      Why Do You Need A Drain Cleaner For The Main Line?

      The main line connects to either the septic tank or the city’s plumbing system. All water that exits your home goes through the sewer line, so a sewer drain clog will affect every drain in your home.

      Signs that you have a main line clog include:

      • Bad smells
      • Multiple slow drains
      • Gurgling coming from the toilet 

      A drain cleaner can help break up any clogs that develop before they become complete clogs. 

      Another way to prevent a main line clog involves being mindful of the things that you flush down your drain. Items like grease can build up over time. 

      Keep in mind that preventative maintenance is especially important for the main line since homeowners can’t access them easily. 

      After a clogged drain occurs, you may need to try a long drain snake or drain cleaning machine before calling for professional plumbing services. 

      What Are The Different Types Of Drain Cleaner For Main Line?

      Chemical Drain Cleaner 

      A chemical drain cleaner uses chemicals to dissolve the main sewer line clog using one of a variety of different chemicals. 

      Some of the chemicals found in chemical drain cleaners include:

      • Hydrochloric acid
      • Sodium Hydroxide 
      • Sulfuric acid
      • Lye
      • Trichlorobenzene

      Many of these chemicals can irritate the eyes and skin. The fumes can even be toxic, reducing the Air Quality Index (AQI) in your home. 

      The chemicals can also cause damage to your pipes by eating through them or causing corrosion. 

      However, they also provide the best results, making them the preferred choice for a serious clog. 

      Enzymatic Drain Cleaner 

      Enzymatic drain cleaners use natural materials, such as enzymes, bacteria, and probiotics, to eat through natural waste. 

      They are much safer for pipes and people, but they can’t eat through all materials that may create a clog. 

      While safer, not all enzymatic drain cleaners are organic or non-toxic.

      How Does Main Line Drain Cleaner Work?

      To clean the main sewer line, you will pour the drain cleaner down a toilet on the first floor of your home. Do not use a toilet if it also has a toilet clog. 

      You may need to mix the cleaner together with water in advance if you have a powder drain cleaner instead of a liquid drain cleaner. 

      Follow the instructions on your particular product to learn how much to pour down the toilet and how long you should expect to see results. In many cases, you need to pour boiling water down the drain with the cleaner to activate it. 

      What Do You Look For In The Best Drain Cleaner For Main Line?

      Safe For Pipes

      You need to pick a product that will keep your pipes safe. If you have plastic PVC pipes, some cleaners might be too harsh. Metal pipes may risk corrosion, so you need to find non-corrosive products. 

      Always be sure to use products exactly as instructed to ensure you don’t cause any damage. 

      Strength

      Some products work better as a part of your regular plumbing maintenance, while others have the power to dissolve more difficult clogs. 

      Always ensure that the product you buy has the capabilities to handle the clog by ensuring what materials it can break up (especially paper) and its strength.

      When To Get Professional Help With Your Main Drain Line?

      An especially tough clog in your sewer may not respond to a typical drain cleaner due to how far the clog developed in your plumbing system. 

      If a drain cleaner doesn’t work, try a drain auger.

      If the auger can’t do the trick, either, it’s time to call for a professional drain cleaning service, such as hydro jetting and sewer cleanout. 

      You also know you need a plumber if a complete clog occurs in your sewer line somewhere underneath the concrete slab or another inaccessible place. 

      After drain clearing, use a natural cleanser regularly and be mindful of the items you allow down the sewer drain. You can also install a grease trap to eliminate clogs in the future.
