If you have galvanized pipes, the problem with your low pressure water could be the pipes themselves. When they rot, the rot from the inside in. Thus, you won't see any damage until you cut the pipe open...at which point, you'll see all the rot clogging up the pipe. I had this in a house once. And it was the hot water pipes. I started in the bathtub, and ended up replacing all the pipes...allllllllll the way to the street. It was a nightmare.
For the rot in front of the tub: If you're planning on replacing it anyways, you can always try to old "If you can stab a screwdriver through it, it's rotten" test. But that only works if A) you don't have tile, and B) you're already planning on replacing any linoleum (or whatever else you've got on top of the subfloor).
