Every tiny home build involves some form of tiny house plumbing setup. This is the one thing where tiny houses are different from regular houses.

But tiny houses are portable, and there is no guarantee that you will always get a water source near your house. So, now you must be wondering how to do plumbing for a new tiny house? You can get scared to install it. It can seem very difficult to install, but it is a lot easier than it looks at first glance.

There are a lot of options for water supply and drainage systems for your tiny house. They are really easy to set up and maintain. In this article, we will help you to know how to do plumbing for a new tiny house in a very easy way.

How to map tiny house plumbing systems?

When it comes to plumbing, you can see the actual difference between a normal and a tiny house. The amazing thing about the tiny house is that if you design it right, plumbing can be very easy to run. As your home is small, your plumbing system infrastructure must be very simple and less expensive.

Here, in the diagram, you can visualize how the plumbing system works. You can plan how to do plumbing for a new tiny house.  Water supply usually comes into the house either on-grid or off-grid water system. Then the line is divided into hot water and cold-water pipeline. Hot water can be generated using a traditional or tankless water heater. Both the cold and hot water lines are connected to the kitchen sink and bathroom shower to provide a water supply. The drain line comes from two connections. One is from under the shower, and another is from the sink. Most importantly, the connection pipes tou will be using must be robust and flexible. There are different material options you can find in the market. We will discuss it briefly later. 

Water resourcing setup in tiny house plumbing system:

If you plan to have a permanent water supply to your tiny house, you will need a grid-connected water system. This option is none other than just like your traditional house plumbing system. You will always have access to a water source. You will get water from municipal sources, which will be connected directly with your main system, and you can dispose of wastewater through a sewer system. This is only applicable if you only build a tiny immovable house.

If you build your tiny house on wheels, you will need an off-grid water system. An off-grid water plumbing system lets you take your tiny house traveling with you. If you can allocate yourself near a water source, it will be much easier and more beneficial to collect water. But there is no guarantee that you can always manage a water resource around you for your off-grid water system. So basically, you will need a water pump and water tanks as water resources to install an off-grid system.

Water pump and water tank categories:

So for a basic off-grid water plumbing system, you will require a water pump and water tanks for water resources. It is the best option for tiny house owners to have a water pump to invest water. It gets connected with water tanks and grid connections. It will give you regular water flow for your kitchen and bathroom use. Besides its benefit, it comes with a disadvantage like water pumps are noisy when used. But  Of course, considering its usefulness, you can ignore its downsides. 

For storing water, you will need three types of water tanks.

The freshwater tank is for holding freshwater for your kitchen and bathroom use. According to statistics, average people generally use 80 to 100 gallons of water per day. Filling the freshwater tank is very flexible. You can refill it from any campground or park. Besides, federal lands can be another option you can use. Many people use rainwater to fill the tank and use it as freshwater. 

The next is the gray water tank which contains wastewater. The wastewater comes from the kitchen sink, washing machine, and bathtub. It doesn’t have any kind of human waste. You should not release gray water to any kind of lake. Otherwise, water will get polluted. What you can do is release the water around trees and plants. They will use it as fertilizer. So it is very easy to drain out gray water from your tiny house. 

The last one is the black water tank which holds the sewage. It directly stores the wastewater coming from the toilet. You will need the black water tank to collect wastage and release it to the dump station. So, you can find it dirty, but if you choose the off-grid water system for your tiny home and don’t use a composting toilet, then there will be no other option for you.

As the tanks are very big, they require a lot of space. But don’t worry. There are plenty of ways to manage these tanks in your tiny house. 

Water heating system:

There are two ways to heat your tiny house water. One is traditional, and another is the tankless water heater.

In a traditional water heater, the tank water is heated at a specific temperature and allows you to enjoy a relaxing hot shower. Also, it is the most popular type of water heater system. It requires more space which is not preferable for tiny houses. The tankless water heater is the latest innovation specially designed for tiny houses. It runs on a gas or electric power supply, which is more effective than the traditional water heater system. Whether you choose off-grid or grid-connected water supply, a tankless water heater system is more sustainable and cheaper to maintain.   

Toilet options:

Tiny house toilet options are the most common topic for tiny house builders. It is a bigger issue when it comes to building a tiny house. There are many toilet options in the market that you can choose from, like Composting Toilets, Macerating Toilets, Cassette Toilets, Incinerating Toilets, and more. But the most popular is composting toilets. 

It is a very natural process and can be cleaned easily. It uses the natural decomposition process like sawdust and coconut husk to speed up the decomposition procedure and turn it into usable compost. There is another type of composting toilet called Nature’s head. It has urine and a solid separator. It is much effective and highly recommended. Composting toilets are very inexpensive and very easy to maintain. Many other toilet options are available in the market that can give a traditional flush toilet feeling. But they are costly and need professional plumbers to install.

Plumbing pipes:

It is essential to choose suitable pipes for the plumbing setup. When you go for building your tiny house, you will find different material pipes like Pex, Copper, and CPVC.

Copper pipes were used before for their extremely durable feature. But they are very expensive and leave a metallic flavor to the water. Pex and CPVC are the modern discovery in the plumbing system. Pex is known as Cross-Linked Polyethylene water lines. It has grown its popularity for super easy to work with features. It is comparatively inexpensive too. It can handle freezing temperatures. Pex enables quick connect fittings and ensures water-tight connections though out the system. The pex can be in different shapes, colors and lengths. It has created an outstanding output in the new plumbing system.

CPVC is also very work-friendly. It also comes with colors that make it easier to detect joints after dry fitting. Cutting CPVC pipes with a pipe cutter is like cutting butter with a knife. Even if you plumbed your system wrong, you could replace it with CPVC pipes because they are super cheap. So both pex and CPVC pipes are great to use.
