Why do sprinklers use PVC for their pipes?

Many sprinkler systems use PVC pipes because of the material’s low cost and durability. PVC is resistant to corrosion and rust, and can withstand the pressure typically required in sprinkler systems without cracking. Similarly, you can expect your PVC tee fittings to last for years and years.

How do I install a PVC T-joint?

Start by cutting your PVC pipe to the exact length you’ll need it to be before insertion. Once it’s cleaned, apply a layer of PVC primer and a layer of adhesive cement to both the tee fitting and the pipe. Next, fit the pipes into the PVC T-joint and hold for a few seconds to ensure they set properly. Once the cement is cured, try running water through the system to see if it works.

What size T-joint should I use?

If you've already begun installing PVC pipes, choose a T-joint that matches their diameter. For example, you can order a 1-inch T-joint for 1-inch pipes. If your setup uses pipes of different diameters, you can use a reducing T-joint to make the connection.
