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

Took 5 minutes to install.

These cheap plastic valves last about six months. They should sell them by the gross. Total garbage.

Why glacier doesnt supply parts for there products Ill never know. This was a snap to put in.

Works perfectly in the Glacier Bay toilets.

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!

Fit perfectly

works great

The valve failed within a month or two, letting water past the diaphragm even after the valve should be fully closed. This causes the toilet to run continuously, albeit at a lower volume vs fully open. Upon disassembly and inspection, the rod is not exerting enough force to push the diaphragm to seal. Its a poor design, the push rod is only connected to the diagram by friction. A simple mechanical stop via increase in diameter would fix this easily.

just what i needed

Works fine
