An RO (reverse osmosis) air gap faucet may leak for several reasons:
- Loose connections: If the connections between the faucet and the water supply lines are loose, it can cause leaks. Check all the connections and tighten them if necessary.
- Damaged O-rings: The O-rings inside the faucet can become worn or damaged over time, which can cause leaks. Replace the O-rings to fix the problem.
- Clogged air gap: If the air gap is clogged, water can overflow and cause leaks. Clean the air gap thoroughly to ensure that water can flow freely.
- Cracked faucet body: The faucet body can become cracked or damaged, which can cause leaks. In this case, you may need to replace the entire faucet.
Here are the steps to fix a leaking RO air gap faucet:
- Turn off the water supply to the faucet.
- Disassemble the faucet to access the internal components.
- Inspect all the connections and tighten any that are loose.
- Replace any damaged O-rings.
- Clean the air gap to remove any blockages.
- Check the faucet body for cracks or damage. If the faucet body is damaged, replace the entire faucet.
- Reassemble the faucet and turn on the water supply.
- Test the faucet for leaks by running water through it.
If the faucet continues to leak after attempting these steps, you may need to call a professional plumber for further assistance.
