Lately, my wife and I have been having trouble with our water heater. Over the last few months we've been finding the blower blowing but no gas running along with it to actually heat our water. Recently, the gas would turn on for only 10 minutes before shutting off, leaving the blower going, sometimes all night while we slept.
You don't fully appreciate what you have until you're threatened with losing it, especially hot water. So my wife leapt into action. She engaged in a dialogue with a repair company (which sent their crack water heater man out several times) as well as with our water heater manufacturer. A flurry of emails and phone calls were exchanged. She read online manuals and articles, trying to diagnose our problem. She went over her findings with me in painstaking detail, and we finally figured out the blower wasn't generating enough pressure to safely expel the carbon monoxide waste so the gas was actually being shut off by the unit appropriately. But because the water temperature hadn't reached its set point, the blower would continue to run, further wearing it down and decreasing the amount of pressure it could generate, exacerbating the problem.
So my wife called in a plumber to drop a camera into our water heater exhaust pipe to see if some obstruction had arisen that had increased the resistance to flow just enough to cause the safety switch to shut off the gas to prevent a dangerous build up of carbon monoxide. We found an excessive build up of lint in our drier line, but nothing in our water heater line.
As I watched my wife struggle with these issues, I couldn't help but think of a famous Buddhist quotation: "The lion king is said to advance three steps, then gather himself to spring, unleashing the same power whether he traps a tiny ant or attacks a fierce animal."
HOW A LION ATTACKS
A lion doesn't judge the strength of its opponent and adjust the force of its attack. It aims to completely overwhelm its adversary every single time with the full force of its might. It doesn't matter how strong or weak its adversary is. The lion doesn't care. It's intimidated by nothing because it considers itself supreme---that is, supremely capable.
Without a doubt, this describes my wife perfectly.
APPLYING THE LION'S STRATEGY
Many benefits exist to taking the lion's approach to solving problems.
In the end, my wife persevered and the water heater manufacturer relented by sending us a new blower. When the water heater man replaced it, he found caulk had been inappropriately applied to the outflow manifold as well as to the joint between the blower and the outflow pipe, narrowing the diameter of the outflow path in two places just enough to increase the resistance to flow beyond what the blower could handle. When he replaced it with the new one, the pressure increased by nearly 50%.
Though discouraged at several points, uncertain if we'd ever be able to diagnose the problem much less fix it, my wife never gave up, never slowed the pace at which she attacked the problem or decreased the energy she brought to bear on it, reminding me once again of this most basic formula: tenacity + 100% effort = victory.
