<strong>Yahoo Message Number: 16307</strong>Under out linen closet is a large tank (5 gallons?) that seems to be attached to the water system and has a pressure gauge showing 44PSI. <br/>I am assuming that is an accumulator tank? I've looked at the plumning schematics in the owner's manual and this tank doesn't seem to show up. If so, does it seem reasonable that the gauge would be filled...
