Water Can Damage Your Propane System
If flooding is predicted for your area, turn off the gas valve at the cylinder or tank BEFORE the water rises. Do not turn the gas back on until the gas system and all appliances have been checked by a qualified service technician.
AFTER A FLOOD, contact a qualified service technician to check your propane system and appliances. A qualified service technician will likely have to do some or all of the following:
Replace the regulator and/or pressure relief valves if there are signs of water, dirt, debris, or corrosion.
Replace the automatic controls and appliance regulators on any gas appliances that have been under water.
Inspect and (if necessary) replace manual shut-off valves in gas piping, and perform tank testing of the system.
Clean appliance main and pilot burners and replace pilot orifices.
Clear Snow and Ice
You should clear heavy snow and ice from regulators, regulator vents, piping, tubing, and valves. Failure to do so can cause damage that could result in a gas leak. Appliance vents, chimneys, and flues also must be kept clear of snow and ice so appliances can vent properly. This is especially critical on the roofs of mobile homes.
Clear snow carefully. Use a broom rather than a shovel to avoid damaging any components. Also, clear the walkway and tank area so that propane-company personnel have ready access to your tank.
Something Doesn't Look Right After a Storm?
If your tank has shifted position; gas lines are bent, broken, or damaged; or you see something else unusual about your system or appliance, turn off the main gas supply valve on your propane tank, if it is safe to do so. Then contact your propane retailer or a qualified service technician.
