What you need:
1/4” OD metal tube
Stiff spring that has a loose fit over the rod
1/2"OD, 3/8"ID vinyl tubing
3/4" PVC tee
3/4" to 1/2" reducer bushing (x 2)
1/2" PVC threaded plug
1/2" OD, 1/4" ID rubber o-ring
1/2" Angled faucet gasket (Actual OD 3/4")
Take one reducer bushing and goop the hose washer on the 3/4" end. Make sure the washer is perfectly round. Goop the bushing into one of the cross-sections of the PVC tee.
Take the threaded plug and hacksaw off the lip section (the section that you hold onto when you screw it in.) Drill a 1/4" hole into the exact center of the plug and work the drill bit in the hole to enlarge it. You want the hole big enough for the tube to slide through without touching. Drop the rubber o-ring into the plug and make sure it aligns with the drilled hole. Cut a section of vinyl tubing to fit completely in the plug. Goop it into the plug, making sure it presses against the o-ring securely.
Take your threaded plug setup and goop it into the other reducer bushing making sure the hole in the plug is facing out.
Take your faucet gasket and drill a 1/4" hole into it. Use adjustable pliers to hold the gasket while you drill so you don’t hurt yourself if the drill skips. Goop the gasket onto the end of the tube with the angled side out. Put goop inside the gasket end of the tube to make it airtight.
Temporarily put the tube through the o-ring setup and put the setup into the other end of the PVC tee. Measure how long the spring will need to be to securely hold the gasket against the washer. Cut the spring to that size, plus a little for tension. Remove the o-ring setup from the PVC tee, and remove the tube from the o-ring setup.
Wait for everything to dry 24 hours.
Then slide the spring over the tube and replace it in the o-ring setup. Goop the o-ring setup in the PVC tee, and let it dry 24 hours. Spray the both sides with silicon spray, and you are done! To open the valve, pull the tube, and to close it, let go!
I know this sounds confusing, but this drawing should help out. I intend to take pictures of the process before I submit this to Cxwq.
Edit: The reducing bushing on the right side is to allow direct feed to a 1/2" PVC barrel. You could swap that bushing for regular 3/4" PVC if you want.
