Slide the valve completely onto the
bottom section of the tubing. Then
move it up to mate with the top section
and tighten the compression nuts.
If you’re installing an icemaker or a
reverse osmosis filtration system,
forget about using a traditional
saddle tee valve. They clog and
leak, and they’re almost impossible
to shut off completely after several
years of use.
Instead, install a sweat or compression tee with a 1/4-in. shutoff valve. Tees and shutoffs are available for copper, PEX, steel or CPVC, some with integral shutoffs like the unit shown here, which comes with compression fittings and a ball valve (available from Sioux Chief )
Shut off the water and cut the
copper tubing. Assemble
the compression nuts and ferrules
on the tee. Angle the tubing out to
install the unit. You can also install a standard tee fitting with a separate shutoff valve. Then connect the icemaker or filter. Make an access panel if you enclose the wall.
