Rough Plumbing Inspection Checklist

1. Check all exposed piping for signs of corrosion:

During a rough plumbing inspection, any visible piping should be closely examined for signs of rust, corrosion or damage. It’s important to check every crevice, corner and joint of the pipe because even small amounts of corrosion can quickly spread throughout the system and cause larger problems. Furthermore, any areas where the piping is touching non-plumbing materials should be checked to ensure a strong seal.

2. Inspect any insulation around pipes and fittings:

Insulation is an important component of a successful plumbing system, as it helps prevent freezing in cold weather and helps reduce the risk of hot water scalding or burns. During a rough plumbing inspection, all insulation should be inspected for damage or gaps that could allow air drafts or moisture infiltration into the system.

3. Look for leaks or excessive condensation on pipes, valves, and fixtures:

Leaks can often be difficult to spot, but if not addressed immediately they can cause significant water damage and mold growth within a home’s walls and floors. During a rough plumbing inspection, all pipes and fixtures should be checked for signs of water leakage or excessive condensation.

4. Examine water pressure in all hot & cold lines:

Water pressure is an important factor when it comes to the performance of a plumbing system. Too much pressure can damage fixtures and lead to leaks or broken pipes, while too little pressure can cause poor performance of sinks, showers, toilets, etc. It’s important to check the water pressure in both hot and cold lines to ensure proper operation.

5. Test the flush mechanism on toilets to ensure proper operation:

Toilets are one of the most commonly used appliances in any home, so it’s important to make sure they are functioning properly. During a rough plumbing inspection, the flush mechanism should be tested to ensure that it is working correctly and not leaking or overflowing.

6. Verify that all sink drains are properly connected and vented:

Sink drains must be securely connected in order for them to function properly, and each drain should also have an appropriate venting system. During a rough plumbing inspection, these connections should be visually checked to ensure there are no signs of leakage or damage.

7. Ensure proper installation of any garbage disposals or dishwashers:

Garbage disposals and dishwashers require careful installation in order to operate safely and efficiently. During a rough plumbing inspection, these appliances should be checked to ensure they are properly connected, sealed, and vented. Furthermore, any hoses should be visually inspected for signs of leakage or damage.

8. Check the gas line connections throughout the house:

Gas lines are an essential component of any home’s plumbing system, as they provide a safe and efficient way to transport natural gas into a home for heating and cooking purposes. During a rough plumbing inspection, all visible gas lines should be checked to ensure there are no signs of leaks or damage.

9. Inspect exposed electrical wiring near pipes or fixtures:

Any electrical wiring that is located in close proximity to plumbing pipes or fixtures must be inspected during a rough plumbing inspection due to potential safety hazards. All exposed wires should be checked for signs of fraying, corrosion, or damage that could lead to fire or shock risks.

10. Look at water heater temperature setting and inspect vent system:

The temperature setting of a water heater is an important factor when it comes to energy efficiency and safety. During a rough plumbing inspection, the temperature should be checked to ensure it meets local codes for safety and efficiency. Additionally, any vent systems connected to the water heater should be inspected for proper installation and functionality.

11. Inspect the sump pump to ensure it is functioning properly:

A sump pump is an important part of any home’s drainage system, as it helps to prevent flooding in basements or crawl spaces. During a rough plumbing inspection, the sump pump should be tested to ensure it is functioning properly and not leaking or overflowing.

12. Make sure all water shut off valves are functioning correctly:

Water shut off valves are an essential part of any home’s plumbing system, as they can be used to control the flow of water in case of an emergency. During a rough plumbing inspection, all accessible shut off valves should be tested to make sure they are functioning correctly and not leaking.

13. Test all faucets for proper flow and pressure:

Faucets are an important part of any home’s plumbing system, as they provide easy access to clean drinking water. During a rough plumbing inspection, all faucets should be checked for proper flow and pressure in order to ensure that they are functioning correctly.

14. Ensure that the home’s main water supply is shut off at the appropriate time:

The main water supply of a home is an important part of the overall plumbing system, and it should be shut off when necessary in order to prevent potential flooding or other damage. During a rough plumbing inspection, the state of the main water supply should be checked to make sure it is turned off at the appropriate time.

15. Examine any visible piping for signs of rust, corrosion, or damage:

Pipes are an essential component of any home’s plumbing system, and they can become damaged over time due to wear and tear. During a rough plumbing inspection, all visible pipes should be examined for signs of rust, corrosion, or damage that could lead to leaks. Any issues should be addressed before the final plumbing inspection is conducted.
