K1193 Instructions - M76
K1193 Deck Union - M76
Things You May Need: 1-1/2" Basin wrench, adjustable wrench, arc-joint pliers, #2 Phillips screwdriver, bucket, towels, safety goggles, flashlight and a Helper to hold things in place from above while you tighten from below.
Plug your sink drain(s) so that no small parts will go down the drain if you drop them.
- Remove the screws from the faucet handles.
- Remove the handles.
- Remove the knurled cover retaining rings.
- Remove the cover and face plate.
- Remove the hose retainer and hose from the cover.
- Place the deck union flanges onto the long end of the deck unions. This K1193 differs from the K1191 in that the faucet can be raised higher above the sink if the deck union flanges are not screwed all the way onto the deck unions.
- Place the black deck union seals onto the long end of the deck unions and slide them up tight to the deck union flanges.
- Place the O-rings in the grooves in the face of the short end of the deck unions. Applying a small amount of silicone plumbers grease or vaseline to the O-rings will help hold them in place. The O-rings MUST be used for proper installation. Failure to use the O-rings WILL cause the faucet to leak.
- Loosely attach the deck union assemblies to the valve seats by screwing the union coupling nuts to the short end of the deck union assemblies. Do NOT tighten at this time..
- Position the faucet in the holes on the sink/countertop.
It is convenient to have a helper apply downward pressure on the faucet to hold it in place until completion of the next step. Place a couple towels on the bottom of the cabinet to cushion your back. Wear safety goggles.
- Screw a deck union lock nuts onto the deck unions and tighten securely while your helper holds the faucet in position.
- Firmly tighten the union coupling nuts. These are not tapered pipe threads and should not be over-tightened. The watertight seal is made by the O-rings.
- Reinstall the hose clip and hose onto the cover.
- Reinstall the cover and face plate.
- Reinstall the knurled cover retaining rings.
- Slightly engage the spline on the handle with the spline on the hot valve stem and rotate clockwise until the valve is just snug (counter-clockwise for cold side).
- Remove the handle.
- Position the handle in front of the stem at the 7 o'clock position (5 o'clock for the cold side).
- Reinstall the handle by fully engaging the spline.
- Reinstall the screw.
- Turn the handle fully clockwise to close the valve (counter-clocksise for the cold side).
- Put the end of the hot supply line into a bucket. Gently open the shut-off valve and allow water to flow until foreign matter no longer comes out. Close the shut-off valve.
- Repeat the procedure for the cold supply line.
Important: for next 2 steps. The deck unions are ½” straight iron pipe. They are NOT tapered pipe threads. The watertight seal is made by the gasket on the supply line. Do NOT over-tighten the water supply lines.
- Attach the hot water supply line to the left deck union body. Tighten only enough to seat the gasket in the supply line.
- Attach the cold water supply line to the right deck union body. Tighten only enough to seat the gasket in the supply line.
- Unscrew the aerator assembly from the end of the spout (counter-clockwise). Be certain to remove the black seal along with the aerator. It will sometimes stick to the spout rather than come off with the aerator.
- Gently open the hot water shut-off valve. Examine the water supply line and fittings to make sure there are no leaks. If there is a leak, tighten the fitting enough to stop the leak.
- Repeat for the cold water side.
- Slowly open the faucet valve handles. It is not unusual for air or air/water mixed to come out until the water lines fully fill with water. Allow the water to run until the air is out of the lines and foreign matter has flushed from the lines. Close the faucet handles.
- Check again for leaks. When all is well, re-attach the aerator assembly.
