Quick Answer

Commercial hydro jetting uses high-pressure water (4,000–5,000+ PSI) to clear FOG (fats, oils, grease) buildup, scale, and debris from larger-diameter commercial drain lines — restaurant kitchens, floor drains, office buildings, and industrial properties. Grease accumulation in commercial kitchen lines is the leading cause of backups and health code violations in Macomb and Oakland County food service operations. Quarterly scheduling for high-volume kitchens. Biannual for offices. Emergency same-day available. Part of Bison’s Hydro Jetting and Commercial Plumbing services.

⚠ Health Code Compliance Risk

A Backed-Up Commercial Kitchen Drain Is a Health Code Violation

Under Michigan’s Food Law and local health department regulations, commercial food service operations are required to maintain functional drainage systems. A drain backup that causes wastewater to pool on kitchen floors, near food preparation surfaces, or in customer-accessible areas triggers mandatory health department inspection and can result in an immediate closure order. A documented recurring hydro jetting schedule demonstrates proactive food safety compliance — and prevents the emergency that makes compliance enforcement relevant.

Commercial vs. Residential Hydro Jetting — Why Higher PSI Matters

🏢 Commercial Grade

Commercial Hydro Jetting

Operating PSI4,000–5,000+ PSI — full power for large-diameter commercial lines
Pipe diameter4–12 inch commercial drain and sewer lines
Primary blockageFOG (fats, oils, grease) — high concentration from commercial cooking
GPM capacityHigher gallons per minute — necessary for larger pipe volume
SchedulingQuarterly, biannual, or annual based on business type and volume
🏠 Residential Grade

Residential Hydro Jetting

Operating PSI1,500–3,500 PSI — calibrated lower for older residential pipe
Pipe diameter1.5–4 inch residential drain lines
Primary blockageHousehold grease, hair, soap scum, and mineral scale
GPM capacityLower volume — appropriate for smaller residential pipe
SchedulingAnnual or biennial for pre-1980 cast-iron; as-needed for PVC

Industries and Property Types Served

🍳
Quarterly

Full-Service Restaurants

High cooking volume, multiple kitchen stations, and floor drains accumulate FOG rapidly. Quarterly jetting prevents the grease concentration that causes backups and municipal FOG discharge violations. Floor drain cleaning included.

🍔
Quarterly–Biannual

Fast Food & Quick Service

High-volume cooking in compact kitchen spaces with floor drains that handle heavy grease loads. Quarterly or biannual jetting depending on menu type and daily cover count. Service scheduled during off-hours to avoid operational disruption.

🏢
Biannual

Office Buildings

Office building floor drains, break room sinks, and restroom laterals accumulate scale and soap buildup over time. Biannual jetting maintains flow in commercial restroom drain lines and prevents slow-drain complaints from tenants.

🏭
Annual–Biannual

Retail & Mixed-Use

Shopping centers, strip malls, and mixed-use commercial properties with food tenants require more frequent jetting than those without. Main lateral cleaning and floor drain service prevents backup events that affect multiple tenants.

🏫
Biannual–Annual

Hotels & Event Venues

Commercial kitchen and banquet facility drain lines generate significant FOG loads during high-occupancy events. Biannual jetting timed before peak event seasons keeps large-capacity kitchen drain systems clear.

🔌
Annual

Industrial & Manufacturing

Industrial floor drains and process water drain lines in manufacturing facilities accumulate solids, oils, and scale that reduce flow capacity over time. Annual large-diameter main line jetting at 5,000+ PSI clears industrial drain infrastructure.

Recommended Jetting Schedules by Property Type

Commercial Hydro Jetting Scheduling Guide

Quarterly

Every 3 Months

Full-service restaurants, high-volume commercial kitchens, fast food operations with fryers. FOG accumulation at cooking volumes requires quarterly clearing to stay ahead of backup risk and municipal FOG compliance thresholds.

Biannual

Every 6 Months

Office buildings, low-to-medium volume food service, cafes, quick-service without fryers, hotels and event venues. Twice-yearly jetting maintains flow capacity and prevents slow-drain complaints from building occupants.

Annual

Once Per Year

Light commercial, retail without food tenants, industrial floor drains, and commercial properties where drainage demands are low. Annual jetting as preventive maintenance before issues develop.

Troy, Auburn Hills & Warren Commercial Corridors

🏢 High-Concentration Commercial Markets Served

Bison Plumbing serves commercial properties throughout Macomb and Oakland County’s densest commercial corridors — where restaurant and food service concentration makes drain maintenance a high-frequency operational requirement:

🏢 Troy — Somerset Collection & Big Beaver Corridor

Michigan’s largest retail concentration plus adjacent restaurant row and corporate campuses. High density of full-service restaurants, food halls, and hotel food service requiring quarterly kitchen drain service.

🏢 Auburn Hills — I-75 Commercial Corridor

Stellantis/Chrysler HQ campus, Oakland University, and I-75 commercial strip with significant food service density. Corporate campus cafeterias and restaurant corridor on Auburn Hills Drive generate high FOG volumes.

🏢 Warren — Van Dyke & Mound Industrial-Commercial

Warren’s dense industrial and commercial zones along Van Dyke and Mound Road corridors. Mix of manufacturing facilities with industrial floor drain needs and commercial food service along major corridors.

🏢 Birmingham & Royal Oak — Downtown Dining

Birmingham’s Old Woodward and Maple Road dining district plus Royal Oak’s Main Street restaurant corridor. Dense concentration of full-service restaurants in walkable downtown environments requiring regular kitchen drain maintenance.

Bison’s Commercial Hydro Jetting Process

1

Site Assessment — Map Drain Infrastructure and Set Schedule

For new commercial accounts, Bison performs a site assessment — mapping all drain lines, identifying grease interceptor locations, confirming pipe diameters, and assessing current accumulation level. This assessment sets the appropriate jetting schedule and establishes the baseline condition. For emergency calls, the assessment focuses on identifying the backup point and highest-priority lines to clear first.

2

Camera Confirmation — Locate Blockage and Assess Pipe Condition

Camera inspection confirms the accumulation location and severity before jetting begins — and identifies any structural pipe issues that would be aggravated by high-pressure jetting. For commercial kitchen lines with heavy FOG accumulation, camera footage also provides documentation of the pre-service condition for compliance records.

3

High-Pressure Commercial Jetting — Full Drain System

Commercial-grade jetting equipment at 4,000–5,000+ PSI runs each drain line from access point to the main lateral connection. FOG-cutting nozzle configurations are used for kitchen drain lines — the rotating fan spray penetrates and emulsifies grease deposits that standard nozzles cannot fully dislodge. Floor drains, branch lines, and the main lateral are all cleared in sequence.

4

Post-Jetting Camera Verification and Service Documentation

Post-jetting camera confirms full clearance of each drain line. Service documentation — including pre- and post-jetting camera footage and a service report — is provided for the property’s compliance records. For restaurants subject to health department inspection, Bison’s service documentation supports the drain maintenance compliance record. Recurring schedule is confirmed for the next service visit.

💡 Grease Interceptor + Hydro Jetting — the Full FOG Management System

Commercial hydro jetting of kitchen drain lines works best when combined with a maintained grease interceptor (grease trap). The interceptor captures FOG before it enters the municipal sewer system — but the lines between the kitchen and the interceptor still accumulate grease buildup that requires regular jetting to clear. Bison’s grease trap cleaning service combined with quarterly kitchen drain jetting provides comprehensive FOG management for high-volume food service operations.
