About Us

Stop paying expensive plumbing bills caused by food waste, trash, and large debris entering your floor drains and floor sinks. Drain-Net offers the Guardian Drain Lock — a durable stainless steel drain protection solution designed specifically for restaurants, commercial kitchens, food service facilities, supermarkets, and other high-traffic commercial environments.

In many facilities, employees and night cleaning crews remove drain covers and sweep food scraps, garbage, mop strings, and other debris directly into floor drains. Over time, this leads to clogged drain lines, emergency backups, foul odors, grease trap issues, and costly plumbing repairs.

The Guardian Drain Lock helps prevent these problems before they start. This tamper-resistant drain protection device installs in seconds and helps prevent unauthorized removal while still allowing water to flow properly through the drain system.

Benefits of Guardian Drain Lock

Reduce Plumbing and Maintenance Costs

Prevent drain line blockages caused by solid waste and reduce the need for emergency plumbing service, drain cleaning, and hydro jetting.

Protect Grease Traps and Interceptors

By stopping large debris from entering the drain system, the Guardian Drain Lock helps reduce grease trap solids buildup and may decrease the frequency of grease trap pumping and maintenance.

Improve Facility Operations

Avoid flooded floors, drain overflows, and unexpected plumbing emergencies that disrupt kitchen operations and employee productivity.

Help Maintain Wastewater Compliance

Reducing solids entering the wastewater system may help facilities lower the risk of municipal compliance violations and wastewater-related fines.

Prevent Expensive Pipe and Sewer Damage

Keep bags, rags, mop strings, food waste, utensils, and other debris out of drain lines where they can cause severe blockages and costly repairs.

Tamper-Resistant Drain Protection

The stainless steel locking design helps prevent staff, cleaners, or unauthorized personnel from removing the drain protection device.
