Apply Teflon tape evenly around the male thread of the fitting before screwing it onto the pipe. Tighten securely by hand, avoiding excessive force to prevent damage.

While not always required, a PVC-compatible sealant can be applied to the joints for added protection against leaks. Ensure it’s compatible with the pipe material.
What is the typical lifespan of McAlpine DWV fittings?
With proper installation and maintenance, McAlpine DWV fittings are designed to provide a long service life – typically 20-30 years for residential applications and longer in commercial settings. Refer to the manufacturer’s warranty details.
