Can you believe a spider has the ability to break a waterheater?

I know that sounds weird, but it true. I worked on two waterheaters that would randomly shut off about once a day. These are the newer style water heaters that have the flamed sealed, and you can see the pilot through the glass. I actually called the manufacturer and they sent me a brand new gas valve. Even after installing the new gas valve, the same problem persisted. Well it turned out that a spider web blocked enough of the air vents on the bottom of the water heater to cause the problem.

To fix the problem, I used a Shop-Vac, and put the vacuum holes so it would be a blower instead of a vacuum. Then I put the vacuum holes on top vent of the waterheater. This blew the air through the waterheater and cleared the vents from the bottom of the waterheater.

I just thought I share this information, because this is one problem that was boggling my mind for about a week. I was ready to replace both of these waterheaters, until somebody suggest this solution. The older water heaters, the ones with the flame exposed and needed to be lite with a match, never had problems like this.

I believe it, gas (natural gas anyways) is extremely low pressure, my gas from my meter is only 6 in/h2o, im sure the WH regulator reduces it even further.
