One thing to note before we gain started: my collection up is simple. Ns only have actually one shower and also one sink. I perform not have a washing machine, dishwasher or bathroom sink.

Alright, room you ready? Let’s dive right into Tiny house Plumbing!
To recognize this article, you’ll require to find out the adhering to terms: off-grid, on-grid, fresh water, greywater, and black water. Don’t worry, I’ve identified them all below.
“Off-Grid” VS. “On-Grid”
What carry out these state mean? Off-grid means that you space NOT linked to city water and also that your mechanism is self-contained. You might be off-grid once dry camping or parked on a piece of land there is no city connections. On-grid is when you are linked to city water, such as in one RV park.
I have both off-grid and also on-grid alternatives in my tiny house, which i recommend for flexibility in parking. The course, if you will always have a city water connection, having an off-grid device is no necessary. First, let’s discuss freshwater for both off-grid and also on-grid.
Freshwater is the water you use for drinking, cooking, showering, toilet, washing dishes, etc.
My “Off-Grid” freshwater system
First, let’s talk about my off-grid fresh water system. Because that water storage, ns fill a 46-gallon water tank, i beg your pardon is secured under my kitchen counter. Ns fill this tank by connecting an RV drinking hose (or transferring jugs of water) come my water inlet.
The average American uses between 80 -100 gallons that water a day, so it’s good I am not “average.” I use about 10 gallons of water a day. When ns am off-grid, i fill my tank every 4 days.
Now that we’ve gotten water right into the house, how does the work?
To warm the water, I have a tankless propane water heater, i beg your pardon is extremely efficient. Read an ext about the here. For off-grid water pressure, I usage a water pump. The water pump runs on 12V and also the water heater requires 12V come spark and also to safeguard itself indigenous freezing. My house is wired because that 110, therefore I have a 12V converter to operation these appliances. These elements can easily be it is provided by a gas generator or solar power when off-grid.

My “On-Grid” freshwater system
When i am “on-grid” (connected come city water) i simply attach my RV drinking hose to the gave spigot and yes sir no need to use mine water tank or pump. In the winter, I need to use a heated hose and also insulated spigot. An ext on tiny House winterization here.
Once the city water pressure was so strong it actually damaged my inlet! because then I’ve replaced my inlet’s plastic fittings through brass ones, and also I’ve purchase a pressure regulator.
The plumbing choice for tiny residences is PEX. It’s DIY friendly and also lightweight. Friend will require the PEX piping, crimping tool, brass elbows and also fittings to do the jump yourself.
As a note, I additionally use a low-flow shower head to maintain water. I have actually not found this to it is in a difficulty when washing my hair. I’ll likewise mention that the water pump I initially bought (pictured below) can be a bit loud. I finished up replacing it v this much more expensive and also quieter water pump. Both work-related fine, yet if you want the quieter version, go with the one I simply mentioned.
Greywater is the water that drains out of sinks and also showers
Greywater is not necessarily waste. Ns use biodegradable products for mine soaps, shampoo, conditioner, lotions, etc. Mine greywater is composed of these soaps, my body oils, and food assets diluted v fresh water. If I had actually my very own land, i would produce a drainage mechanism to usage my greywater for irrigating mine garden, comparable to Art’s tiny home system. It’s a great way come recycle!
When I’m off-grid, I usage a portable greywater tank. If I’m on-grid, generally at a campground, I affix to the sewer mechanism with one RV sewer hose.Portable greywater tank
As through fresh water tanks, greywater tanks come in all shapes and also sizes. Mine is just 15 gallons, therefore I need to dump it as soon as a day. I’m in reality glad it’s tiny because I can empty that myself (it weighs nearly 100 pounds as soon as full).
How to dispose of greywater when Off-grid
Where ns dump mine greywater really counts on mine location. If I’m on in ~ a national park, ns dump it in ~ the allocated dump stations. Dump train station are also sometimes accessible at rest stops. If ns in a residential neighborhood, i dump mine greywater in the nearest sewer drain or i ask my organize if I have the right to use it come water their grass. If it’s rain outside, that’s a good time to dump! any smelly food product is quickly washed away by the rain. Think about it this way, most people wash your cars in your driveway. The soaps they space using have actually chemicals that space substantially much more harmful than my greywater.
*As a note, dumping greywater is not legal everywhere. Research study your location and also use your best judgment.Greywater drain and also portable tank
Black Water is the wastewater from a toilet
I don’t have this because I usage a composting toilet! No, it doesn’t stink. Read my complete review.
I did plumb a freshwater line for a possible flush toilet enhancement in the future (in instance I market my house one day). You can see that above my toilet in the below photo.

Dumping black color water
This is a an extremely unenjoyable process. Friend will have to install a black color water tank on your tiny house, and then pay to have it pumped out or drive it come a recording station and do it yourself. Friend can likewise bypass your black color water tank and connect to the drain via an RV sewage system hose.
Guess how you understand when it’s time to dump? Smell…
I’m told the the average permanent RVer needs to dump their black water every two weeks. Ns dump the solids in my composting toilet every 3-4 months. I don’t have actually much an ext to say around black water due to the fact that I don’t have it. My tip is to go waterless through a compost toilet.
