How to Repair a Septic Tank In Sherborne

If you live in a house with a septic tank, it's likely that at some point you'll need to repair it. Whether it's a simple clog or something more serious like a broken pipe connection or cracked concrete, knowing how your septic tank works can help guide you through the repair process. In this article, we'll cover what to expect when repairing your septic tank and offer tips on how to make sure everything goes smoothly.

How to Repair a Septic Tank In Sherborne

Know your septic tank

  • Inspect the septic tank. Check to see if it is leaking, which could indicate that there are cracks or holes in the tank. This can be done by placing a tarp underneath the tank, then pouring water on top of it; any leaks will show up as discoloration within 30 minutes. If your septic tank is buried underground, you will not be able to use a trap, but you can inspect the ground surrounding it and look for signs of waterlogging or unexpected plant growth.

  • Determine if your septic system needs to be replaced or repaired. If you notice that your drains are clogged, this may be an indication that your septic system is not functioning properly, and that it may need replacement rather than repair (if possible). You can also test for leaks by putting food coloring in a container of water and adding it to your toilet bowl; if color appears in any part of your house within 30 minutes or so after flushing, then this indicates that there is likely some kind of leak occurring somewhere within your plumbing system (including possibly underground).

Inspect the tank and surrounding area

  • Inspect the tank and surrounding area.

  • Check for cracks or holes in the septic tank.

  • Look for signs of leaks around the drain field pipes that lead from your septic tank to your drain field. This is usually located near your home's foundation, beneath a layer of mulch or grass and dirt.

  • Check the lid on top of your septic tank for cracks or holes as well as any drain field pipes that are connected to it—this can be done by taking off its cover if necessary, which can only be done if you have enough space around it—by having an adult help you lift off the lid manually before checking both sides with a flashlight (if needed).

Identify common issues

If you notice any of the following issues, your septic tank is in need of some attention:

  • Leaking septic tank: A leaking septic tank could be caused by cracks or holes in the concrete or fiberglass shell. If water is flowing out of these areas, you should have them repaired immediately.

  • Septic tank backup: A backup occurs when solid waste becomes trapped inside a drain field and causes sewer pipe clogs. The only way to remove this buildup is by using a backhoe to dig up the drain field and remove it manually.

  • Sewer pipe clogs: Clogged pipes are another common issue with septic tanks. They're easy enough to fix—you'll just want to make sure no one else tries beforehand (see below).

Fix broken pipe connections

  • Inspect the tank for broken pipes and loose connections. Look for any leaks or signs that the pipe connections are damaged, like rust or exposed metal parts. If you find any damage, use a wrench to tighten these connections so that there is no longer a gap between them. This will prevent further seepage from occurring in these areas of your tank system and prevent sewage from leaking into other parts of your property or neighborhood.

  • Call a professional if you can't find the leak yourself—if you're having trouble locating it by yourself, don't hesitate to call in someone who knows what they're doing!

Repair cracks in a concrete septic tank

When your concrete septic tank has a crack, you'll need to repair it. You can use a concrete patching material (like those used on driveways or sidewalks) and apply the product to the crack. Let the patching material dry and then saltwater test the repaired area.

You may want to go through a local hardware store or home improvement store and see what they have in terms of concrete sealing supplies. A lot of times, these stores will have all sorts of things that you can use for this kind of project—from cleaners to fillers and everything else!

Repair a failing drain field

In some cases, a failing drain field can be repaired. If you have been experiencing slow-draining sinks and tubs, or if your washing machine is overflowing with water after use, then there may be a problem with your drain field.

When repairing a failing drain field:

  • You will need heavy equipment to lift the concrete slab and access the underground pipes. This is usually done by hiring contractors who work for septic tank companies like Pro Septic Tanks.

  • Once access has been gained to the drain lines and leach fields, you must remove any clogs that are causing a blockage in order for them to function properly once again.

Find the filter inlet pipe

To find the filter inlet pipe, look for the largest pipe coming out of your septic tank. It will be at the top of your tank and should have a small diameter—about 3 inches. The filter inlet pipe is attached to this larger main line via a fitting called a “tee” or “Y”.

Once you find it, simply follow it down into your drain field system until it reaches one of your filters. Remove that filter and clean up any mess inside before proceeding with backfilling and reinstalling everything else as needed.

Clean or replace the filter

To clean the filter, simply remove it and soak it in a sink or bucket filled with warm water. Let it soak for at least one hour, then rinse and dry it thoroughly with a cloth. Replace the filter after each cleaning (or more often if you have an extremely dirty tank).

If you need to replace your septic tank’s entire filtration system, there are several options available:

The better you know how your septic tank works, the easier it is to fix if it breaks down.

If you're looking for a way to save money on your septic tank, the best thing you can do is learn how it works.
