Basement stairs that don't suck

 One of the big projects that's continually gotten delayed is installing finish stair treads and risers. We've been using the original 2x12 rough lumber installed by the framers.


The original stair treads were 2x12 standard dimensional lumber installed by the framers. They were covered in drywall spray and paint, and some of them had cracked. To make them a little more bearable, we had covered some of them with rubber protectors (which my wife hated).

As I researched buying finish stair treads online, I realized that they are expensive and also the wrong dimension, usually 1" to 1.25" thick. I needed 1.5" finish stock to match the rise of the lumber treads. After looking around online and going in to the exotic lumber store in Seattle to price their stock, I realized I needed a different solution. Once again, HomeDepot came through. I found 10 foot butcher block counter tops made out of Acacia much less expensive. Also, in keeping with my strategy of making things just a little bit "different", I felt like these would be more original and beautiful. 


I cut the countertops in to 40 inch sections, then ripped each section to 11.5" to match the dimensions of the rough treads. 

For the risers, I decided to go with 1/4" thick, black HDPE (high density polyyethylene), ordered from ePlastics. I ordered a full sheet and paid for them to cut it in to riser-sizes. 49 cuts out of the sheet only cost an additional $30 to the order. About $235 total landed cost for the risers -- well worth it. 

The bigger task was removing the existing treads and risers. The framers got a little carried away with their air nailer on some treads and risers -- 5 nails through a tread into a tringer...! Needless to say, tearing off the treads and risers was an exhausting 5 hour job.

6 treads and risers removed.

All treads and risers removed.

During the tear out, some of the corners forming some of the steps on the stringers broke off. I had to glue-and-screw them. I then temporarily screwed back on each tread with a single screw to temporarily keep it in place until the new treads could be installed.

I got Rudy's help to finish them with a couple clear coats of water-based eurethane. Applying the eurethan sealer was done over 2 weekends. 


After a second coat of eurethane, I stacked them to dry in the garage.

I purchased black, flathead screws for the risers, and larger black structural screws for the treads.

Overall, pretty please with the result. And gratified to have that project out of the way. Applying the finish/sealer to the treads and the tearout happened on 2 Saturdays. Then installation of the new treads and risers took portions of three days. Over about a month period, culminating on July 1st.

Snow Season Summary 2022-23

The end-of-season charts showing snow on the ground near KnArrow Haus using data from Northwest Avalance Center (nwac.us). Both of these charts use the same data - the white line shows the accumulated snow on the ground.

It was what I'd characterize as a statistically average snowfall season. And the meltout occured a little earlier than average due to warmer-than-average weather.

Adding a Backup Water Supply

The community water system is old. The main system (well, tank and pumps) is only about 20 years old, but the pipes in the groud that connect all the homes are over 50 years old. Even when no one is using any water, the system leaks a couple gallons a minute. 

Every year, sometimes several times a year, there's a bigger leak somewhere in the system requing the pressure pumps be turned off until the leak can be found, isolated, and fixed. Last year it was a leak on a cabin in Division 1, and later sink in a cabin in Division 2.  This year it was a brand new connection to a cabin under construction. Whatever the reason, when the pressure pumps are turned off, water pressure to KnArrow Haus drops to a trickle. Not very useful if you want to take a shower, run the dishwasher, or flush a toilet. 

After a several-week pressure outage last year, one of the long-time neighbors just down the hill showed me the backup tank and system he designed and installed many years ago to the combat the problem. I took videos and pictures of his system, then spent a few weeks thinking about and designing my system. Putting the system in was my Summer 2022 cabin project.

Design for KnArrow Haus backup tank and pressure pump.
I used this to build my shopping list.

The system incorporates a water tank and a pressure pump to supply water if the system pressure is low or off. The tank automatically fills, allowing the backup tank to do what I call "a lazy fill" when the pressure is low. A auxiliary water pump provides pressures the system on-demand, but only when the main system pressure is low. When the main system pressure is high, the pump never turns on.

I can drain the whole house's system in to the tank if needed. And we also get the added benefit that we can close the main shutoff to the house when we leave but still run the dishwasher before we walk out the door.  If the house were to spring a leak or burst a pipe while we're gone, only the water in the tank would spill in to the house, but no more.

Preparing the tank shutoff

The fill valve for the tank is essentially a toilet-style float valve, only bigger. Instead of the typical half-inch flow, it is a one-inch valve designed for larger tanks so they can fill quickly.

The drain valve at the bottom of the tank connects to the pressure pump,
and it has a shutoff tee so the tank can be drained if needed

I built a small bench from scrap wood to raise the pressure pump off the floor

Doing a tight loop with one inch PEX isn't very easy.
This was the final connection I made to the system.

The new backup system all plumbed in a ready for service.

Of course, with every new system it seems like there's always something that fails.  In my case, there were actually 2 things that failed after connecting it all up at the end of the Summer. 

The first failure was one of the two sharkbite pressure valves. One had a slow drip that I could never get to fully seal. I tried disconnecting and reseating it several times, and even tried cleaning up the end of the PEX pipe. Nothing work so I simply removed it and replaced it with PEX. I cannot check the pressure of the outside water system now, but it's not a major loss. 

The second failure was the through-hull fitting at the top of the tank. About a month ago, right after we turned on the main to the house, Katie told me water was dripping all over the floor. I ran downstairs and realized the connection through the top of the tank had broken.

The through-hull fitting at the top of the tank that broke. 
In this picture you can see the shutoff valve on top of the tank
that I had to fish out form the bottom.

The brass fitting through the tank snapped in half. Probably because I overtightened it. 

The new nylon fitting I bought required a much bigger hole in the tank

New through-hull fitting connected. System restored.

Now that everything is back and restored to working condition, I've reevaluated what else can go wrong. The one weakness in the entire design that I can think is the float valve itself could fail. If for some reason it were to fail meaning "not shut off" -- which would only happen while we are there with the main water turned on to the house -- it could cause the tank to overfill and leak water all over the basement floor. Again, this would only happen while were are there with the water turned on. There is no drain in the basement floor...

I guess you'll hear from me again on this subject if/when that happens.
