Do you have a faulty gas regulator at home? Or is your gas regulator giving out hissing sound?
Stop placing heavy objects on your leaking LPG cylinder regulators.
Why?
This does not correct the gas leakage.
Get the faulty LPG cylinder regulator, valve, and worn-out rubber seal/washer in the valve replaced to prevent the risk of fire or explosion.
Shaking your gas cylinders to know the amount of gas left inside your gas cylinder, is not only dangerous, but could cause it to explode.
Most times we shake our gas cylinders to know if it's finished or not, that is a dangerous thing to do. It could explode and be suicidal!
