This project is continued from How to Replace a Toilet Fill Valve – Part 3.

Install the Toilet Connector Hose

A new Brasscraft Speedi Plumb PLUS toilet connector hose reinforced with steel braids will replace the old plastic PVC hose. The Brasscraft hose is 9 inches in length with a 7/8 inch fill valve fitting and a 3/8 inch compression nut for the water supply valve. The Brasscraft hose is pre-assembled with the cone washer and ready to install.

The Brasscraft toilet connector hose has a large wing nut for hand tightening to the shank of the fill valve. It helps to hold the toilet connector hose to prevent it from twisting as you tighten the wing nut.

Install the Toilet Valve Refill Tube

Slip the refill tube over the fill valve nipple while holding the fill valve to avoid bending/stressing valve body. The purpose of the refill tube is to fill the toilet bowl with water after flushing:

Remove the old refill tube holder from the overflow pipe by sliding it off the end of the pipe:
