replumbing an old house
I have bought an old house with a lot of land at a good price, so it goes unsaid that I also have a lot of work to do on it. The idiots that owned the home before me screwed up a lot of things trying to fix them. I have old steel pipe for my water lines right now, some of them look like tree bark where the pipes have rusted, and flaked. No leaks from them yet, but there is a leak somewhere. In the bathroom that they added, it looks like they had a box of elbows and t's and were just trying to use up all of their supplies or perhaps just trying to fill in all of the area under the bathroom. I have lines running in every direction, and back again then over up and back again. It is crazy. I have never seen anything like this. The house needs leveled, but I don't dare set a jack under it until the old pipes are replaced. I have decided to redo the whole house. I believe the leak is underground off of the main going over to the faucet, but instead of digging up all of that dirt, I am going to just dig a trench from the box, up to the house, set an outside faucet by the steps instead of over at the side of the house. I guess what I reallly want to know, is this, is 1" pipe coming into the house, reduced to 3/4 branching to the bathrooms, and reduced to 1/2 coming up through the floor the norm? Is that where I will get my water pressure? and should I bring the main up out of the ground as soon as I get under my pier and beam house? I have two bathrooms, two outside faucets, a washer, and the kitchen, 42 feet from the box to the house, another 25 feet to our bathroom, then elbow over another 30 feet to get to the guest bathroom where the water heater is. Will 1" pvc suffice for this situation? thanks
