I’m doing several projects concurrently right now, I’ll do my best to keep updating. Only one project per update to keep it organized.
First project - grey water tank. (Gray?, Grey?)
I like figuring stuff out on my own but if you see a good solution someone else took the time to figure out, why not use it?
I’m far from the first person to use 8020 style extrusions. When I started using it back in 2018 my inspiration came from Geek’s sprinter -

And the original 8020 van from Orton -

All of my 8020 design work was done before I started watching Ken’s clean build at
https://ourkaravan.com He did an amazing job and I share his site with anyone interested in building a sprinter.
Back to the grey water tank - I’m totally copying Ken’s idea using 8” PVC pipe.

A 40” section of 8” pipe will fit perfectly on the drivers side. I’m running 1 1/2” PVC from the sink drain, though the floor, into the tank and as a drain.
tank goes here:
I was lucky to get a free section of SDR35 sewer drain pipe. Unfortunately, the OD of SDR35 is smaller than schedule 40 and I didn’t know that until I got the rest of my parts. The gap is too big to make the end caps work so I ended up ordering a 10’ long section of 8” schedule 40 pipe that was definitely not free. After this is over I’m interested in selling the remaining pipe to someone local.
I ordered end caps from the not-so-local hardware store where I buy my orange buckets for picking mushrooms.

I also ordered two 1 1/2” fittings: Spears 438 Series PVC Pipe Fitting, Bushing, Schedule 40, White, 2" Spigot x 1-1/2" NPT Female from Amazon. I’m having trouble pasting amazon links but you can easily google those words.
And a Valterra Dump Valve - 1.5 Inch.

After it’s installed and working I’m going to put a motorized auto-drain on the outlet so I can easily drop my grey water.
I’m not putting a household sink drain trap under the sink. I’m using a HEPVO 1-1/2" Trap

There is still one thing I haven’t figured out.
What’s the best way to put the drain pipe through the van floor? I could just drill a big hole and seal it up with silicone but I bet there’s a better way to do it.
