Frequently Asked Questions
• 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 THU489-A Toilet Inlet Pipe is a genuine TOTO replacement part designed for select concealed in-wall tank systems. It creates the flush-water connection between the carrier and the wall-hung toilet bowl, helping restore proper fit and reliable flushing when the original pipe is damaged, missing, or needs to be replaced.
This inlet pipe is compatible with TOTO WT172M, WT173M, WT173MA, WT174M, and WT175MA in-wall tank systems. The THU489-A includes the inlet pipe only and does not include the inlet gasket, outlet pipe, mounting hardware, or other carrier components. Confirm your existing tank model before ordering to ensure compatibility.
