Both of you offer wise council, thank you. I'm gonna hardline it, since I have the PVC
anyways. I also bought myself a union to be used before the ball valve. Plumbing isn't my forte, so hopefully these guys I have coming tomorrow can set me up right.
Now, here's another question. Comparing an in-line pump to a submerged pump, what's the difference in temperature that's produced? I've been spooked by some stories claiming that a submerged pump can really heat up a tank, but those accounts were in smaller systems. What do you guys think? Anyone have experience with this?
