I am trying to help remodle a basement. This house has many plumbing problems. The owner cant afford to hire a plumber. I know some basics and am trying to help her out. 1) Water Pressure. There is no water pressure to anything in the home. why is this, and what needs to be done to fix it? 2) When the water is turned on in the home, hot water constanly runs out the faucet in the bath tub. How do I fix that? 3.) The main level toilet wont really flush. I took of the lid to the tank, there was not a lot of water in the tank, and it takes it a very long long time for the tank to fill up. There is no pressure to the flush. 4.) the valve coming into the home for the water supply, contantly drips water when its turned on. Please help.
