Sometimes we need to replace Qest shutoffs. Normally after there has been a big flood in a home, and the insurance company wants the rest of them replaced. I have never been a big fan of plastic shutoffs in homes.
They are sometimes called Quest, but that's just one too many letters.
Here is a Qest shutoff with their own supply line.
After shutting off water to the home, I remove the shutoff from the backing nut. There is a cone washer backed by a metal keeper washer. I sometimes can hit that with a screwdriver and break the ring, but sometimes I need to cut two slots in the nut, insert a flat blade and twist, to pop the section of plastic out.
Now I have more room to access the backing metal washer.
I have the washers in the wrong order here. The metal washer hides behind the cone washer.
I trimmed just a bit off the copper pipe from the wall and used a new 1/4 turn shutoff and new braided supply line.
