Your septic system quietly handles all the wastewater leaving your property — until it doesn’t. Sullivan Plumbing repairs, maintains, and installs septic systems across Union County, with years of hands-on experience in the systems common to our rural properties.
Septic System Installation
Installing a septic system is a job you want done right the first time. We have experience installing a range of systems — conventional, pressure distribution, aerobic treatment, mound, and sand-lined — and we’ll help you choose the one that fits your property, soil, and household before any work begins.
Septic Repair & Maintenance
When your system has a problem, you want a local team you can rely on. We repair and maintain septic systems from the tank itself to the drain lines and components — clogged filters, sediment buildup, damaged or clogged drain lines, overflow, cracked tanks, damaged baffles, and aerated-system repairs. When a failure causes a backup, we also handle water and sewage removal as part of the fix. Regular maintenance prevents most expensive septic repairs and saves you money over the life of the system.
Signs of a septic problem
Slow drains throughout the house, sewage odors, wet or unusually green patches over the drain field, gurgling, or backups. Catch these early — a backed-up system can cost thousands.
