Your Step-by-Step Septic System Repair Guide

If you’ve ever had a septic problem, you know it’s not the kind of issue you can ignore. One day everything’s fine, the next day you’re dealing with slow drains, funky smells, or even sewage backing up where it doesn’t belong. Yikes.

The good news? With the right game plan, and the right crew, septic repairs don’t have to be a nightmare. Around Sebastopol, folks searching for septic service near me in Sebastopol are usually looking for fast, honest, no-BS help. That’s exactly what we do at L.J. Construction, and we’ve been doing it since 1966.

This guide is meant to walk you through the whole process, from the first inspection to the final check. We’ll also cover how long repairs usually take (because let’s be real, nobody likes their yard dug up for long) and give you some simple tips to keep your system running smooth for years.

TL;DR (Quick Version for the Busy Folks)

  • Repairs start with an inspection, then diagnosis, then fixing the issue, whether it’s a clog, broken pipe, or drain field problem.
  • Some jobs take just a couple of hours; bigger ones can stretch out to a few days.
  • Preventive care (regular pumping, smart water use, inspections) saves you big money down the road.
  • If you’re in Sebastopol and googling septic service near me in Sebastopol, go with a licensed, local team that knows the soil, the rules, and the best way to protect your property.

Step 1: The Inspection – Finding Out What’s Really Going On

Think of this step like going to the doctor. Your septic system shows “symptoms,” but you won’t know the real problem until someone takes a closer look.

We’ll usually:

  • Pop open the tank to check for cracks or leaks.
  • Run water through the system to see if there’s a flow issue.
  • Walk the drain field to spot soggy patches or foul odors.


A lot of times, what feels like a disaster (like sewage backing up in your shower) might just be a full tank or a clogged line. Other times, it’s more serious. That’s why this step matters, guessing is a recipe for wasted time and money.

Step 2: Choosing the Right Fix

Once we know what’s wrong, it’s time to figure out how to fix it. Here’s the short list of the usual suspects:

  • Tank pumping – Pretty straightforward. If it’s full, we pump it.
  • Pipe repair – If a line cracks or clogs, we dig it up and replace the bad section.
  • Drain field fixes – When the ground is oversaturated or clogged, we may need to clean, rest, or even replace part of the field.
  • Tank repair or replacement – If the tank itself is cracked or leaking, patching may work, but sometimes replacement is the only option.


Every fix is a little different, and the right choice depends on your system’s age, size, and condition.

Step 3: Prepping the Job Site

This part’s all about setting the stage. Before we dig, we mark utilities, bring in equipment, and make sure we can get to the problem without tearing up your whole yard.

At L.J. Construction, we’ve always taken pride in being as “least disruptive to property” as possible. Translation: we know your yard is more than dirt, it’s where your kids play, where you host barbecues, where your dog digs holes you swear you’ll fill someday. We treat it with respect.

Step 4: The Repair Work

Here’s where the rubber meets the road. Depending on what we’re dealing with, repairs can take:

  • A few hours: Pumping or clearing a clogged pipe.
  • A day or two: Replacing a broken pipe section or making small tank repairs.
  • Several days: Replacing a whole drain field or installing a brand-new tank.


We’ve got nearly 60 years of experience behind us, so we’ve gotten pretty efficient. Still, some jobs just take time, you don’t want us rushing when it comes to keeping sewage where it belongs.

Step 5: Testing and Cleanup

After repairs, we always test the system. That means running water through it, checking for leaks, and making sure everything is flowing exactly like it should. Once we’re happy, we tidy up the site so you’re not left with a giant mess.

How to Keep Your Septic System Happy (a.k.a. Preventing Breakdowns)

Let’s be honest: septic repairs aren’t cheap, and they aren’t fun. The best thing you can do is avoid needing repairs in the first place. Here’s how:

  1. Pump it regularly – Every 3–5 years, depending on household size and usage. Think of it like an oil change for your house.
  2. Don’t flush garbage – Grease, wipes, cat litter, and chemicals are septic killers. If it’s not waste or toilet paper, don’t flush it.
  3. Spread out laundry and showers – Too much water all at once can flood the system.
  4. Protect your drain field – No cars, no heavy structures, and no big-rooted trees on top of it.
  5. Get inspections – A yearly check can catch small issues before they snowball into expensive repairs.

Why Local Matters

If you’ve ever searched septic service near me in Sebastopol, you know you’ve got options. But here’s the thing: septic systems aren’t one-size-fits-all. Soil conditions in Sebastopol aren’t the same as in, say, Santa Rosa. Local codes, groundwater levels, even the way properties are laid out, all of that plays a role.

That’s why choosing a local, licensed, insured company matters. At L.J. Construction, we’ve been working on systems in this community for generations. We know what works here because we’ve tested it, repaired it, and replaced it, thousands of times over.
