Frequently Asked Questions

Zurn's combination deck plates use a manufacturing process that does not easily allow for custom product, therefore, it is challenging to accommodate unique center to center distances for this product.  The user should consider using individual drains as a primary and over flow drain to accommodate the installation.  Please contact Zurn engineering for additional technical support for your application.​​
