Buying a new home is exciting, but before you fall in love with the kitchen cabinets and countertops, don’t forget to check one important thing — the kitchen plumbing. If the plumbing isn’t right, it can lead to expensive repairs later.
Here’s a complete kitchen plumbing checklist every home buyer should go through before making the final decision.
1. Inspect Under the Sink Area
The first place to look is under the kitchen sink. Open the cabinet and check:
- Are there any signs of water leaks?
- Is there mold, mildew, or a musty smell?
- Are the pipes rusted or corroded?
A clean, dry area means the plumbing has likely been maintained well. But water stains or odors can be a red flag.
2. Check the Faucet and Water Flow
Turn on the kitchen faucet and observe the water pressure. It should be steady and strong. Low water pressure might mean clogged pipes or leaks in the system.
Also, move the faucet around. If it’s loose or wobbly, it may need tightening or replacement.
3. Examine the Sink Drainage
Fill the sink halfway with water and then let it drain. Does the water go down quickly, or is it slow?
Slow drainage may indicate a clog or poor pipe design. Make sure there’s no gurgling sound, which can signal air or venting issues in the plumbing.
4. Look for a Garbage Disposal Unit
If the kitchen has a garbage disposal, turn it on and listen. It should work smoothly without loud noises.
Check for leaks or signs of rust under the disposal unit. If it smells bad, it could be a sign that it hasn’t been cleaned or used properly.
5. Inspect the Dishwasher Connection
Dishwashers are connected to the kitchen plumbing system. Check:
- Is the hose connected securely?
- Are there any leaks near the connection?
- Does water drain properly from the dishwasher?
A leaking or poorly connected dishwasher line can cause damage to the cabinets and flooring over time.
6. Hot Water Supply to the Sink
Make sure the kitchen has both hot and cold water coming from the tap. Turn the handle to hot and check how long it takes for warm water to flow.
If it takes too long or never gets warm, the water heater might be too far or there could be a plumbing issue.
7. Shut-off Valves Are Working
There should be shut-off valves under the sink for both hot and cold water. Turn them gently to see if they open and close properly.
If the valves are stuck or missing, you may have a hard time turning off water in case of a leak or plumbing emergency.
8. Water Supply Pipes Material
Check what kind of pipes are used for water supply in the kitchen. Common materials include:
| Pipe Type | Durability | Notes |
|---|---|---|
| Copper | High | Long-lasting, but expensive |
| PEX | High | Flexible and modern choice |
| PVC/Plastic | Moderate | Budget-friendly but limited |
| Galvanized Steel | Low | Old and prone to rust |
Old homes might have galvanized pipes which can rust and reduce water quality. Newer materials like PEX or copper are preferred.
9. Signs of Water Damage in Cabinets and Floor
Look closely at the kitchen cabinets near the sink and under appliances. Are there soft spots, peeling laminate, or water marks?
Also, check the floor near the sink and dishwasher. Water damage in these areas can point to past or present plumbing issues.
10. Check for Any Plumbing Code Violations
This may not be easy for every buyer, but if possible, ask a plumber or home inspector if the kitchen follows local plumbing codes.
Improper slopes in drain lines, missing vents, or illegal pipe materials can lead to major headaches later.
Conclusion
Kitchen plumbing is often hidden behind walls and under cabinets, but it plays a huge role in how your kitchen functions. Before you buy a home, make sure the plumbing system is working well to avoid costly repairs in the future.
Taking the time to go through this simple kitchen plumbing checklist can save you from plumbing nightmares later on.
