Ensuring kitchen sink fixtures are sufficiently vented is important for guaranteeing the efficient removal of waste from your property, it has been suggested. Writing for Canwest News Service, Mike Holmes stated that while drains remove refuse and water away from the house, without proper venting fixtures cannot breathe. He noted If your sink drains slowly, it might not be plugged. The problem could be improper venting, or your vent stack could be blocked with leaves.Vent stacks usually protrude from the roof, Mr Holmes added, allowing gases to escape and equalising the system by providing pressure. During a renovation project it is particularly important to make sure a contractor properly vents the system otherwise potentially dangerous gases can seep into the home.According to HeraldNet, making the right kitchen improvements not only increases the value of a residence, it can add to the owners quality of life.
