Drain and Sewer Pipe Leak Repair in Federal Way, WA
Cast iron drain stacks in older homes crack and scale with age, and plastic joints can separate if a line was poorly supported. These leaks usually show up only when an upstairs fixture runs. We run water through each drain while watching the basement, then confirm the crack with a camera. Repairs range from a single section swap to replacing an entire stack with PVC or ABS.
Sump Pump Repair and Installation in Federal Way, WA
Many basements rely on a sump pit to handle storm runoff and groundwater. River flooding and saturated ground can push water back through sewer lines, so backwater valves and sump pumps are worth considering. Pumps from brands like Zoeller, Liberty and Wayne fail most often from a stuck float or a burned-out motor after sitting idle for months. We repair or replace the pump, check the check valve and route the discharge well away from the foundation. A battery backup is worth considering because big storms often knock out power.
Floor Drain and Backwater Valve Repair in Federal Way
A basement floor drain that backs up during heavy use or a storm typically points to a blockage or a failed trap. We clear the drain, check the line to the main sewer and replace cracked traps and covers. Installing a backwater valve stops sewage from pushing back into the basement if the main line surcharges. We set the valve where it can be serviced without trouble.
Water Heater and Appliance Leak Repair in Federal Way, WA
Water heaters, softeners and laundry machines are often installed in basements, and their leaks pool fast. A dripping T&P valve, a corroded tank bottom or a split washer hose are common culprits. We repair or replace the failed part and install drain pans and leak sensors to catch future problems early. If a tank has rusted through, we can replace it the same day in most situations.
Hydrostatic Pressure Management in Federal Way, WA
Heavy rain can lead to significant hydrostatic pressure against basement walls, forcing water through concrete. River flooding and soaked ground can push water back through sewer lines, so backwater valves and sump pumps are worth considering. FHN Plumbing installs interior and exterior drainage systems, including French drains and weeping tile systems, to relieve this pressure. We also install sump pump systems to efficiently remove collected water, keeping your basement dry.
Exterior Waterproofing Solutions in Federal Way, WA
For comprehensive basement leak prevention, exterior waterproofing involves excavating around your foundation and applying waterproof membranes or coatings. This creates a strong barrier against moisture intrusion from the outside. While more involved, this method offers superior long-term protection against water damage, especially for older homes in Federal Way.

Sump Pump Installation and Repair in Federal Way
A properly functioning sump pump is crucial for preventing basement flooding, especially during heavy downpours. FHN Plumbing provides professional sump pump installation, repair, and maintenance services. We ensure your pump is correctly sized and installed to handle the water volume, giving you peace of mind.
