How water tank repurposing
Got two more hot water tanks for re-purposing and these two don't have the thick HDPE [I think] lining like the one in the thread above.
We cut the cover off and broke the insulation off the actual tank [a lot harder than the one on the topic above because it was sprayed directly to it, but there are some tricks that make it fast and easy, a 15 minute job].
These tanks had a lot of solids in the bottom, the cathode rods were pretty much gone, and there was not ANY of the calcium sludge I expected to find. Just sort of granules of some kind of silicon/rocky looking stuff that when dry could be poured out.
One of the tanks was short, maybe 30 gallons and the other was tall, abt 50 gallons. The inside when cleaned was PERFECT for storage of fuel or maybe even water, but because of freezing issues, I prefer plastic tanks for water.
For fuel, however, it doesn't get better and cheaper than this. Also, these tanks have a base and can stand upright vs. the first one that didn't.
It would be useful to get the proper tap from ebay to chase the threads on the approx SEVEN strategically placed holes that make these tanks useful in a vertical or horizontal [using a wood cradle maybe] position.
The surface of the tanks' inside was surprisingly, essentially perfect, inspecting with a Fenix flashlight all around, no signs of rust or any corrosion.
The folks replacing them probably wasted a total of $1000+ when they could have replaced the cal rod and maybe the heating elements and had many years more useful life.
