Plumbing installations is a big part of any bathroom or kitchen renovation. Whether you’re doing it yourself or hiring a pro, knowing the steps will help it all go smoothly. From pipes to fixtures, bathroom and kitchen plumbing installations require planning and execution. Here are the 7 steps.
1. Plan
Before you start your bathroom and kitchen plumbing installations, planning is key. This stage involves working out the layout, fixture placement and making sure your plumbing system will service both rooms. For example, where will the sinks, showers and dishwashers go and how will the plumbing connect.
Planning Phase:
- Local Building Codes: Make sure you know the local plumbing codes and regulations as you’ll need to follow them throughout the installation.
- Water Supply and Drainage: Where will the water supply lines and drainage pipes run in the kitchen and bathroom. This will affect the efficiency of your plumbing system.
- Future Maintenance: Plan your layout so the plumbing components are accessible for future maintenance or repairs.
2. Water Supply Lines
Water supply lines are the backbone of any plumbing system. In this step you’ll install pipes that carry water to your bathroom and kitchen fixtures, sinks, faucets, toilets and showers. PEX or copper pipes are commonly used for water supply lines, each has its own benefits.
How to Install Water Supply Lines:
- Turn Off the Main Water Supply: Before you start, make sure the main water supply is turned off to avoid any accidental flooding.
- Run Pipes to Each Fixture: Measure and cut your pipes to the correct length, then install them to connect to each fixture in the bathroom and kitchen.
- Secure Pipes in Place: Use brackets or straps to secure the pipes to studs or joists so they don’t move.
3. Drainage Pipes
Bathroom and kitchen plumbing installations require a proper drainage system to carry wastewater away from your home. Drainage pipes are PVC and are responsible for removing used water from sinks, toilets, showers and dishwashers.
How to Install Drainage Pipes:
- Slope: Drainage pipes must be installed at a slight downward slope (usually 1/4 inch per foot) so gravity can help move the wastewater.
- Ventilation: Make sure your drainage system has a vent pipe so air can enter, to prevent clogs and maintain flow.
- Connect to the Sewer Line: Your drainage system will need to connect to the home’s main sewer or septic line.
4. Fixtures in the Bathroom and Kitchen
Now that your water supply and drainage lines are in place you can install the fixtures. This includes sinks, toilets, showers, tubs and dishwashers in the kitchen and bathroom. Each fixture has its own installation requirements but generally it involves connecting them to the supply and drainage pipes.
Common Fixture Installations:
- Kitchen Sink and Dishwasher: Connect the water supply lines and ensure drainage. In the kitchen you’ll also want to install a garbage disposal if needed.
- Bathroom Sink and Toilet: Attach the water supply lines to the faucet and toilet and connect the drainage system for proper waste removal.
5. Test the System
Before you close up walls or seal floors you need to test your plumbing system to make sure there are no leaks or malfunctions. Turn on the water supply and run each fixture to check for leaks, proper water pressure and drainage.
How to Test Properly:
- Check All Connections: Make sure all supply line connections are watertight and there’s no signs of leaks.
- Monitor Drainage: Run water through each fixture and make sure the wastewater flows smoothly through the drainage pipes without backing up.
6. Insulate the Pipes
To prevent pipes from freezing or losing heat insulating your water supply lines is a must in bathroom and kitchen plumbing installations. Insulation also reduces noise from water flow in the kitchen.
Benefits of Pipe Insulation:
- Energy Efficiency: Insulated pipes reduce heat loss so you have consistent water temperatures and lower energy bills.
- Freeze Protection: Insulation prevents pipes from freezing in cold weather, reducing the risk of bursts or leaks.
7. Final Touches and Inspection
The last step in your bathroom and kitchen plumbing installations is to add the final touches and do an inspection. Once you’re satisfied everything is working as it should you can close up any walls or floors that were opened during the installation process.
Final Notes:
- Seal Openings: Make sure any gaps around pipes are sealed to prevent leaks, drafts or pest entry.
- Professional Inspection: If you’re not sure about any part of the installation it’s a good idea to have a professional plumber inspect the system to make sure it’s up to code.
