Our Top 5 Best Sewer Cleanout Covers

What's In This Guide?

      What Is a Sewer Cleanout Cover?

      A sewer cleanout cover is a cover or cap to the opening of your sewer line cleanout, which gives you access to the main sewer line for inspection, repair, or both. Many cleanouts are located outside near the water meter or against the house, but you will also find some in the floor.

      Most sewer cleanout plugs must fit a standard 4” cleanout size.

      To remove a sewer cleanout cover, you typically need a special tool. Covers aren’t made to be easy to remove since you don’t want to experience a leak if it gets loose. Some flat caps only require a screwdriver.

      Reasons to remove the cover generally include gaining cleanout access to run an auger or camera into your main sewer line to address a plumbing problem. If you’re lucky, you might be able to resolve a clog using only a plunger like this guy in the below video.

      Let’s be realistic. Main line clogs often require more than just a plunger, and a drain snake will be your tool of choice.

      What Are The Different Types of Sewer Cleanout Covers?

      Floor Cleanout Cover

      A floor cleanout cover covers the cleanout in your basement floor or garage floor. You can also find a floor cleanout outside. 

      When buying a floor cleanout cover, consider whether a vehicle may drive or park over it. Floor cleanout covers may benefits from strong material that can withstand a lot of weight. Furthermore, they may benefit from a flat shape. 

      Outside Cleanout Cover

      An outside cleanout cover covers a cleanout outside. You can often find them near the outside bib or the water meter. 

      Outside cleanout covers must be able to adhere to the elements in your climate.

      What Do You Look For In Choosing A Sewer Cleanout Cover?

      Material 

      One of the most important things you need to consider is the material of the cleanout cover. In most cases, you will find your sewer cleanout made from plastic or brass. Some will also have rubber components. 

      Plastic sewer cleanout covers don’t succumb to corrosion. However, they aren’t as strong as brass sewer cleanouts. Plastic cleanout covers tend to cost less than brass. 

      Appearance

      The primary function of a sewer cleanout cover is to cover the cleanout so that water doesn’t escape, or enter in when it rains. However, you can also use the cover to enhance the appearance of your home. (If you’re fancy like that.)

      Look for decorative cleanouts if you don’t mind paying a bit more for a square sewer cleanout cover or another decorative sewer cleanout cover.
