Cat Faucet Angle Adapter install

Here’s how I installed the Cat Faucet Angle Adapter on one of my sinks. As you review the images note that in this case the sink has a flexible line rather than a stiff copper tube. Because the angle adapter needs to be inserted in-line you need a bit of flexibility to move the existing line. You could probably do this with a faucet with a copper tube, but the stiffness of the copper tubing will make it more difficult.

Here you see the sink before I installed the Cat Faucet Angle Adapter. Note that this is flexible tubing from from the sink, not stiff copper pipe. Before you proceed, turn off the water and the faucet right here in at the faucet attachment. Turn the faucet on to make sure you really do have the water off!

Here we’ve disconnected the sink from the cold water supply. Note a few drips do come out of the tubing, but that should be it. Careful taking this off if the fitting is tight. You don’t want to snap the water supply tubing coming out of the wall.

Here we’ve initially installed the 3/8″ connector on to the 3/8″ compression fitting on the sink’s water supply. Hand tighten this only!!.

Here we’ve reconnected the water to the sink. Carefully thread the compression fitting back on. the Angle Adapter is plastic so easy to strip. Make sure the threads are aligned proper before you take a wrench to this to tighten the fitting. Again do not over tighten! we don’t want to strip the plastic threads.

Once the sink cold water line is reattached to the angle adapter, push in the Cat Faucet inlet tube into the 1/4″ push in adapter. Make sure you push this in all the way. Might be hard to reach under the sink, but make sure it goes in all the way.

Now turn on the sink’s cold water supply. Any leaks? Open the Angle Adapter valve slightly. As you can see in the picture, only a little bit open will get you sufficient flow out of the Cat Faucet. Again check for leaks. I suggest wiping everything dry, then placing a paper towel under the connection. Come back in a couple of hours to see if it’s dripping at all. Any drips? make sure the tubing is pushed in all the way. Make sure the 3/8″ fittings are snugged up. Make sure the cold water valve itself isn’t leaking. Sometimes these old valves that hardly ever get opened or closed will leak after being closed/re-opened.
