Pilot Outage

We will bubble test all fittings and appliance connections, pressure test the system and relight all pilots.

It is our policy to inform you at the time of your call as to any possible charges related to out-of-gas situations, special trip charges or service charges.

General Tank Considerations

Propane gas is a safe, environmentally friendly fuel that offers significant value to end-users when compared to other fuels. There are however, some general considerations that need to be recognized when installing propane tanks.

Propane tanks that are 325, 500 or 1,000 gallon capacity must be at least ten feet from any door, window, opening, building or property line and a minimum of ten feet from any source of ignition or combustible materials.

Propane tanks that are 120 gallon capacity must be at least three feet from any door, window, opening or property line and a minimum of ten feet from any source of ignition or combustible materials. It is allowable to position these tanks next to a building.

Propane tanks that are smaller than 120 gallon capacity must be at least three feet from any door, window, opening or property line and a minimum of five feet from any source of ignition or combustible materials.
