Kohler GP1138930 Universal Fill Valve for Most Toilets

lasted 6 weeks

The connector (7/8 ballcock) is special and not listed in the documentation. In Singapore this is not common and I had to order an special braided hose with the correct connector. But the fill valve is well built, easy to adjust the fill levels from the top knob.

The Kohler Silent Fill Toilet Valve Kit is a reliable replacement part that made fixing my toilet much easier. It’s designed to replace an old or worn‑out fill valve on Kohler toilets, and the “silent fill” feature noticeably reduces the usual rumbling or loud refill noise after flushing. Installation was straightforward — I followed the instructions, and it fit well without any complicated plumbing tools. The height is adjustable so it can match the tank’s water level properly, and the adjustment helped me get the right fill rate easily. As an OEM (original equipment manufacturer) part, it feels solid and durable. Most users report that it works quietly and reliably after installation, though there are occasional reports of adjustment being a little tricky at first. Bottom line: If your toilet is noisy, runs constantly, or isn’t filling right, this silent fill valve kit is a practical and affordable way to restore smooth, quiet performance. Great value for a basic but essential toilet repair part.
