In a washbasin system, the push-button drain and P-trap are two important components that help ensure fast drainage, no leaks, no odors, and a high level of aesthetics. TOTO products such as T6JV6, T6JV2N, and the TVLF401 TVLF402 TVLF403 TVLF404 TVLF405 drain pipe series are popular choices for high-end projects, hotels, townhouses, and apartments.
