How to Replace a Toilet Fill Valve: Install the reinforced toilet connector hose and connect the valve refill tube. 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:

Install the angle adapter on the overflow pipe as shown and measure where to cut the refill tube at the nipple of the angle adapter. I just pinch and hold it at the right length, then cut the tube with scissors:

Help I can’t unscrew the winged plastic nut I’ve sprayed ed40 but I can’t turn it still any suggestions
Try using channel locks for better leverage on the stuck wing nut. You can find them at just about any hardware or home improvement store.
Howdy Bob Jackson, I’ve got a channel lock except I’m in a very confined space to work with so there’s just not enough room to work with it. I just can’t get that dang winged plastic nut off! Any suggestions?
Howdy! I know my comment got deleted yesterday, but I figured out my issue of not being able to remove my wing nut and thought it might help others if I shared. So, my toilet is in a very tight spot in a small bathroom, so I couldn’t get under it to really see anything. The solution ended up being that the wing nut unscrews clockwise instead of counter-clockwise like most other stuff. Is that typical for a toilet valve?
Hi Justin,
Your comment didn’t get deleted, it was in the moderation queue pending approval.
Every toilet connector hose and fill valve nipple that I’ve seen has right hand threads which follows the “righty tighty – lefty loosey” saying, where turning the nut clockwise screws it on. The fill valve on my toilet clearly has right-hand threads as shown in this photo.
Glad you got it fixed.
Bob
