You mean...the 4" Carlsons?I wish you lived closer, I'd hand the stuff off to you for free.
Yes, a Carlson 4" pump that was at a used gear sale last summer. He bought on for himself and one for me, so then I didn't have much of a reason to pursue the DYI method.You mean...the 4" Carlsons?
Yeah, in my perusal of this questions the issue of irregularity of schedule 40 has come up a few times, which is something I hadn't considered. If you look at the pump linked earlier in this thread you'll see it uses sort of a flat gasket instead of an O-ring, which I'd think would be better in terms of small irregularities. But I'm guessing.
That fella's 4" looks like a pretty competitive deal to me, at any rate.
Looks like this guy has figured it out. He does 4 or 6 inch tubes.
