Resin coating to the threaded part is incomplete. After mounting two weeks later it was removed and confirmed that there was considerable rust as expected. In that case, I think that purchasing stainless steel ones would be cheaper instead. Incidentally, the water supply of the installation house is using well water. Esrocote may be better than this product. It was disappointing though I was expecting it because it was a product of jilly.
