What is the distance of vent from trap seal?

The distance of a vent from a trap seal typically depends on local Plumbing codes and regulations. Generally, the vent should be installed within a certain distance from the trap to ensure proper drainage and prevent siphoning of the trap seal. This distance is often around 4 to 6 feet for most applications, but it's essential to consult specific plumbing codes for precise requirements. Proper venting is crucial to maintain appropriate air pressure and prevent odor issues in plumbing systems.
