Commercial Plumbing Services

When it comes to your business, plumbing issues don't keep business hours, and neither do we. Our commitment at Jim Dandy Sewer & Plumbing is to be the reliable partner your operation needs, which is why we offer 24/7 emergency service for commercial properties across the Seattle area. From a sudden sewer backup that threatens to shut down your restaurant to a broken water heater that stops production, our expert commercial team is always on call to provide fast, professional repairs and minimize your business downtime. We deliver a comprehensive suite of services designed specifically for the higher demands and complex systems found in commercial and industrial settings:

Commercial Drain Cleaning and Hydro Jetting:

Commercial drains, especially those in kitchens, public restrooms, and laundry facilities, experience a much higher volume of use and buildup of grease, sludge, and debris. We don't just use a standard snake; we utilize heavy-duty commercial equipment, including state-of-the-art Hydro Jetting technology. This process uses highly pressurized water to scour the entire interior of your pipes, completely removing stubborn blockages and years of accumulated scale, restoring your drain lines to their original flow capacity.

Commercial Water Heater Service, Repair, and Installation:

Your business relies on a constant, reliable supply of hot water, whether for hygiene, cooking, or industrial processes. We specialize in the installation, maintenance, and repair of large-capacity commercial water heaters and tankless systems. Our service includes preventative maintenance to maximize efficiency and spot potential failures, as well as rapid diagnostics and repair to ensure your operations never slow down due to a lack of hot water.

Sewer Line Inspection and Repair (Trenchless Technology):

The main sewer line is the backbone of your commercial property’s wastewater system. We use advanced camera inspection technology to accurately diagnose clogs, breaks, and root intrusion without invasive digging. When repairs are necessary, we often employ modern trenchless sewer repair methods like pipe lining or pipe bursting, which allow us to fix or replace major sections of your sewer line with minimal disruption and cost to your property, sidewalks, or landscaping.

Backflow Prevention:

To protect the public water supply from potential contamination originating within your facility, backflow prevention devices are essential and often legally mandated for commercial properties in Seattle. Our certified technicians specialize in the installation, and repair of all types of backflow prevention assemblies (like RPZ devices), ensuring your business remains compliant with local health codes and protecting the safety of your water system.

Commercial Fixture Repair/Replacement:

We handle all the essential fixtures your business relies on, from high-efficiency commercial toilets and urinals in public restrooms to heavy-duty industrial sinks, faucets, and garbage disposal units. Our team understands the need for durable, high-performance commercial-grade fixtures and is skilled in quickly diagnosing and repairing leaks, drips, clogs, and worn components to keep your facility fully functional.

Businesses That Rely on Our Commercial Plumbing Services

The truth is, any business that relies on working water, restrooms, or drainage needs the specialized expertise of a commercial plumber. Unlike residential systems, the plumbing in commercial properties handles high-volume usage, complex fixtures, and specialized equipment like grease traps, demanding a higher standard of maintenance and repair. At Jim Dandy Sewer & Plumbing, our team is specifically trained to serve the diverse needs of the Seattle business landscape.

Here are just some of the types of commercial properties we regularly serve:

Apartment Complexes and Multi-Unit Residences:

As a property manager or owner, your biggest challenge is high-volume, continuous use. We provide services tailored for multi-family buildings, including hydro-jetting to clear long, shared drain lines, repairing complex boiler systems for hot water, and quickly resolving unit-specific leaks to prevent damage to neighboring tenants. We are your partner in preventative maintenance to keep all your residents happy and your units fully functional.

Restaurants, Bars, and Commercial Kitchens:

No other industry faces as many plumbing demands as food service. We understand that a failure in a grease trap, a blocked floor drain, or a broken hot water system means an immediate shutdown. We offer specialized services like grease trap installation and maintenance, high-pressure jetting to break up food solids and oil buildup, and fast emergency response to get your kitchen back up to code and running quickly.

Office Buildings and Corporate Facilities:

From small-to-midsize businesses to major corporate campuses, plumbing must be reliable for both employee comfort and regulatory compliance. We handle the repair and installation of commercial-grade restrooms, water fountain maintenance, water main repairs, and ensure proper function of sump pumps and ejector pits in large facilities. We schedule our work to minimize disruption to your employees and daily operations.

Retail Stores and Shopping Centers:

Plumbing issues in a retail environment—especially public restrooms or burst pipes—can quickly lead to significant damage and lost sales. We provide expert repair and replacement of commercial fixtures and water lines, helping property managers maintain a clean, safe, and pleasant environment for their shoppers and tenants, often responding to urgent calls that require discretion and speed.

Industrial and Warehouse Facilities:

These properties often have the most demanding and specialized plumbing needs, including large-scale heating systems, industrial piping, and specialized drainage for process water. We have the heavy-duty equipment and certified expertise to work on large diameter pipes, high-capacity water heaters, and complex systems that keep your manufacturing, storage, or distribution operations flowing efficiently.
