After testing and researching, we found that the process of brazing the tee caused inconsistency with the crimping process. We have begun using a forged tee which eliminates the inconsistencies in the process and solves the leaking problem. You will need a new hose assembly (part number RP34352).
It is extremely rare for a lavatory faucet to develop a leak under the counter. Typically, leaks under the counter occur upon installation due to one of two factors.
With Quick-Snap® connections - Newer Delta widespread faucets feature Quick-Snap® installation. If you have Quick-Snap® connections and experience leaking at the connection points, Quick-Snap may not have been properly installed. Follow these steps to check the Quick-Snap connections:
Here are some tools you may need:
With normal wear, the faucet’s seats and springs become worn, which may result in a leak from the spout. To stop the leak, simply replace the seats and springs by following these steps:
Here are some tools you may need:
Your Delta® faucet is designed for leak-free performance. Through normal use, and depending on the water conditions in your area, seats and springs experience wear and may need to be replaced occasionally. It is also possible that there is sediment or debris in your lavatory faucet. If your faucet drips from the spout, follow these simple steps:
First attempt to flush the debris from the system:
Look under the sink to be sure the strap assembly that operates the stopper is properly adjusted and that the nut holding the horizontal rod in the drain assembly is secure. Be sure the stopper is properly adjusted.
Note: The cap on the stopper is not designed to be flush with the flange. A seal is created by the weight of the water, which pushes the rubber seal under the stopper against the flange in the sink.
If this is a non-pressure balance tub or shower:
On a single-handle tub or shower, you need to tighten the adjusting ring or replace the cam and packing.
Tighten the adjusting ring until no water leaks around the stem when the faucet is in the full-on hot and cold mixed position and pressure is exerted down on the handle.
It is normal for a small (pencil thin) stream of water to continue to flow from the tub spout when the shower is in operation. If the amount of water flow is excessive, then this indicates a problem with the diverter located in the tub spout. This cannot be repaired, and the spout must be replaced. Remove the tub spout and replace it with a Genuine Delta tub spout.
First, we need to find out if the hot or cold valve is causing the leak. Let's begin by troubleshooting with the hot valve:
You need a new cartridge assembly (part number RP19804). You may notice that the new one will be blue and white, while yours may be white. This is just a change in manufacturing which will not affect your ability to use it.
