expansion tank piping

Quite possibly talking about a thermal trap or to be more precise an anti-thermosyphon loop. They are usually 1 foot long. If this is what he means I don't know but I do make these (traps) all the time every time.

Why would you make a trap before you tie into an expansion tank with a bladder?

Thermal trap

This was a thermal trap. What is its purpose?

We have thermal loops on most of our large heating systems for the bladder expansion tanks. I think its because room temperature water takes up less space than 200 degree water so the tank can do a more efficient job accepting the pressure increase as the water heats up in the system.

thermal trap

Going out on a limb here, but they keep the hot water from migrating into the system from gravity.
