Sewer Clean Out
PVC glue joints are the most common type in joining two pieces of PVC pipes. When two different pipe materials join another type of coupling must be used. The approved fitting in the state of Louisiana is called a No-Hub fitting as shown here. A No-Hub fitting consists of a rubber gasket incased in a metal band with two or four hose clamps. A four band No-Hub is used here.
Mock Plumbing always uses four band No-Hub couplings as it provides a both a stronger fitting and a larger seal than a two band No-Hub. Details as described above will make the difference in a sewer line lasting 20 years versus 10 years.
