Testing Your Propane Piping System for Leaks

April 1, 2022 – ,

Some of our customers asked us why we need to do a leak check when their propane container runs out. Safety regulations require our qualified technicians to perform a leak check before relighting your appliances after the filling of your container. Here’s why this is necessary.

When there is propane in your container, there is constant pressure in the piping system; when the propane is completely used up, the pressure in the piping will eventually drop. Loss of pressure could create a leak because of the expansion and retraction of the piping compound that can occur in the system. Whenever there is an interruption in service — such as running out of propane gas — a leak check will reveal any potential leak in the piping, which we can then correct.

To avoid running out of gas, ask us to arrange for automatic deliveries. There is no extra charge for this service if you qualify, and you won’t have to worry about the inconvenience of running out. The service cost of having a leak check performed is also waived.

With automatic delivery, Paraco estimates when you need a propane delivery based on your historical usage and house size. If your delivery needs are more unpredictable and vary significantly from month to month, we can install a propane tank monitor to ensure your propane is delivered right when you need it so you never run out.

Feel free to contact us with any additional questions! We’re happy to help.

    I’m glad you explained why it is important to check the pressure levels in a propane tank to ensure that there are no leaks. My parents want to get propane appliances for their cabin. I’ll be sure to tell them that they will need to get a professional to test their tank regularly.

    I tested my propane gas line into my valve control. I’m having a hard time with the pilot lighting. I’ve changed out assembly and valve control. Still can’t get the pilot to light. It seem the pressure coming is low. Let know your thoughts.

      Hi Cornelius! Propane equipment should only be worked on by a trained and qualified individual especially as it comes to gas flow. Low-pressure issues can be caused from a myriad of reasons. The best option is to set up an appointment for a service technician to visit and diagnose. If you are a Paraco customer, call us on 800-647-4427 to set up a technician visit.
