Repair versus replace, the real question
Most interceptor problems we see aren't sizing problems, they're hardware problems on a trap that was fine to begin with. A baffle that's cracked or come off its mounts lets grease bypass straight into the outlet line, no amount of pumping fixes that. A lid that's been driven over by a delivery truck one too many times crushes or cracks at the rim. A riser, the vertical section that brings the lid up to grade, can settle or shift after a parking lot repave, leaving the lid sitting an inch or two below where it should be. Every one of those is a repair, not a full tank replacement, and most get fixed in a single visit.
A full interceptor replacement is a different scope, usually triggered by a tank that's cracked below the waterline, corroded through on an old steel tank, or genuinely undersized for a kitchen that's grown past what it was built for. Kitchens expanding along Cinco Ranch Blvd or converting a smaller storefront into a full-service restaurant run into undersizing most often. That's a coordination job with your general contractor and the local permitting office, not a same-day fix.
Stated limit
We don't pour concrete or run new plumbing lines ourselves. Full interceptor installs get coordinated with your GC or plumber, we handle interceptor sizing recommendations, the interceptor unit itself, and startup service once it's set. We're not a general contractor and won't pretend to be one.
What we repair
- Baffle repair and replacement. Cracked, warped, or detached baffles get repaired in place when the tank itself is sound, or replaced if the damage is past a field fix.
- Lid and riser replacement. Crushed lids, undersized access openings, and settled or shifted risers get brought back to grade and to a spec that actually fits a service hose.
- Gasket and seal repair. A failed lid gasket lets rainwater and groundwater into the tank between visits, which throws off wetted-height readings and dilutes the manifest volume. We reseal or replace.
- Outlet and inlet pipe repair. Cracked or misaligned pipe connections at the tank itself, not the line running to the street.
New installation, sized right
New interceptor sizing follows the same logic city and county code uses: kitchen fixture count, seating capacity, and meal volume determine the minimum tank size, not just square footage. We work from your GC's plans or a site walk to recommend a size that clears code and gives you room before you're back to a 60-day cadence within a year of opening. Undersizing at install is the single most common reason a brand-new restaurant ends up on an emergency pump-out call within its first six months.
What makes this work harder
A tank buried deeper than standard because of a slab foundation or a prior remodel adds real excavation time to any repair that requires opening the ground around it. Older steel interceptors, mostly found in buildings from before fiberglass and polyethylene tanks became standard, corrode from the inside out in ways that aren't visible until the tank's opened. A riser that's shifted because of nearby parking lot settling sometimes points to a bigger paving problem than just the interceptor itself. And any repair on a tank still actively receiving wastewater needs a temporary bypass plan so the kitchen doesn't shut down mid-repair.
Price and duration
Baffle repair runs $225 to $450 for a straightforward field fix, $450 to $850 if the baffle needs full replacement. Lid and riser replacement runs $300 to $650 depending on depth and access. Gasket resealing runs $150 to $300. Most repairs finish in a single visit, 1 to 3 hours on site. New interceptor installation coordination, sizing, unit cost, and startup service, runs from roughly $1,800 for a small interior tank up to $8,500 or more for a large exterior interceptor sized for a banquet kitchen, and that's a multi-day project scheduled around your GC's timeline.
One thing worth stating plainly
We don't quote a full replacement until we've confirmed a repair genuinely won't work. A cracked baffle on an otherwise sound tank gets a baffle repair, not a sales pitch for a new interceptor.
