At the turn of the twentieth century, John A. Zurn purchased a backwater valve patent from Erie City Iron Works. The product prevented storm and wastewater from flowing back into a building’s drainage system. From that start, Zurn has expanded to include a complete offering of building water safety, site drainage, behind-the-wall systems, and front of wall fixtures and trim. In the construction industry, Zurn’s trench drain system is very popular and enables pre-fabrication and modular construction. AR Chambers carries Zurn’s Z886 Trench Drain system and accessories.
