And you may dust off your hands from another job well done. Glad you didn't need to replace the water heater. I had to light our pilot light yesterday morning, having noticed that the water was not hot when I washed up and dressed. With an electrical lighter, it isn't the job that it once was.

Hmm, my water heater doesn't have a pilot light, it is self lighting. I don't know how that works since it doesn't have any electrical wires running to it.

I was surprised the first time our pilot light was blown out. I didn't know our heater had one (and it cost me $80 to find out by calling out a service tech - lol.) A piezoelectric igniter needs no external electrical source.

When a quartz crystal (such as may be in a piezoelectric igniter) is compressed, it produces a voltage (over 10,000). I don't know how your igniter works; but, when I push the igniter button (to light the pilot light), it releases a spring loaded striker (I hear a "thunk") to hit the crystal. The voltage is led to the pilot light via thin wires and the voltage produces a spark in the gap between the wires, lighting the gas.

The same principle is used on vinyl audio recordings - making the varying grooves in the platter by subjecting a crystal to varying electromagnetic fields, and playing back by having a needle follow the grooves in the platter, thereby producing distortions in a crystal that converts the forces to varying magnetic fields. I know...you didn't really care.

Funny because I had always assumed that my water heater had a pilot light, until I changed propane companies. The tech was making sure my water heater would start (after lighting the pilot to my boiler), and I tried to hand him a long match. He was kind in not laughing at me :)

If each of us laughed every time someone else showed their ignorance, we would all spend all of our time laughing. We are all (in my case, very) ignorant of some things!
