Eliminating Leaks and Restoring Drainage Systems
Drain-Waste-Vent (DWV) systems are vital for removing wastewater and preventing sewer gas from entering occupied spaces. In aging buildings, these pipes often corrode, crack, or clog—especially in Hawai‘i’s salty and humid conditions.
Cast iron pipes prior to 1950 typically have a lifespan of 80 years. The cast iron pipes that were installed in Hawaii’s high rises in the 1960's to 1980's have a 50 to 60 year life span.
When your building goes from one to two leaks a year to six to eight leaks a year, it is time to replace your DWV pipes.
