TQ. I will get my parents a unit very soon.

This is a dead-serious no-bullshit sharing:

Was visiting parents and washing up my coffee mug at the kitchen sink before I left for the airport. I smelled a bit of gas. Immediately went to the gas tank and daubed soapy water at the valve and regulator area. The valve of the tank was leaking..a few soapy bubbles appeared there. Rinsed my hands and yelled at my dad to open the front door. I disconnected the regulator, grabbed the tank and ran to the garden. Put the gas tank in the middle of the garden and ran back in to open all the kitchen windows and door to the back yard.

My dad phoned the gas delivery man, and to his credit he arrived within 10 minutes. My aged parents could not smell the gas; their sense of smell had deteriorated over the years. The delivery man grumbled at us, asking why use up about half a tank before complaining about the leak. I told him It started leaking very suddenly and if he didn't want to replace it, I'll pay for a new full tank. As we spoke, the gas tank let out a loud FFFSSSHHHHHH and the valve flew off, emptying the tank very fast. Delivery man stopped grumbling and gave us a new tank. I did the soapy water test in the new tank at least 5 or 6 times before bringing it into the house.

Had I left for the airport a little bit earlier, I think my parents would have been in danger. Till today I get gooseflesh thinking about that narrow escape. Gas leak alarms are available in Shopee, and I urge all to use them. A bit of money spent for safety is well-worth it.
