Quick answer

Restaurant plumbing is uptime-critical and code-heavy: grease interceptors sized and maintained to code, backflow protection, floor drains, and commercial water heating — all kept running so a clog never stops service. Plumbing Outfitters handles food-service plumbing across Greater Austin, scheduled around your hours.

What's different about restaurant plumbing?

Food service has requirements a home never sees: a grease interceptor (grease trap) sized to your kitchen and pumped on schedule, robust floor drains, backflow protection on connections, high-demand commercial water heating, and fixtures that meet health-code standards. Above all, it's uptime-critical: a backed-up line during a dinner rush is lost revenue, not a minor inconvenience.

What does code require for a food-service kitchen?

Requirements vary by jurisdiction and the local health department, but they typically center on a properly sized and maintained grease interceptor (to keep grease out of the sewer), indirect waste / air gaps on certain equipment, backflow prevention, and adequate hot water. Because the specifics differ by city and change over time, confirm current requirements with your local building and health authorities — we build to the adopted code and coordinate inspections.

What shuts a restaurant kitchen down?

The big ones: a grease-clogged line (skipped interceptor maintenance is the usual cause), a failed health/code inspection over backflow or grease handling, and no-hot-water during service. Each is preventable with right-sized equipment and a maintenance rhythm. The most expensive mistake is treating a commercial kitchen like a big house — it isn't.

Frequently asked questions

How often does a restaurant grease trap need cleaning?
It depends on your interceptor size and volume of grease, and your local jurisdiction may set a required interval. The practical answer: on a schedule that prevents buildup and a clogged line — we'll help you set the right rhythm and hydro-jet lines when grease accumulates.
Can you fix a clogged restaurant line after hours?
We offer after-hours support for emergencies because a down line during or before service is lost revenue. For grease-heavy lines, hydro-jetting clears them far better than snaking.
