Keep it upright
20 lb tanks are designed to stand on their foot ring. On their side, liquid can reach the valve and discharge as a jet.

Propane safety, the way we run our yards.
Propane is safe when tanks stay upright, outdoors, and leak-checked. These are the rules we follow at Lodi and Toms River — and the ones that keep a grill, patio heater, or jobsite from becoming a problem.
Six rules that prevent almost every incident
Store outdoors
Never store a cylinder in a garage, basement, shed without vents, or inside a vehicle — even overnight.
Valve off when idle
Shut the tank valve first, then the appliance knobs. Put the protective plug back on a disconnected POL fitting.
Leak-check with soap
Brush soapy water on the valve, hose, and connection. Bubbles mean a leak. Never test with a flame.
Give the grill space
Keep a lit grill or heater at least 10 feet from siding, windows, A/C units, and overhangs. Lid open before lighting.
Don’t use a bad tank
Skip any cylinder that is rusted through, deeply dented, scorched, or has a damaged valve. Exchange it — don’t DIY a repair.
Storage
Do this
- Leave tanks outdoors on a firm, level surface, out of direct traffic.
- Keep spare cylinders upright, valve closed, and away from doors and windows.
- Shade them from extreme heat when you can. Never put a tank on a grill while it is in use as “storage.”
- Commercial lots belong in a ventilated cage or lockable outdoor enclosure — like our yards.
Don’t do this
- Don’t store tanks indoors, in a basement, or in an attached garage.
- Don’t leave a cylinder in a hot car, trunk, or van.
- Don’t stack tanks on their sides or hang them by the collar.
- Don’t hide a tank in an unventilated deck box or plastic shed.
Connecting, grilling, and delivery day
Hookup
- Connect and disconnect outdoors, with the appliance off and the tank valve closed.
- Inspect the rubber seal / O-ring. If it is cracked or missing, stop and call us.
- Hand-tighten QCC fittings. Do not wrench a Type 1 (OPD) connection.
- Open the valve slowly, then soap-test before you light.
When we deliver
- Leave the empty tank upright and outdoors where we can reach it without entering the house.
- Clear the path: gates, dogs, and cars. Note the tank spot at checkout.
- We exchange 20 lb cylinders. Don’t offer a rusted, illegal, or non-OPD tank for fill if it shouldn’t be in service.
- After drop-off, leak-check the connection before the first cook.
Grill and patio heater
- Open the lid before you ignite a grill so unburned gas doesn’t collect.
- Don’t use a grill, turkey fryer, or heater inside a garage, tent, or enclosed porch.
- Don’t move a lit appliance. Keep kids and pets out of the work radius.
- When you’re done: tank valve off first, then knobs, then a few minutes to burn remaining gas in the hose.
- A tank that ices over hard during use, hisses at the valve, or won’t shut off is done — call us, don’t keep firing it.
