Steps to Connect the Main Water Line to House

Now that you have planned and gathered all the necessary tools and materials, you can follow these steps to connect the main water line to your house:

The first step is to dig a trench from the main water line to the location where you want to connect it to your house. The trench should be at least 18 inches deep and long enough to reach your house. It is important to ensure that the trench is straight and not curved.

Step 2: Install the Water Meter

Step 4: Connect the Water Line to the Shutoff Valve

Once the shutoff valve is installed, you need to connect the water line to the shutoff valve using compression fittings. Compression fittings are easy to install and do not require any special tools. You need to follow the manufacturer’s instructions to install the compression fittings properly.

Step 5: Connect the Water Line to the House

After connecting the water line to the shutoff valve, you need to connect it to your house. You need to use PVC pipe and PVC cement to connect the water line to your house. You need to follow the manufacturer’s instructions to install the PVC pipe and PVC cement properly.

Step 6: Test the Water Supply

Once you have connected the water line to your house, you need to test the water supply. You can turn on the shutoff valve and check if there is any leakage or low water pressure in your house. If there is any issue, you need to fix it before using the water supply.
