Propane (LP) System Leak Inspections
As spring approaches, you should plan to have your RV’s propane system inspected for any leaks before you begin your camping season.
DISCLAIMER: We recommend this work be done by a trained technician, unless you have the proper equipment and full understanding of how to perform this test. Your dealership may offer a spring maintenance special and can perform this service for you.
WARNING: If a leak is found, due to safety concerns, repairs MUST be made before using your coach.
The best way to test the system is with a manometer. Another option is to apply soapy water that does not contain chlorine or ammonia on the brass fittings. Bubbles will indicate a leak.
The LP system includes all copper lines, brass fittings to each appliance, hoses, the regulator, and steel manifold lines with attached brass fittings.
During the propane system inspection:
- Propane regulators must have a vent installed at the 6 o’clock position and must be able to breath.
- Pressure needs to be set at 11" water column. A manometer or U-tube must be used to perform this test and adjustment.
- If a flame on your stove goes too high and then suddenly drops down, your regulator may be contaminated by fuel sediments. The only option is to replace it.
- If the pressure is too high, it affects performance, efficiency, and safety. If the pressure is too low, your appliances will not operate correctly.
NOTE: Use a pipe dope on black pipe or pipe with steel threads, and use Teflon tape on brass fittings.
