expansion tank

hr

that sideways mounted expansion tanks have a shorter life expectancy then nipple up position. Does anyone else?

Mounted on their side, I have seen them last 20 years and more. Not bad for a tin can ;)

I'm more concerned about tanks mounted without adequate support. Like hanging from the nipple. Ever have a waterlogged one fall on your foot?

Connect them to a non barriered tube, high temperature hydronic system if you want to witness a short life span :)

up, down, or sideways

I've seen them mounted in every possible position, but does it really matter?

The Amtrol instructions seem to say mount with the inlet up. I can see that might be the best practice, but is there a down side to mounting an expansion tank sideways? Strapped sideways under a stand would be space saving.

So, what's the consensus?

The only real concern by the manufactuerers

is that if mounted where air can get trapped in the inlet then the bladder can dry and become porous

That's my understanding too. The only other thing I would add that the manufacturer looks down upon is mounting overhead in a joist bay..

I with ya HR on that one

I had a #60 Extrol come down and catch my fingers on a piece of angle iron didn't break anything but I was quite a while getting all my fingers to move normal again.
