Plumbing question

One thing to keep in mind with the clear vinyl is that any light source will promote 'growth' inside the line, requiring periodic cleaning. This is ok as long it's accessible, which in most situations should be the case. On the other hand, you 'can' see what's going on inside the vinyl tubing as opposed to pvc or other tubing, where it's a mystery until there's a problem.

Also be very careful with math, a typical 3/4 barbed fitting doesn't have a 3/4 hole in it, I just measured one at.566 inside diameter that is a huge restriction when it comes to choking a 3/4 outlet pump. almost a 50% loss.

When I built my system I used rigid 1' PVC and a very flexable and reenforced PVC. No hose clamps were required on the flexable PVC to nylon hose barb connections. This system has been running for a year and a half without even a drop leaked. The hose is a little expensive but I feel well worth it. It also has a bend radius of 3" for the 1" with no possibility of collapsing.

3/4" NPT ID, .755" 50% less .375 3/4" barbed fitting ID .566. It's more like 30% less, but who's counting HAHAHA

You might want to do the Math again Dan, you are dealing with areas, it is a 43% reduction.

I know 3/4 is half of 1 1/2 but when it comes to pipe and volume the 3/4 will reduce the flow of a 1 1/2 pipe by 75%.
