What are Floor Drains? Floor drains are great for homeowners that experience standing water or flooding in the garage. However, they do require some upkeep and can lead to problems with pooling water if not used correctly or installed improperly. When it comes to the floor drain, there are two options for homeowners depending on the space available in your garage. The first option is a surface mount drain. This type of drain does not need to be mounted below the concrete and is often simply set atop it. The second option is an in-slab drain. This type of drain must be mounted below the concrete and is more difficult to set up. If you are interested in a floor drain, it is highly recommended that you hire a professional plumber to install the drainage pipe for you. Not only will this prevent any problems with construction or installation, but it will also help with the warranty of the floor drain. Types of Garage Floor Drains There are many different types of floor drains, but the two most common are surface mounted and in-slab. Surface Mounted Surface Mounted is a temporary installation and does not require any special plumbing knowledge to set up. This type of drain installs on top of the garage floor so it can be easily removed and cleaned when necessary. In-Slab In-slab must be installed underneath your concrete and is more difficult than your typical setting-on-top option discussed before. If you're thinking about installing an in-slab, it's important to hire a professional plumber for this job for both comfort and warranty. How Deep Is a Garage Floor Drain? On average, the depth of a garage floor drain is 12 inches to 14 inches from the surface of a garage floor up to the end of its pipe. Some garage floor drains can be deeper or shallower than that, depending on the age and manufacturer. Various factors can increase or decrease the depth of a garage floor drain. As an example, if you have concrete with 4 inches of concrete on top of the gravel, the depth of the drain wouldn't be 12 inches from the surface. In some cases, it may be beneficial to add more gravel or use a higher ratio of sand to cement to have the drain be deeper. Garage floor drains go under the garage floor and range from 8 inches to 3 feet in diameter with a grate cover over them [to prevent people from stepping into them]. They allow the water that gets on the surface of the garage floor to be drained and they also can provide access for maintenance and repair work. Who Needs a Garage Floor Drain? Many homeowners do not need a floor drain in their garage. If there is no chance of flooding in the garage (such as due to heavy rain or snowmelt) then a floor drain is not needed. If you do find yourself with water accumulation in the garage, then it may be time for you to look into installing a garage floor drain. A great way to determine if your garage needs a floor drain is to look for standing water accumulation.
