Fluidmaster 703AP4 Specialty Toilet Fill Valve for Glacier Bay and Niagara Conservation Flapperless Toilets

I was unable to find one for my model number. This one was the closest to mine in appearance, as I had purchased an older home. It worked out perfectly and I was very pleased.

The quickest and easiest I’ve ever changed.

It works

The box is marked 703A, and the part number on the valve itself is 703A5B (this may be a sub-part number for the canister looking thing), but its identical to valve in my toilet. Changed in less than 5 minutes. Works great!

Fits perfect. Easiest fill valve replacement I ever did. CRITICAL POINT! There is a tiny white flow restrictor inside the old valve. The restrictor is smaller than a pencil eraser and is very easy to lose. Be sure to put this into the new valve as shown in the diagram. Other than that, an easy 5 minute job.

The perfect replacement part

Did exactly as it was suppose to.

It saved me from hiring a Plummer.

Worked perfectly
