R&T A1320 Toilet Fill Valve – Universal Replacement Kit | Quiet, Fast Fill, Adjustable, DIY Install

Upgrade your toilet's performance with the R&T A1320

The R&T A1320 toilet fill valve offers a compact, dependable upgrade for many American Standard and other common tank designs. It targets common bathroom annoyances—slow filling, noisy operation, leaks, and running toilets—by delivering a quiet, steady fill that supports overall tank performance without drama.

Built with safety and reliability in mind, the valve uses BPA-free ABS plastic and an anti-siphon design. This combination helps keep your water clean and reduces backflow concerns, while the valve delivers the correct amount of water to the tank to support consistent operation and potential water savings.

Installing the A1320 is straightforward. A quick locking nut allows tool-free mounting, and you can easily adjust the float height after installation to set the ideal water level for your tank. The height range from 9.2 inches to 13 inches fits many common models, reducing guesswork during a DIY fix.
