Our local farm store sells the H&W brand. The used to be good when they soldered the bottom seam. Lately they just use caulk. That leaks badly.
I bought one of the H&W brand tanks and about a year and the seam started leaking. That was about 4 years ago. Still using the same tank but I drained it and sprayed flex seal on both sides. Hasn't leaked a drop since.
