Update and a couple more questions
The old pump is still working fine, just noisy as before. I've found the local Myers distributor through the help of a local plumber. In all seriousness, they don't know as much about pumps as I do since most of their customers are plumbers who already know what they need. They say that I don't need a convertible because the one pipe means that a shallow well pump will be fine. Is that correct?
Also, they only normally handle the shallow well in 1/2 horse. I had 3/4 and 1 horse in the convertibles. Is 1/2 horse OK? What, if anything, would more horsepower give me?
Any other advice would be appreciated. I'm going to break down and do this thing before that old pump forces the issue at an inconvenient time.
