What Size Water Line for House?
Water lines are one of the most important parts of your home’s plumbing system. They are responsible for carrying clean water to your fixtures and appliances and draining waste water away from your home. Because of this, it is important to choose the right size water line for your home.
The size of your water line is determined by the number of fixtures and appliances in your home, as well as the water pressure in your area.
A typical home with two bathrooms, a kitchen, and a laundry room will need a 1–inch water line. However, if you have a kitchen with a dishwasher and a laundry room with a washing machine and dryer, you will need a 1 1/4 or 1 1/2 –inch water line.
If you are not sure what size water line you need for your home, you can contact a local plumber or water line contractor. They will be able to assess your needs and recommend the best size water line for your home.
