- Residential plumbing includes plumbing systems in homes and small units — like faucets, toilets, water heaters, and household leaks.
Commercial plumbing involves larger systems, compliance requirements, backflow certification, and heavy-use infrastructure for businesses, multifamily buildings, and property portfolios. We provide both.

Yes. We assist with fixture upgrades, piping changes, and complete plumbing work required for remodels and renovations.
Yes — Flow City Plumbing is fully licensed and insured, with over 125 years of combined technician experience.
We recommend seasonal maintenance like insulating pipes, checking water heaters, and clearing drains before heavy use periods — call us for a winter/holiday prep checklist.
Backflow prevention stops contaminated water from entering your clean water supply. It’s required when cross-connections (like irrigation systems) exist and must be tested yearly.
Our technicians evaluate sewer pipes using inspections to determine whether damage is localized (spot repair) or extensive (full replacement) before recommending the right solution.
Tankless models offer on-demand hot water, improved energy efficiency, and a smaller footprint compared to traditional tank systems — and we install both types.
We use mini cameras fed into your pipe system to visually inspect the interior for cracks, blockages, and root intrusion — providing accurate diagnosis without guesswork.
Call professional leak detection if water damage is suspected behind walls, under slabs, or if you can’t locate the source yourself — early detection saves time and money.
Signs include no hot water, inconsistent temperature, leaks around the tank, strange noises, or rust-colored water — call us for a professional assessment.
We recommend scheduling professional drain cleaning periodically (often yearly) to prevent buildup and backups — especially for high-use kitchens and older systems.
Low water pressure may result from clogs, corrosion, or hidden leaks. Our team diagnoses the reason and performs the necessary repair.
Whole-house repiping replaces old pipes throughout the home. The timeframe varies based on home size and complexity — our team will provide an estimate during inspection.
Yes — we offer trenchless sewer solutions that reduce yard disruption and speed up repairs compared to traditional excavation methods.
