When mounting an expansion tank (an Extrol Model 15) -- in the piping

for a hydronic coil in a air handler -- is it OK to mount it

horizontally?  The contractor mounted it that way, and I just noticed

that it says on the expansion tank to only mount it vertically.  If this

is going to be a problem, I'd like to get it fixed before he's finished

with the job.

    It should be

    mounted as instructed simply because it says so. It really does not matter in the final analysis however. The concern is if it gets water logged in the horizontal position it may snap off and you would have a lot of water.

    Thanks for the reply!  I hadn't even thought about what might happen if the tank were to become too heavy for its fitting.  I'll definitely have the tank reoriented.
