If not, you might want to look at the cost and get it. I saved about $50/year over the last 20 years. Last night the sewer main backed up, and raw sewage gushed from the basement toilet for about 3 hours, from 10:30 until about 2:45, while the township worked to clear it. Today the Servpro guys are here, and the bill, after a call to State Farm confirming that we don't have the coverage, is $9887.46. That is WITHOUT replacing any of the damaged furniture, or electronics, or the carpeting, or any of the contents. That's just to fix and disinfect the house and garage.
Now, you might say that there is far, far less than a 10% chance that your sewer would ever back up, or even a 5% chance, allowing for $10000 worth of content, and I would agree with you; the odds are pretty slim. BUT, I would counter by saying that you'll never miss the $4-$5 a month, and if you ever have a claim you'll be glad you spent it.
