OK -- I don't mean to pick here -- but there must be some disclaimer.

Last season some handyman jerk-wagon was trying to insult me for mixing fittings on a low bid install that made use of what was on site.

Here your doing an install for factory propaganda and I count several types in a short vertical foot on that supply line
-- we have
- sand cast - Mal-able - Galvanized - Black - copper - bronze -

WTF :? The short nipple is already covered in rust from electrolysis. Your air scoop is too close to the nearest elbow for fault tolerant flow.

At least paint that stuff so it looks like all black!

Ok -- maybe I am picking......... :roll:

The union leaked over a weekend when the fire went out and it cooled down. That's what caused the rust. Hasn't leaked since, but paint is a good idea. That galvanized tee is there because I needed one in a hurry and the supply house was about a week out and that's all I could get. There are no less than 20 auto air vents in the system, plus numerous manual vents. Air was never a problem from day one.

The return line is 1 1/2" at the first valve and reduces to 1 1/4" after the first valve.

You know how you look at something every day and don't even see it anymore? Now I see it.

Wow. Looks like it was a design contest, build it out of what's left over in the plumbing truck. I'm with Sting on this one. Just offensive to my engineering mind. Design it right, build it once.

I used black pipe. Wrong or Right it works good for my needs. It was brought up that I should have turned the two T's so I could rod out the vessel.
