I moved into my first house about 2 weeks ago. I found out in that time my valve for the cold water supply line for the washer does not let out water. How do I replace this? I tried the hot water supply valve and got a surprise face full of water if this tells you anything about my level of plumbing knowledge. I also discovered that a sink also leaks beyond the sink cabnets out the side and onto the floors, would tightening the pipes help solve this? Then I found out that my dishwasher leaks from the front door, has anyone successfuly repaired the seal on their dishwasher?
