I work for a heating service co. and last year we were changing ex-troll tanks faster then the supply house could get them. We had 3 supply houses bringing 6-8 every other day. More than half had bladders failed and the rest were rotted out. Cheap steel, I have seen 1/8" steel with pin holes that looked like someone drilled a hole in it with the rest looking almost new. Black pipe from China is junk we had bought a bunch and we couldn't cut threads in it, just ripped the steel out or broke the dies. Now we only get pipe from USA or Canada and have had no problems. Import pipe rusts with big flakes the US pipe will have fine coating of rust. Import steel sucks
This year I had to change a oil pan on a Cummins diesel, the whole side was rotted under the paint. If the car co stopped dipping car bodies, cars would rust away before they were paid off!.....Do I sound like Smitty?
I don't know where the Amtrol steel comes from. They say the unit is manufactured in the US but I don't know if the components are also from the US. I know that the quality of Chinese steel is so-so. Taiwanese goods are much better. I was once told by an engineer that worked for National Hand Tool that very high quality tools can be had from Taiwan, but like elsewhere, they are more expensive. Quite often, those shopping for import goods are looking for cheap or cheapest, thus the quality goods are not requested. National Tool imported our socket and ratchet line. They carried a lifetime warranty with an immediate no-quibble replacement policy. The rate of return on them is not any higher than our former line from Danaher. The quality difference is in the finish. The Danaher look and feel much nicer.
I will be installing a Chinese or Taiwanese made Watts pressure tank. I will report on its quality.
I appreciate the report. Thank you.
