Kitchen Faucets: Common Types and a Structured Method for Installing a Water Faucet
A technical classification describing the characteristics of kitchen faucets in terms of shut-off mechanism, operating design, mounting position, and hole count, with a structured outline of installing a water faucet for common sink configurations. The scope includes types of kitchen faucets and kitchen faucet styles used in home kitchens.
Types of Kitchen Faucets
Kitchen faucets vary across four main dimensions: operation (manual/sensor), mounting position (deck/wall), spout form (high-arc/low/with spray), and shut-off mechanism (cartridge/valves). The table summarizes key differences within types of kitchen faucets:
| Type | Shut-off & Operation | Mount Position | Typical Hole Count | Engineering Notes |
|---|---|---|---|---|
| Single-handle mixer | Ceramic cartridge, single lever | Deck mount | One hole (escutcheon can cover 3-hole sinks) | Mixes hot/cold via one lever |
| Two-handle mixer | Two separate valves | Deck mount | Three holes | Align handles to spout |
| High-arc spout | Cartridge or valve | Deck mount | 1–3 holes | Extra vertical clearance for large pots |
| Semi-professional | Heavy-duty cartridge + exposed spring | Deck mount | Usually one hole | Multi-mode spray head |
| Wall-mounted | Valves within wall | Wall | Two wall outlets | Depends on in-wall rough-in |
| Touch/motion | Smart faucet via solenoid | Deck mount | 1–3 holes | Control unit with batteries/power supply |
| Pull-down kitchen faucet | Cartridge + internal flexible hose | Deck mount | One hole | Counterweight ensures spray head return |
| Pull-out faucet | Cartridge + horizontal hose | Deck mount | One hole | Suits shallow base cabinets |
| Kitchen shower spray faucet | Flow/spray diverter | Deck mount | 1–3 holes | Toggle between stream and spray |

How to Install a Water Faucet
This section outlines practical steps for installing a water faucet on the deck and on the wall, noting differences for a pull-down kitchen faucet and a smart faucet.
Deck-Mount (Single-Hole)
- Shut off angle stops; relieve pressure by opening the old faucet.
- Disconnect supply hoses and loosen the mounting nut with a basin wrench.
- Clean the sink surface and hole of silicone and mineral deposits.
- Place a gasket or a thin bead of sealant under the base.
- Feed hoses through the hole; secure the body with washer and mounting nut, aligning the spout.
- Connect hot and cold lines per markings; apply PTFE tape to metal threads as needed.
- For a pull-down kitchen faucet: route the flexible hose and install the counterweight at the marked position.
- Open angle stops gradually; inspect junctions with dry towels.
- Install the aerator; set any flow/temperature limiters if provided.
This method is commonly used across multiple kitchen faucets.
Three-Hole Installations (Centerset/Widespread)
- Mount the spout at the center hole and handles at the side holes.
- Interconnect handles and spout with internal link hoses per the manufacturer’s diagram.
- Verify tightness at T-junctions and internal couplings as part of installing a water faucet.
Wall-Mounted Faucet
- Determine height and centerline aligned with the sink.
- Provide two wall outlets at 150–203 mm on center (model-dependent).
- Use eccentric adapters to correct minor offset.
- Apply thread sealant; tighten unions evenly to keep the spout level.
- Pressure-test before installing trim covers.
Smart Faucet / Smart Water Faucet
- Insert the solenoid unit between the faucet body and supply lines.
- Mount the battery pack or power supply high and dry inside the cabinet.
- Follow directional arrows for flow; avoid sharp kinks in the hose.
- These requirements reflect the characteristics of electronically controlled kitchen faucets.
Post-Installation Checkpoints
- Base stability with no rotation of the faucet body.
- Dry connections after a staged 10–15 minute run.
- Smooth lever/handle movement without friction.
- Full return of the pull-down spray head to its dock.
- Stable flow without pulsation (pulsation indicates a clogged aerator or hose kink).
- Dimensions used conform to the stated 1/2-inch specification.
Common Errors During Faucet Installation
- Tightening the mounting nut before aligning the spout.
- Omitting the base gasket or using a non-sanitary sealant.
- Over-tightening leading to deck cracking or gasket damage.
- Reversed hot/cold supply connections.
- Missing counterweight on a pull-down kitchen faucet.
- Skipping cleaning of angle stops before reconnection.
- Not following solenoid wiring/plumbing instructions for a smart water faucet.
