Only the 2003 and newer Rialtas finally incorporated the tall head water faucet over the galley sink.  Previously owners had to struggle to wash pots and pans in this small sink with a water faucet whose outlet was low, almost level with the top of the sink.  That meant that large plates and pans could not be fully inserted under the stream of water without constantly rotating the item being cleaned.  And even then the water stream would only hit the outermost portions of the item.  The solution for those owners was to retrofit a newer modern faucet with the long extended neck and whose outlet was significantly higher than before.

Installation of this item is quite simple. PDF (52KB)  The hose connections under the sink utilize all plastic fittings and usually are nothing more than finger tight.  Once those hoses are disconnected, then the mounting bolts for the old faucet are removed and the new faucet takes the place of the old one.  All of the mounting dimensions and hardware are a plumbing standard so you can choose from a multitude of types and styles.  Expect to pay anywhere from $25 to $100 depending upon just how elaborate your tastes may run.

Here are pictures of two different styles:

Sink Faucet Replacement

Make it easier to wash hands, fill pots, and add a faucet water filter, by replacing the sink faucet with an extended faucet.



  • All prices are pre tax.

  • The new faucet is the only part for this modification.

  • Be sure to purchase a faucet with a spout that delivers the water at least 1-2 inches further away from the base, and preferably higher too, compared to the original equipment.  Not all "bar" faucets deliver water further out, just higher, so be sure to measure the extension length, from the centerline of the faucet, before you buy.

    Peerless Two Handle Lavatory Faucet Item #: 100484 Model: P99696, a bathroom sink faucet with a 2" longer and 3" higher spout delivery point (Bob Lutz) $48.00
    “Bar” faucet $25

    For QD you will need a Phillips screwdriver to remove the grill at the rear of the sink.  You may also want to use pliers to work with the plumbing fittings.


    NOTE #1: In additions to the following instructions, be sure to follow the instructions that come with the new faucet.

    NOTE #2: Instructions for Rialta HD and FD models are the same.  For QD models, first remove the vent on the back side of the galley sink for easy and visual access to the faucet.  Replace when finished installing the new faucet.

    1. Turn off the water pump and open the faucet, draining any water and relieving system pressure.

    2. Reach under the sink and "find" the cold water hose.  Twist by hand counterclockwise to loosen, and then disconnect the hose from the faucet fitting.  Leave the hose "standing up" to minimize any water dripping behind the sink, although a little water leakage will just evaporate away after a while, so don't worry.

    3. Now, find the hot water hose and do the same, leaving it upright.  I propped mine against the sink drain plumbing to keep it upright.

    4. Now, "find" the plastic nuts on the two faucet threads and loosen them.  The faucet should then be loose to the counter top.  Unscrew these completely and the faucet will lift out.

    5. Discard the old faucet and rubber/plastic seal piece.

    6. Wipe down and clean the area.

    7. Slip the rubber/plastic seal in place on the new faucet and set the new faucet in place, with the two threaded connections inserted through the two countertop holes.

    8. Use the new plastic or metal nuts to tighten the faucet in place from below.

    9. Reattach and hand tighten the hot and cold water plastic "pipes."

    10. Proof test your work by turning on the water pump and feeling for any water leakage.

    11. Open the faucet, both hot and cold and blow out the air until a smooth stream of water flows.
