The water in one of our rental farm houses had a pretty bad sulfur smell. It was coming mainly from the hot water. We replaced the anode in the hot water tank with one made of aluminum and zinc, and it helped a lot. The anode had a sticker on its box that said, "For stinky water". No joke.
No way let him build on your property. As others have said too many issues down the road. In my area zoning laws do not allow an out building within 20 feet of a property line. My new shop is 21 feet, and the inspector actually measured it.
I don't know the answer to your question, but another place to ask is the, Firewood and Wood Heating, section of the The Forestry Forum. I have a 30 year old Ashley that does have fire brick.
I still use a B&K Precision that I bought at least 20 years go. It is used weekly and still going strong. I have been very pleased with it. However, if I was looking for a hand held meter today it would be one from Fluke. I don't believe that the B&K meters are near what they once were.

I looked into getting one after we lost power for two weeks due to an ice storm a few years ago. Cost wise I couldn't justify it at the time. With the cost of diesel and the cost of the machine it didn't seem feasible. What with our 6.5k generator working good enough for us to get by with.
My Dad bought a compressor for farm use in the late 70's. He was never the first on the block to get something. I have had my Porter Cable branded compressor for about 15 years and it is the most used thing in my shop.
Marshalltown makes masonry, concrete, drywall, and other tools along that line. I use their drywall tools and prefer them to any other.
