Main Line and Sewer Drainage in Kennewick, WA
When several fixtures back up at once, the problem is usually in the main line to the city sewer or septic. Tree roots from mature shade trees and shrubs find their way into older clay and cast iron laterals. We clear the main through a cleanout and inspect it with a camera so you can see breaks, bellies or root intrusion. Repair options include spot repairs, lining or replacement.

Sewer Camera Inspection in Kennewick, WA
When you have recurring drain problems, a sewer camera inspection is the best next step. We insert a flexible, waterproof camera into your pipes to visually diagnose issues like cracks, breaks, root intrusion, or significant blockages. This no-dig method allows for precise problem identification, saving you time and money on unnecessary digging.
Storm Drain & French Drain Installation in Kennewick, WA
Sudden, heavy downpours make proper storm drainage essential. Eastern Washington deals more with drought and heat, while spring snowmelt can still raise creeks and groundwater in low areas. We design and install effective storm drain and French drain systems in Kennewick, WA to divert excess water away from your foundation, preventing erosion and water damage. These systems are essential for managing runoff on properties with poor grading or soil that swells when wet, protecting your home's structural integrity.
Hydro-Jetting Services in Kennewick
For the toughest clogs and stubborn buildup, our hydro-jetting service in Kennewick is a highly effective solution. This method uses high-pressure water streams to scour the interior of your pipes, removing years of accumulated grease, scale, and debris. It's an excellent preventive maintenance tool, especially for commercial kitchens or homes with persistent scale problems, leaving your pipes clean and free-flowing.
Channel and Trench Drains in Kennewick, WA
Driveways and patios that slope toward the house can send storm runoff straight into a garage or under a door. A channel drain with a grate catches that sheet flow before it reaches the building. We use durable polymer or concrete channels from brands like NDS and set them flush with the surface. The channel ties into solid pipe that carries the water to a safe outlet.
French Drain Installation in Kennewick
A French drain is a gravel-filled trench with perforated pipe that collects water and carries it away from problem areas. It works well along foundations, behind retaining walls and in low spots that hold water after storms. We wrap the gravel in filter fabric so fine soil does not clog the system. The drain is sloped to an outlet, dry well or approved discharge point.
Outdoor & Storm Drain Cleaning in Kennewick
Outdoor drains, including storm drains and area drains, are important for preventing water accumulation around your property, especially during heavy rainfall. We clear debris, leaves, and sediment from these systems to ensure proper water runoff and protect your foundation from potential water damage. Regular cleaning can prevent expensive landscape and structural issues.

Sewer Line Repair & Replacement in Kennewick, WA
Issues with your main sewer line can lead to significant problems, including foul odors and widespread backups. Our sewer line services in Kennewick, WA begin with thorough camera inspections to accurately locate breaks, cracks, or tree root intrusions. We offer both trenchless repair options, like pipe lining or bursting, and traditional excavation methods, depending on the severity and location of the damage, minimizing disruption to your property.

Frequently Asked Questions About Drainage Services in Kennewick
The cost of drainage services in Kennewick, WA varies a lot depending on the type and severity of the issue. A basic drain cleaning might range from $150 to $400, while more complex issues like main sewer line repairs or hydro-jetting could be anywhere from $500 to several thousand dollars. We always provide a clear, upfront estimate before starting any work.
Yes, major sewer line repairs or replacements in Kennewick, WA typically require plumbing permits to ensure the work complies with local building codes. FHN Plumbing handles all required permitting processes, ensuring your project is fully compliant and passes all required inspections.
Yes, heavy runoff that pools against the house can make soil swell and stress the foundation. Steep slopes and wet soils can shift over time, which stresses buried sewer and water lines and sometimes separates joints. It can also erode soil under walkways and patios. Directing roof and surface water away from the foundation helps protect the structure.
Common signs include slow drains, gurgling sounds from pipes or toilets, unpleasant odors coming from drains, water backing up into sinks or showers, and multiple fixtures draining slowly at once. If you notice any of these, it's time to call a professional.
Tree roots are attracted to the water and nutrients inside sewer pipes. Small cracks or loose joints in the pipes, often found in older systems, allow roots to enter and grow, eventually creating significant blockages. This is a frequent issue in Washington neighborhoods where many homes have mature trees.
Minor drain cleaning typically does not require a permit. However, significant drain repairs, such as replacing a section of a main sewer line or extensive re-piping, usually require a plumbing permit from the local Kennewick building department to ensure compliance with local codes. Our team handles all required permitting.
We use professional equipment from trusted brands like Spartan Tool, RIDGID, and Gorlitz for our drain cleaning and inspection services. These brands are known for their reliability and effectiveness in tackling even the toughest clogs, ensuring a high-quality repair.
A French drain collects water that soaks into soil and is best along foundations and low areas. A channel drain catches water flowing across hard surfaces like driveways and patios. Plenty of properties benefit from both.
