Following up on our last article seen HERE , I’m going to start off with a brief overview of what’s been happening with our water heater..
On demand water heater update:
After reading the portable eccotempt L5 horror stories, we decided to shy away from using the one we had. After days/weeks/ months of reading mixed reviews for the other models, we decided to invest in a good one. We ordered the Takagi T-KJr2-IN-LP Indoor Tankless water heater ($843.41 on Amazon) because of the wonderful feedback. Unfortunately it came damaged in the mail. more “What about water in -40?

Hey folks. I thought I would do a little write up on our “composting toilet” and sum up the concept for any newbies out there.
Composting toilets are basic little units. You can buy fancy ones like these:
Or you can make your own like this:
Or you can rough it like this:
We made ours like this:
It’s all the same idea.
A bucket, container, bin, (whatever) collects your waste and then you compost it. Not a complicated process at all. After you “do your business” the fecal matter is covered with some sort of organic material. Cover materials include corn husks, rice hulls, shredded junk mail, leaves, and peat moss. We use a mixture of sawdust and scrap coffee and tea grounds. The cover materials insure that there is no smell and they aid in the composting process.
Most people choose to separate waste from urine, though the humanmanure handbook discourages it. Urine is heavy and requires a lot of sawdust so we choose to run it outside and directly into our compost bin. Almost all commercial models are designed to separate.
Fancier commercial designs may include a fan to dry out the waste, shrinking it, so the unit needs to be emptied less often. There are also units with cranks in place so you can rotate the pile. Some models require the use of enzymes and deposit fresh soil out of the bottom.
We purchased the Separett Privy 500 toilet setup which diverts the urine from the feces by catching it in the front and funneling it away. I’m going to outline our design so that potential toilet DIYers don’t stumble upon the same problem we did.
The separett toilet seat came with the design outline seen here. If you buy the seat, DO NOT use the minimum requirements. This is our fix and another one can be seen here. The minimum requirements will make you a cute little unit, but you will not be able to remove the bucket when the time comes… Unfortunately, it is not as easy to “disconnect the pipe” as the website promises. For us, it was nearly impossible. I literally shredded the end of the hose attempting to pull it apart. Our bathroom is quite small and does not permit us the space to remove the bucket through the side of the toilet. We had to find another solution.
First, we sawed off the threading on the hose connector so that the hose could easily pop in and out of place. I found an industrial clamp that fit perfectly around the pipe and the hose. I built a hinged door in the front so we could access the urine clamp. I also added hinges to the top so that once the bucket is full, and the clamp is disconnected, we can simply swing up the top and remove the bucket.
The back draft solution.
With a gentle breeze, the smell of urine and cold air (REALLY COLD AIR) was drafting into our bathroom. With advice from this guide http://www.wecf.eu/cms/download/2007/WP-26_web-07.pdf , I made some modifications and created a “trap”. The trap is a section cut from a rubber exercise band with a small hole in the center. It provides enough room for the urine to pass through while preventing a back draft.
Finally, we purchased a standard toilet seat to replace the Styrofoam one that came with our separett. We sawed off the screws so that they could be inserted into the wood holes that we drilled. This way the seat can be removed whenever we need to flip the top up to access the bucket.
And voila! We now have ourselves a composting toilet AKA a poop bucket. We’ve been using it since we moved into our home and couldn’t be happier. Our original plan to eventually replace it with a “better model” has been foiled. This is all we need.

Today we ordered one of the most expensive investments for our home. We settled on the Takagi T-KJr2-IN-LP Indoor Tankless water heater. Selecting such an expensive unit was a rather dramatic shift from our original Eccotemp L5 “Portable Tankless Water heater and Outdoor shower”.
Prince Edward Island is leaps and bounds ahead of most of Canada with the alternative housing movement. I recently had the privilege of connecting with Earthship extraordinaire, Jayden Charlton. He has worked alongside his build partner, Jordan Cameron to nurture Earthship PEI from an idea into a full grown movement. more “Inspiration and motivation: An interview with Earthship PEI”…
