A sewer line problem is one of those things that can go unnoticed for months before it turns into a real headache. Thompson Plumbing Heating & Air Conditioning has been helping Oceanside homeowners catch sewer issues early for over four decades, using video inspection technology to see exactly what’s happening underground without any guesswork. Our team knows what to look for and how local conditions affect the pipes running beneath your property.

Whether you’re dealing with slow drains, buying a new home, or just want peace of mind, a sewer inspection gives you a clear picture of your plumbing system’s condition. We walk you through everything we find in plain language, no confusing jargon, so you always know exactly where you stand and what your options are. Many homeowners wait until a backup happens before considering an inspection, but catching problems early almost always saves time, money, and stress down the road.

Jacob was fantastic to work with, as he was not pushy like the Anderson guy who used scare tactics, tried to upsell unnecessary add-ons, and even asked what our budget was. Jacob was very responsive and worked incredibly hard to accommodate our requests.

The installation was fast, just a day or two after the agreement was signed. The installation team was friendly, informative and skilled. They also discovered a leak in the vent seal and scheduled a roofer to take care of that. All in all this was a positive experience.

Ramon arrived right on time and was very professional. He knew exactly what needed to be done and explained it so I would understand why the old plumbing pipes were near the end of their life. He did a great job and was cheerful and very pleasant. I would highly recommend Thompson Plumbing and would definitely ask for Ramon again.

Called Thompson plumbing for an issue I had while changing out my shower valve. Thomas plumbing sent technician Jose Reyes within one hour. Jose promptly diagnosed the issue and gave me a reasonable quote. Once I accepted the quote he went to work and completed the job in a timely manner, Jose did a great job. Very satisfied

We had a great experience with Thompson Plumbing. Jose and Ignacio installed a tankless water heater, a whole house filter and replaced a whole bunch of old copper pipe. All around professionalism from booking the appointment to paying for the work. We now have a go to plumber here in Oceanside!

Signs It's Time for a Sewer Inspection

Sewer issues don’t always show up in obvious ways at first. Keep an eye out for these common warning signs.

  • Slow or gurgling drains
  • Recurring clogs in multiple fixtures
  • Sewage odors in the yard
  • Soggy or unusually green patches of lawn
  • Cracks in your foundation
  • Multiple drains backing up at once
  • A home older than 40 years

What Our Inspections Often Uncover

When we run a camera through a sewer line, we’re often able to spot problems long before they become emergencies. Tree root intrusion is one of the most common issues we find in Oceanside, especially in older neighborhoods with mature landscaping. Roots naturally seek out moisture, and even a tiny crack in a pipe can be enough for them to work their way in and cause a full blockage over time. Once roots take hold, they tend to grow quickly, and what starts as a minor obstruction can become a complete backup within months.

We also frequently find pipe corrosion and deterioration, particularly in homes with older clay or cast iron sewer lines. Coastal humidity and salt air can accelerate wear on certain materials, which means Oceanside homes sometimes show signs of aging in their pipes sooner than homes farther inland. Add in shifting soil from seasonal rain, and it’s easy to see why regular inspections matter here more than in some other regions. Soil that expands and contracts with changes in moisture can also put pressure on pipe joints, leading to gradual separation over time.

Beyond root intrusion and corrosion, our inspections often reveal pipe misalignment, bellied sections where waste collects rather than flows through, and blockages caused by grease or debris buildup. Catching these issues on camera means we can recommend the right fix the first time, rather than guessing based on symptoms alone. It also provides homeowners with documented proof of the pipe’s condition, which can be valuable during a home sale or an insurance claim. Having that documentation on hand often speeds up negotiations and removes uncertainty for both buyers and sellers. 

How Our Sewer Inspection Services Work

Our inspection process starts with a conversation about what you’re experiencing, whether that’s slow drains, odors, or just routine maintenance. From there, our technician feeds a high-resolution camera through your sewer line to get a real-time look at what’s happening inside the pipe. This lets us pinpoint the exact location and cause of any issue without first digging up your yard, saving both time and unnecessary expense.

Once the inspection is complete, we review the footage with you and explain what we found in terms that actually make sense. If there’s a problem, we’ll lay out your repair options along with honest pricing so you can make an informed decision without feeling rushed. For homeowners who just want a baseline check, we can also provide a full report on the condition of your line for future reference, which is especially useful for older homes or properties that haven’t been inspected in years.

Throughout the process, we treat your property with respect and keep things as clean and efficient as possible. There’s no need to worry about a mess or a long, drawn out appointment. Most inspections are completed in under an hour, giving you fast answers so you can plan your next steps with confidence. If follow-up work is needed, we’re happy to schedule it around your timeline rather than pressuring you into an immediate decision.
