Adding Auto-Refill to Keurig

It’s not that manually refilling a Keurig tank is hard, it’s just unnecessary. Commercial Keurigs (and some of the high-end home versions) are built with this in mind and can be directly plumbed for water. Our Keurig, however, is a ‘normal’ home machine without provisions for direct plumbing; so some creativity was involved in adapting it for this feature. Altogether this was a fairly simple 3-step process:

#1 – Make bracket from scrap piece of PVC pipe.

#2 – Install miniature float valve ($3 w/ free shipping) and bracket into tank.

#3 – Plumb float valve to existing water filter under sink.

All plumbing is nicely concealed behind the microwave/cabinets, so the only evidence of anything different is the float visible in the tank. Before anyone freaks out about the evil toxic plastic floating in the water, I should point out that the tank itself is plastic anyways, as is much of the tubing that supplies water to the faucet when filling the old-fashioned way. Total project cost was well under $10.

The Bungee Shifter Device

I’ve been driving the bus quite a bit this week and so far all is well. It seems happier/smoother/quieter with each trip. If first gear is selected it works for a foot or two then pops out; if it’s held in first it works for a foot or two then grinds. Although I did clean and reseal the trans I didn’t do anything with the internals and I think they’re just too far gone. Luckily the 1600 has plenty of torque to just start in second all the time; it’s a little tougher on the clutch but I’ll replace it when I replace the trans. Replacing the trans has been part of the plan anyhow, the stock trans requires 4500RPM (redline) in 4th gear to go 65MPH; the replacement will have taller gearing to both allow higher speed and lower the revs at normal speeds.

It pops out of 4th too, which is apparently a very common problem. Since it stays in 4th if held, I’ve solved this by deploying a strategically placed bungee cord anytime it’s in 4th for longer than I feel like holding onto the shifter.
