Zurn Z130S and Z131S Siphonic Roof Drains

Learn how siphonic roof drains work and how your commercial space can benefit from installing a Zurn siphonic roof drain system. We’ll partner with you on a customized siphonic drain system that meets the needs of your building. Our systems result in more usable building space due to no-slope, horizontal piping that takes up less space running below the roof as compared to a gravity roof drain system. Zurn siphonic roof drain systems also utilize a smaller pipe diameter vs. gravity systems which translates to lower building costs. Learn more at zurn.com.
