How often should floor drains in commercial kitchens be cleaned?

Floor drains in commercial kitchens should be cleaned weekly at minimum, and some high-volume operations benefit from daily drain maintenance. The trap must be filled with water regularly to prevent sewer gas entry. Floor drain covers and strainers should be cleaned and inspected at each cleaning to ensure they are intact and not allowing debris to enter the drain.

What causes commercial drain backups in Ontario businesses?

The most common causes of commercial drain backups are grease and fat buildup (especially in food service), root intrusion from trees into exterior sewer lines, debris accumulation due to missing or damaged strainers, scale buildup in older pipes, and cross-connections or improper use of floor drains (disposing of solids that should go to waste bins).

How often should a grease interceptor be cleaned in Ontario?

In Ontario, most municipalities require grease interceptors to be cleaned before they reach 25% capacity with fats, oils, and greases (FOG) — which in many restaurant applications means cleaning every 30–90 days. Some municipalities set specific minimum cleaning frequencies in their sewer-use bylaws. Keep records of all grease interceptor service, including manifests from certified waste haulers.

What is hydro-jetting and when is it needed for commercial drains?

Hydro-jetting uses high-pressure water (typically 2,000–4,000 PSI) to scour the interior walls of drain pipes, removing grease, scale, roots, and debris. It is more thorough than drain snaking and is recommended for annual maintenance of grease-laden drain lines or any time inspection reveals significant buildup. Unlike snaking, which punches a hole through a blockage, hydro-jetting cleans the full pipe circumference.

Can commercial drain problems affect my municipal compliance in Ontario?

Yes. Ontario municipalities regulate what businesses discharge to the sewer under their Sewer Use Bylaws. Excessive grease discharge can result in fines, required retrofits, or a compliance order. Restaurants and food processors are most commonly affected, but any business that discharges regulated substances — including some industrial fluids — must comply with local sewer-use requirements.

What is a drain maintenance schedule for a commercial office building in Ontario?

A commercial office building drain maintenance program typically includes: monthly inspection and cleaning of floor drain traps, quarterly inspection of building cleanouts, annual hydro-jetting of horizontal drain runs, annual camera inspection of the building drain and main sewer lateral, and immediate service for any drainage slowdowns before full blockages develop.

Commercial Drain Maintenance: Prevent Costly Backups

Q: How do I know if my commercial drains need jetting or just snaking?

Drain snaking (augering) is typically used to clear an active blockage or remove a specific obstruction. Hydro-jetting is more appropriate for thorough annual maintenance, grease line cleaning, or when camera inspection reveals significant buildup on pipe walls. A plumbing contractor can recommend the right approach after assessing the drain condition.

Q: Who is responsible for drain maintenance in a commercial leased space in Ontario?

Drain maintenance responsibility is generally set by the lease. In most Ontario commercial leases, the tenant is responsible for drain cleaning and maintenance within their demised space. The landlord typically maintains the shared building drain, main sewer lateral, and any shared equipment such as a building-wide grease interceptor. Review your specific lease terms.

Floor drains in commercial kitchens should be cleaned weekly at minimum. High-volume operations benefit from daily drain maintenance. The trap must be kept full of water to prevent sewer gas entry, and strainers should be cleaned and inspected at each cleaning.

The most common causes are grease and fat buildup (especially in food service), root intrusion into older sewer lines, debris accumulation from missing strainers, scale buildup in older pipes, and improper disposal of solids down drains.

Most Ontario municipalities require cleaning before the interceptor reaches 25% capacity with FOG — typically every 30–90 days for restaurants. Keep records of all cleanings from certified waste haulers for at least three years.
