If you learn how to run plumbing to a detached garage or shed, you can create a world of possibilities! A utility sink in either space makes it easier to clean lawn care equipment and paint brushes. Renovating either space with a bathroom and kitchen can also allow you to create an additional dwelling unit. Where legally allowed, you can then earn an income or have a family member move in!
How to run plumbing to a detached garage or shed:
Obviously, this is just a quick rundown of what’s needed to run plumbing to a detached garage or other outbuilding. Also, a professional plumbing contractor can make quick work of this project and ensure it passes inspection. However, if you want to try at least some steps yourself, check them out in more detail.
Running plumbing to a detached garage or shed starts with proper planning for bathroom plumbing! Don’t just run to the hardware store, buy some pips, and start digging. Also, remember that you need to obtain the necessary permits and schedule inspections. Here's a general overview of the process:
Contact your local building department to inquire about necessary permits and regulations. Remember that you’ll need to obtain the required permits before starting any work to ensure compliance with local codes. This process can sometimes take weeks, so be sure you plan accordingly.
Purchase the appropriate plumbing pipes (PVC, PEX, or copper), fittings, valves, and fixtures. Don't forget tools like pipe cutters, wrenches, soldering equipment (if using copper), and pipe glue (if using PVC). Also, you’ll probably want to buy more than you need, in case of mistakes when cutting. You also don’t want to be in the middle of a project and find out that the store is out of stock on certain items!
Dig a trench from the main water supply and sewage lines to the location of the detached garage or shed. Ensure the trench is deep enough to protect the pipes from freezing and damage. Check local frost line depths.
Lay conduit for protecting electrical lines, if necessary. Your permitting office will note these regulations. If you’re not sure they require conduit, consider installing it anyway. This means extra protection for those lines and wires.
To lay pipes, install the main water supply line from your main water source to the garage or shed. Use the appropriate pipe type for your needs (PEX is often easier for DIY installations). Install drain pipes for sinks, toilets, or showers, ensuring proper slope for drainage. Connect the pipes using appropriate fittings, glue (for PVC), and clamps (for PEX).
Install fixtures such as sinks, toilets, showers, or utility sinks according to the manufacturer's instructions. Connect the fixtures to the water supply and drain lines.
Ensure proper ventilation for the plumbing system to prevent airlock and sewer gas buildup. Install vent pipes that extend above the roofline.
After installing the plumbing system, conduct pressure testing to ensure there are no leaks. Close off all fixtures and pressurize the system to check for any drops in pressure.
Once the plumbing system passes pressure testing, backfill the trench with soil, ensuring no sharp objects can damage the pipes. If you've installed electrical conduit, make sure it's properly protected and covered.
If connecting to a municipal sewer system, consult with the local utility department for proper procedures and obtain necessary permits. Install the appropriate connections and pipes to connect to the sewer system.
Contact the local building department for required inspections at various stages of the plumbing installation. Don’t overlook this step as an inspection releases your permits. Without a proper inspection, you might face fines from the city. Also, it’s difficult to sell a home without inspections for DIY projects.
Once you’ve completed all these steps, you can add finishing touches to your outbuilding. This includes any interior work, such as walling, flooring, and fixture installation. Also, don’t forget to maintain the plumbing as needed over the years. This includes checking for leaks and insulating the pipes against freezing.
