Hmmm. That kind of makes sense.

Still it seems to me that if the whole rig is under the mash bed there should not be a problem. Also, as it is suction and not pressure, the need for soldering still seems pretty slim to me.

It's not really that slim. As the wort/water level drops below the topmost slip joint, the tendency to pull air is high due to the siphon being created by the outflow.

This is a Hot Liquid Tank, not a Mash Tun. There is no mash bed.

Exactly, again, there is no mash, just water, so a leak at the first joint would allow the pump to pull air which is easier than water.
