The MOUNTAIN PLUMBING MT435X/SG is a 12-inch toilet supply line finished in satin gold. It connects the shut-off valve to the fill valve on the toilet tank, providing a secure water supply link in residential bathroom installations. The satin gold finish coordinates with matching trim and fixture hardware. This supply line is a straightforward replacement or new-installation component handled by licensed plumbers or experienced DIYers completing a toilet installation or fixture upgrade.
This supply line is suited for standard residential toilet installations where a 12-inch reach from the wall stop to the toilet tank fill valve is required. It is a practical choice for bathroom remodels or fixture replacements where the satin gold finish is needed to match existing hardware and trim. Install location is typically at floor-level or near-floor wall supply stops feeding a standard two-piece or one-piece toilet.
Designed as an OEM-style replacement or upgrade supply line for standard residential toilet installations requiring a 12-inch supply connection.
Installation is performed by a licensed plumber or qualified DIYer. Always shut off the water supply at the angle stop or main shut-off and flush the toilet to relieve pressure before disconnecting the existing supply line. Hand-tighten connections first, then snug with pliers — do not overtighten, as this can crack the fill valve shank or damage fittings. Verify there are no leaks at both connection points after restoring water supply.
