This project is continued from Part 2.
This is the 1/2 inch cold water copper pipe stub protruding from the bathroom floor after removing the old stop valve. The oxidation and build-up of minerals must be cleaned before the new 1/4 stop valve is installed.
Toilet Water Stop Valve Installation: 1/2 inch Copper Pipe Stub
The Oatey 4-in-1 brush does a great job of cleaning the copper pipe stub. Just wiggle the brush back and forth on the pipe.

Toilet Water Stop Valve Installation
The new Brasscraft 1/4 Stop Valve, compression nut and brass sleeve are ready for installation on the polished copper pipe stub. Notice the deep pocket on the bottom of the stop valve to receive the pipe stub.
1/4 Toilet Water Stop Valve Installation: New Valve and Clean Pipe Stub
Slide the compression nut over the pipe stub with the threads facing the end of the pipe, then slip on the brass compression ring as shown:

Set the stop valve body on the end of the pipe stub and press it down until it bottoms out in the valve body. Turn the valve body until the valve handle is in the position you prefer, I like it parallel to the baseboard.

Spin the compression nut on the stop valve body with your fingers, then place a wrench on the valve body to hold it steady and tighten the nut with a second wrench. Tighten the nut a 1/2 turn after you feel it seat or bite against the brass sleeve. Do not over tighten the nut to avoid cracking the valve body or nut. You can always tighten the nut slightly if there’s a leak when the water is turned on.

The new water stop valve is installed on the 1/2 copper pipe stub. Almost done!
Brasscraft® 1/4 Stop Valve Installation: Compression Nut Tighten
I use the steel braided Brasscraft® Speedi Plumb® PLUS Toilet Connector hose which has a 3/8 inch compression nut and o-ring built into the hose. Unscrew the 3/8 inch compression nut from the new stop valve. Set the nut and brass sleeve aside. (Note: You may need these if your toilet connector hose is different!)

Attach the toilet connector hose to the stop valve and tighten with a wrench. Do not over tighten.

View of the new 1/4 turn toilet water stop valve and connector hose. I’m now ready to turn on the water and check for leaks.
1/4 Turn Toilet Water Stop Valve Installation Complete
Turn on the Water and Check for Leaks
Turn on the water at the water meter and close the faucets that were opened after air in the pipes stops sputtering out.
Turn on the water stop valve to refill the toilet tank. Check the valve connections for leaks. Tighten the compression nuts a 1/4 turn if you find a leak.
