Frequently Asked Questions
What is the difference between new, rebuilt and used propane tanks?
  • New tanks are brand new propane tanks, costing more than rebuilt or used tanks. They have a one-year manufacturer’s warranty.
  • Rebuilt tanks are used pressure vessels that have been shot blasted, repainted and equipped with new 250 PSI valves, gauge seals, screws and dials. They are pressure tested and come with domes. All new parts come with a one-year manufacturer’s warranty just like a new tank.
  • Used Tanks are as is. There is no warranty. The older the tank, the cheaper it is. Older model, used tanks that use 200 PSI working pressure are priced lower. Some are low profile tanks, meaning that the tank is lower to the ground and about two or three feet longer. Sometimes, the valves are not mounted on top of the tank.
  • Salvage tanks are as is, there is no warranty. These tanks can no longer be used for propane service due to damage or missing data plates. They are ideal for smokers, culverts, feeders and other miscellaneous uses.

Most tanks have a wet line in the tank.

Prices for rebuilt and used tanks are set according to several factors; the age of the tank, demand and the working pressure (200 PSI or 250 PSI). Both of these pressures are legal in Oklahoma. Some of our out-of-state customers require the 250 PSI and/or the U-69 stamp. The demand for these tanks determines the price.

Whatever you decide to purchase, we recommend purchasing your tank early in the spring or summer. Winter demand can result in rebuilt and used tank shortages.

What is a wetline or wetline hose?
A wetline or liquid fill line allows the liquid propane to transfer through a wetline hose to propane tanks, such as fuel tanks for trucks, tractors or forklifts. Barbeque grills use a wetline hose between the five-gallon tank and the grill.
What size regulator will I need?
The regulator is truly the heart of an LP Gas installation. It must compensate for variations in pressure and still deliver a steady flow of the minimum required pressure for all appliances. The safe, service-life of a regulator is fifteen years, however RegO┬« warranties its’ regulators for twenty-five years. If you are replacing an old regulator, remember to replace the copper pigtail as well.

The size of the regulator you need for your house will depend on specific factors. The following are guidelines to help in determining the size of regulators to use.

  1. Calculate the Total Load of BTU’s per hour by adding up the input ratings (BTU or CFH) of any appliances that will be using LP. Be sure to plan for future appliance ratings. Input ratings may be obtained from the nameplate on the appliances, or from the manufacturer’s literature.
  2. Measure the total length of piping (in feet) required for the appliance that is furthest away from the outlet of the regulator.
  3. The BTU plus length equals the diameter size of the pipe in use or to be used. Your propane dealer can help you determine which regulator will be most suitable for your actual load conditions and ensure proper installation.
What are some of the safety features you need to know about LP systems?
At the very minimum, it is desirable that you:

  1. Know the odor of LP gas and what to do in case you smell gas. Use the NPGA “Scratch/Sniff” leaflet available from your propane dealer.
  2. Know to never tamper with your LP gas system.
  3. Know that when protective domes are used to enclose regulators and/or valves, that the domes must be closed but not locked.
  4. Keep snowdrifts from covering regulators.
  5. Know the location of the cylinder or tank shut-off valve in case of emergency.
