• What if my order arrives damaged?
While we take great care in the packaging and handling of orders, we ask that customers inspect all shipments within 48 hours of delivery, and in the rare event that your order arrives damaged, please send us an email with a photo showing the damages (so we can file a claim with the carrier), and let us know whether you prefer a free replacement or a refund.
• Why do you ask for phone numbers during checkout?
Some shipping carriers, especially those handling freight, require a phone number to coordinate your delivery. We respect your privacy and guarantee that any information you provide will never be shared with third parties, except for shipping purposes.
The TOTO THU420#CP Push Button is a genuine TOTO replacement component designed for select Rowan dual-flush toilets. Installed in the opening on top of the toilet tank lid, the chrome-plated button operates the full and reduced flush settings, helping restore proper flushing control when the original button becomes damaged, worn, loose, or difficult to operate.
The THU420#CP is compatible with the TOTO ST405M tank used on CST405MF round-front and CST406MF elongated Rowan toilets with a 1.6 and 1.0 GPF Dual-Max flushing system. This replacement includes the push button and mounting nut only and does not include the tank lid, button label, flush tower, fill valve, or other internal tank components. Confirm the complete toilet or tank model before ordering to ensure proper compatibility.
