Identify the Source of the Leak

Identifying the source of a leak in a commercial faucet involves checking several potential areas. Here are the common sources of leaks in commercial faucets:

• Loose Connections: Check for loose connections at the base of the faucet, where it attaches to the sink or countertop. Tighten any loose nuts or bolts.
• Worn-out Seals or O-rings: Inspect the seals and O-rings inside the faucet assembly for signs of wear or damage. Replace any worn-out seals or O-rings to prevent leaks.
• Corroded Valve Seats: Check the valve seats for corrosion or mineral buildup, which can cause leaks. Clean or replace the valve seats as needed.
• Faulty Cartridge or Valve Stem: If the faucet has a cartridge or valve stem, check for any defects or damage. Replace the cartridge or valve stem if necessary.
• Cracked or Damaged Components: Inspect all components of the faucet, including the spout and handles, for cracks or damage. Replace any cracked or damaged parts.
• Water Supply Lines: Examine the water supply lines connected to the faucet for leaks or damage. Tighten any loose connections and replace any damaged supply lines.
• Improper Installation: If the faucet was recently installed or serviced, check for any installation errors, such as incorrect alignment or missing components. Reinstall or adjust the faucet as needed.
