Thanks to Al and Mark my problem is solved. A cold water line running aft behind the port fuel tank and the master cabin head cracked at a joint causing my leak and loss of pressure. We replaced the old line with new and the problem is solved. As mentioned above the best part was having a few cold ones while waiting for our fix to fail! It didn't... Again, thanks to Al and Mark. The fix would have been difficult for one person.
