Here is how to tie into an existing PVC plumbing pipe.
Before you start, shut off the main water supply and open a nearby tap to drain any water left in the pipe. Make sure the existing pipe is completely dry before making the connection.
Choose the exact section where you want to connect the new pipe.
Use a marker to indicate where you need to cut the existing PVC pipe.
Check the measurements carefully so the new fitting sits properly.
Use a PVC pipe cutter or a fine-tooth hacksaw to make clean, straight cuts. Remove any burrs or rough edges with sandpaper or a deburring tool.
A PVC tee fitting usually works well when you want to create a new branch from an existing pipe.
Select a tee that matches the pipe diameter.
If you cannot move the existing pipe enough to fit the tee, use a repair coupling or another suitable fitting designed for this type of connection.
Connect the tee and new pipe without glue to check the alignment. This step helps you identify measurement or positioning problems before you make the connection permanent.
Clean the pipe and fitting surfaces.
Apply PVC primer if required for your pipe and cement system, followed by PVC cement.
Push the fitting onto the pipe while giving it a slight twist. Hold it in place for a few seconds so it does not move.
Attach the new PVC pipe to the branch of the tee using the same preparation and cementing process. Allow the joint to cure for the time recommended on the cement label.
Turn the water supply back on slowly and check every joint for leaks. If you notice any leakage, shut off the water and fix the joint before using the plumbing line normally.
I hope you now know how to tie into an existing PVC plumbing pipe.
