What you do not get is how pipe size reduction affects flow no matter
what the fluid or gas is that is inside.
I have already proven it years ago on site, only an idiot would
introduce a restriction into a piping system. No matter what the total
size of the job is.
Is there a chance that the restriction will not bother anything? Yes,
on small systems with low water consumption.
But, if the journeyman is worth his salt he would not take a chance
knowing the problems that can arise and just do the job correctly.
Those pictures of the plumbing at your house is a good example of poor
water flow. Every 90 degree angle reduces the water flow by the
equivalent of 10 feet of straight piping. 45 degree elbows equal 5
feet of piping. Which is why long radius 90 degree elbows are made.
Yes, piping is part of the HVAC trade and you can get knowledgeable
people and you can get backyard mechanics with no training and little

By the way, you would do well to look for a good plumbing contractor
based on your pictures, with all those joints in the plumbing and you
are concerned about one size increase on a dielectric nipple?
Uh, galvanized pipe is not "leaded". Lead pipe is just that, pipe made
out of lead. Galvanized pipe is dipped in or plated with zinc, not
lead. The major source of lead in residential plumbing is the solder in
copper joints (assuming that there's not lead pipe coming from the
street, as is the case in Flint, among other places), but in recent
years lead-free solder has come into use.
Not totally true, my tank has galvanized nipples that goto the tank.
They had plastic inserts, that I did not understand at the time and
removed thinking they were protective plugs.
They are to keep the water from the leaded galvanized pipe.
They are glued in, and I could not remove the nipples, even with heat.
My old water tank had galvanized nipples too, w/o the plastic inserts. I
guess before they realized that. So hot water is not always the same as

Yeah, it's kind of a non-issue isn't it?
All the newer single ball valves I've seen allow for turning to the cold
water input hole without passing over the hot water hole. I think some
older ones may have had a different design. But even then, as you say,
it takes a millisecond to passover it.

Depends on how old your house is. While the hot water heater
tank is fine, there's some reason to think hot water can leach
lead out of lead pipes, or lead soldered pipes.
Personally I don't think there's enough solder exposed to the
water to cause a problem (altho century-old lead pipes is a
different matter), but if you're the super cautious kind you
might want to avoid drinking from the hot side.
