Switch Blocked Outlet 5.10 Inch Water Column Normally Closed [sku] from Water Heater Parts [brand] prevents the backflow of water into a hot water heater.

The Switch Blocked Outlet is made of durable materials and is designed to withstand the high temperatures and pressures of a hot water heater. It is also easy to install and maintain.
