Tools and Materials Checklist

Before starting, gather the following items. Having everything ready prevents mid-project trips to the hardware store.

Step-by-Step Installation Guide

Step 1: Shut Off Water Supply

Locate the shut-off valves under the sink. Turn both hot and cold valves clockwise until fully closed. Open the existing faucet to release residual water pressure and drain remaining water into a bucket.

Step 2: Remove the Old Faucet

Disconnect the supply lines from the shut-off valves using an adjustable wrench. If nuts are seized, apply penetrating oil and wait five minutes. Then, loosen the mounting nut securing the old faucet to the sink deck—a basin wrench works best for tight spaces. Lift the old unit out and clean the sink surface thoroughly with a degreaser.

Step 3: Prepare the Mounting Area

Your sink must have a single 1.375-inch (35mm) diameter hole. If there are extra holes, use a deck plate (not included) to cover them. Dry-fit the rubber gasket and metal washer onto the Xinbangye Single Hole Pull-Out Kitchen Faucet with Digital Display base to ensure proper alignment.

Step 4: Install the New Faucet Body

Feed the supply lines and digital display sensor cable down through the mounting hole. From under the sink, slide the mounting bracket over the threaded studs. Hand-tighten the locking nuts, then give them another half-turn with a wrench—do not over-tighten, as this can warp the gasket. Ensure the faucet is perfectly centered before final tightening.

Step 5: Connect Water Supply Lines

Attach the hot and cold supply lines from the Single Hole Pull-Out Kitchen Faucet with Digital Display to the corresponding shut-off valves. Wrap plumber’s tape clockwise around each valve thread (2–3 wraps) to create a watertight seal. Tighten connections firmly with a wrench, but avoid stripping the threads.

Step 6: Install the Digital Display Battery Pack

The Xinbangye model features a battery-powered digital display located on the faucet neck. Open the battery compartment (usually at the base or under the spout), insert 4 AA batteries (alkaline recommended), and close the cover. The display should flash briefly, indicating power is active. Some models include a USB-C backup port—consult your manual.

Step 7: Secure the Pull-Out Hose and Weight

Connect the pull-out spray head hose to the faucet body under the sink. Slide the counterweight onto the hose about 6 inches from the connection point. Adjust the weight’s position so the hose retracts smoothly but without excessive tension. Test the retraction 3–4 times before finalizing.

Step 8: Test for Leaks and Calibrate Temperature

Turn the shut-off valves back on slowly. Check all supply line connections for drips—tighten any that weep. Turn the faucet handle to the middle position and run water for 30 seconds. The digital display should show real-time temperature (in °F or °C). If the reading seems off, consult the Xinbangye manual for calibration mode (usually holding the display button for 5 seconds).

Pro Tips for a Smooth Installation

• Use a flashlight and mirror to inspect under-sink connections before tightening.

• Apply a small amount of silicone grease to the pull-out hose to reduce friction.

• If the digital display does not light up, check battery polarity orientation.

• For granite or solid-surface sinks, use a diamond-grit hole saw if drilling is required (rare for this single-hole design).

Common Mistakes to Avoid

FAQ – Single Hole Pull-Out Kitchen Faucet with Digital Display

Q: Does the digital display require a constant power connection, or does it work solely on batteries?

A: The Single Hole Pull-Out Kitchen Faucet with Digital Display from Xinbangye operates on 4 AA batteries, which typically last 12–18 months with average daily use (about 30 cycles per day). The display only activates when water flows, conserving power. A low-battery indicator (flashing red icon) appears on the screen about two weeks before depletion. For continuous operation, some models feature a micro-USB port for an optional AC adapter, but this is not standard. Always use high-quality alkaline batteries; rechargeables may not provide stable voltage, causing erratic temperature readings.

Q: Can I install this faucet on a sink with three pre-drilled holes, or must I cover the extras?

A: Yes, you can absolutely install a Single Hole Pull-Out Kitchen Faucet with Digital Display on a 3-hole sink. Xinbangye includes a decorative deck plate (escutcheon) with most models that covers the two unused holes. The plate measures 8.5 inches long and 2.2 inches wide, fitting standard 4-inch and 8-inch spreads. When installing, place the rubber gasket between the plate and the sink to prevent water seepage. If your sink has a 6-inch spread, you may need an aftermarket universal deck plate—measure carefully before purchase. Never leave open holes, as they allow debris and moisture to damage the cabinet below.

Q: What should I do if the digital display shows an "Err" code or incorrect temperature after installation?

A: An error code on the Single Hole Pull-Out Kitchen Faucet with Digital Display typically indicates one of three issues: (1) the temperature sensor cable is pinched or not fully inserted into the control box—check under the sink for kinks; (2) the water heater and cold supply are reversed—swap the hot/cold connections at the valves; (3) the battery voltage is too low, even if the display turns on, because the sensor requires stable 6V. Reset the unit by removing batteries for 30 seconds, then reinsert. If the error persists, run water at full hot for two minutes to flush air bubbles that may interfere with the thermistor. For Xinbangye units, pressing and holding the mode button for 10 seconds forces a factory recalibration—this resolves 90% of reported errors.

Final Checks and Maintenance

After successful installation, run the faucet for five minutes to flush any debris from the supply lines. Wipe the digital display with a soft, damp cloth—never use abrasive cleaners, as they scratch the LCD surface. Inspect the pull-out hose monthly for kinks or wear. The Xinbangye Single Hole Pull-Out Kitchen Faucet with Digital Display comes with a 5-year warranty on the cartridge and a 2-year warranty on the digital module, giving you peace of mind.
