I don’t have a question, but rather a comment on an earlier response to a question regarding leaving a broken anode in a water heater. The anode in the water heater in an old coach of mine disintegrated and left a pile of a coarse "sand" in the tank that got sucked into the system. It got into the toilet flush line and plugged the filter very frequently and was a raging pain in the neck. And it was very difficult to clean out. A long and tedious job. I don't think I'd want that portion of anode in my tank after that awful experience. Larry B. (Silver City, NM)
I agree Larry; it would be far better to remove that remnant of the anode, but unfortunately, there's really no easy way (if any), to accomplish that task. If I had to answer that question again, I would further recommend that the owner flush out the water heater every month as a precaution. I did allude to that in my earlier response. That, and possibly add a KDF-type filtration system to remove the finer particles that may exit the heater. I am perplexed, however, at how something isolated solely to the hot side of the fresh water system migrated to the toilet. If anything, you'd expect that "sand" to be expelled out through a hot faucet. Or simply lie dormant on the bottom of the water heater tank until flushed out through the drain. But your advice is well-taken. Experience is often the best teacher!
