Sharkbite 24636LF Anti-siphon Sillcock

Product Description

The SHARKBITE 24636LF is an anti-siphon sillcock designed for outdoor water supply applications in residential and light commercial plumbing systems. Anti-siphon sillcocks prevent backflow by stopping contaminated water from being drawn back into the potable water supply when a hose or downstream device creates negative pressure. The lead-free construction of the 24636LF meets current federal and state requirements for fixtures used in potable water systems. This fitting is installed by licensed plumbers or experienced tradespeople as part of exterior wall rough-in or replacement service work.

The 24636LF is suited for through-wall installation on residential homes, light commercial buildings, and similar structures where a code-compliant, anti-siphon hose bib is required. It is sold individually and intended for installations where backflow prevention at the point of use is required by local plumbing code. The lead-free designation makes it appropriate for new construction and retrofit projects subject to lead-free fixture mandates.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) where adopted. Shut off the main water supply and depressurize the line before beginning work. Ensure proper through-wall support and slope toward the exterior to allow drainage and prevent freeze damage in cold climates. Do not overtighten threaded connections; use appropriate thread sealant or tape rated for potable water.
