A loop vent is a type of plumbing vent that is used to regulate air pressure in a kitchen sink's drain system. It is a simple and effective solution for preventing traps from becoming dry and stopping sewer gas from entering the home. Unlike traditional vents that require a direct connection to the roof, a loop vent can be installed horizontally and does not require any additional penetration through the roof.What is a Loop Vent for a Kitchen Sink?
A loop vent works by allowing air to flow freely through the drain system, preventing negative pressure from building up in the pipes. This is important because negative pressure can cause traps to become dry, which can lead to foul odors and even dangerous gases entering the home. The loop vent is typically installed underneath the kitchen sink and is connected to the drain pipe. As water flows down the drain, air is pulled in through the loop vent to equalize the pressure and keep the traps full of water.How Does a Loop Vent Work?
