Should a gas regulator include a drip tee and union before its location?

A gas regulator should include a drip tee and union before its location because these components serve important functions in a gas piping system. The drip tee allows for the collection and removal of any condensation or liquids that may accumulate in the gas line, which is vital for ensuring that only vaporized gas reaches the regulator and downstream appliances. This helps to prevent damage to the regulator and other equipment, as well as ensuring optimal performance and safety.

Incorporating a union before the regulator facilitates easy disconnection for maintenance or replacement of the regulator without needing to cut the piping. It allows for flexibility in the system, making it easier to service or upgrade components as necessary.

Therefore, including both a drip tee and a union before the gas regulator is a best practice for maintaining reliability, safety, and ease of maintenance in gas piping systems.
