiators will eventually be in the attic bedrooms, since the other stories will have radiant floor heating.

I turned off the electrical circuits for the second floor and took down the ceiling fans and light fixtures, but I still need to remove the actual BX wire cables strewn through the attic. I reclaimed the outlets (few that there were), which we’d installed new when we bought the house. The whole upstairs only had one light switch (in the bathroom) since everything else was on pull chains and a couple of fan remotes. Honestly, one of the nicest parts of the basement is the normal complement of outlets and switches, since they were in short supply upstairs.

Debris chute

Debris chute

Sarah ordered a big dumpster and it was dropped off in the back yard on Friday. Monday I built a chute out of the extension ladder and some 2x4s and plywood to go from the back door of the second floor down to the dumpster that will make the demo process go much faster. We discovered when we demoed the first floor that balloon frame houses lend themselves to a particular order of deconstruction if you want to contain all the plaster dust and mess. By demoing the ceiling first, all the debris falls into the still-enclosed rooms rather than into the wall cavities and into the floor below. By saving the flooring for last, we prevent (some of) the mess raining down between the subfloor boards. Also, by demoing the ceiling before the demo party, we prevent some of the more dangerous aspects of wanton destruction with large groups of people.

I got underway with ceiling demo, starting in the back bedroom and kitchen and working forward. We insulated the attic with blown-in cellulose a few years ago, so there was a lot of fluff shoveling, but the chute is working as hoped. The top of the chute is slightly higher than I’d planned, so I need to lower it a bit, but otherwise it’s a vast time saver over hauling everything down by hand. When we prepped for demo of the first floor we took down all the trim, but in the second floor, at least for the windows, I’m concerned the trim is actually holding the windows in place. They’re all cheap replacement windows and they’re less than professionally installed. We may take it easy on those until we’re ready to replace them. The weather is getting cooler and we don’t want any gaping holes in the exterior walls, let alone the possibility of broken glass and injured people.

I expect to finish ceiling demo tonight, the kids will be out of the house with grandparents for the whole weekend to avoid any noxious dust contamination, and we’ll get this, quite literally, knocked out!

New Gas Plumbing

We’re taking a step back from framing the first floor and shifting to mechanicals. Specifically, getting the new boiler installed in the basement. I met with Lester, our radiant heating guy, on Wednesday and we walked through the plan. I got the requirements figured out for the boiler install and we’ll be working on getting those items ready over the next month and a half.

The first step in the process is the gas line. We need to provide gas service to the new boiler, and given the state of the existing plumbing, it was time to start over. We modified the gas plumbing about a year ago to eliminate the runs along the beam in preparation for the steel beam. With that done, there were still two runs from the meter at the front of the basement to the back. One went to the existing steam boiler and then to the water heater and stove on the second floor while the other went to the gas dryer. It went through byzantine twists, multiple unions, and a frustrating lack of valves. It was time to replace it all.

Putting in all new plumbing meant I needed a plan. I came up with a simple main trunk and branch design that would service all future gas appliances. To determine the sizes needed I added up the distance from the meter to the furthest branch and the total input btu of all appliances. Then I used gas pipe sizing charts to arrive at 1¼” for the main line, reducing to 1″, ¾”, and ½” at various junctions. With the plan in place I worked through the basement, measuring distances and coming up with every pipe length and fitting I’d need.

If I was to do this again I’d recommend going to a plumbing supply store. They sell the more obscure fittings, like reducing tees in all sizes, inline reducing tees, 1¼” street 90s, and on-site pipe cutting. Because I went to a big-box store instead, I had to re-plan in the store, winding up with a lot more fittings, and every junction is  potential leak. In any case, I got home and immediately realized I’d forgotten to buy the straps to attach the pipe to the ceiling. D’oh! I went back, bought the straps, and then laid out everything on the floor and discovered I had gotten a reducing tee by mistake (it was in the wrong bin).

Yesterday morning I ran back to the store and bought the correct tee. I got started removing all of the existing pipe, except for the run up to the stove on the second floor. Then I connected the existing water heater to the branch that went up to the stove, making a single segment that could be removed at a later date.

Dean and Sarah’s dad, Mike, arrived and we set to work putting in the new plumbing. The new trunk runs along the beam, just as the original line did. We got about halfway down (at our second tee) and realized that my measurements hadn’t properly accounted for the size of the couples and tees. We needed a shorter piece of pipe to line up properly and our pipe threader only went up to 1″ pipe. Mike ran back to the hardware store to get it and Dean and I worked on putting the remaining branches together.

Mike got back with the missing pieces and we got the remaining branches in. At the end of the trunk we ran a line to the dryer using existing pipes and fittings. Someday that branch will be removed and in its place we’ll put in a line to the back deck for a natural gas grill.

After requisite leak and pressure testing, we only needed to tighten a couple of unions. Everything was looking good. We re-lit the pilot on the water heater and headed upstairs for some burgers cooked on the gas stove. A big thanks to Dean and Mike for their help!
