Why does my cast iron drain keep clogging up?

Older sewer systems made of cast iron often experience frequent clogging because the interior of the pipes becomes rough over time. Even before the cast iron starts to leak, this deterioration process begins, creating rough surfaces inside the pipes that provide more surface area for particulates and grease to accumulate. As a result, these rough surfaces become more prone to blockages.

How do old floor drains work?

The concrete floor around the drain is designed to slope inward, allowing water to gather in the drain and be directed away from the house. Nowadays, floor drains typically guide the water to a collection pit. From there, a sump pump is used to pump the water out to the surface of the property.

How do you plug an old floor drain?

You can use test balls, twist plugs, or pressure plugs to effectively seal floor drains. However, it’s important to note that these options will prevent water from flowing in either direction. In case these specialized plugs are not accessible, you can use a flexible rubber ball that is slightly larger than the pipe diameter as a temporary solution. Just remember to secure it in place by bracing it appropriately.

How do you install a cast iron floor drain?

To install the pipe, start by applying soapy water to ease the insertion. Then, adjust the pipe to the desired height. The highest position is 12 inches, and you can add a sleeve extension if needed. Twist the outer sleeve to the left or right until it locks into the notches. Once in place, secure the outer sleeve by nailing it in four recommended places. Finally, nail the pipe to form the deck, and ensure the floor drain is embedded in concrete.
