What should I do today before the pro arrives?
Stop sending greasy water down the affected drain and avoid running more water through it. Continued flow can worsen the blockage and raise overflow risk. Arrange professional cleaning rather than trying to clear it yourself.
Does a commercial grease line need hydro-jetting?
Commercial-grade hydro jetting is required for grease buildup in many cases. A published 2026 schedule lists commercial grease-line hydro-jetting at about $650 to $2,250. Ask the pro which method they will use and why.
What should I check when hiring a pro?
Ask the pro for proof of licence and insurance before work begins. Confirm they can dispatch before your opening time. Missouri has no statewide plumbing code, so local plumbing codes and municipal FOG programs set grease-interceptor rules.
Why might the clog keep coming back?
Grease can accumulate and clog pipes repeatedly. Kansas City's cold season lasts about three months, so problems can recur through winter without regular maintenance. Repeated clogs can also point to a larger line issue, so ask the pro to inspect the sewer line.
What to do next
- Ask the pro for a quote that separates a standard trap cleaning from hydro-jetting, since the cost ranges differ.
- Request proof of licence and insurance before work starts, and ask whether they can dispatch before your opening time.
- Ask whether exposed lines or outdoor interceptors need insulation after the clog is cleared, since the first hard freeze in Kansas City is around November 11.
- Ask the pro to check your grease interceptor sizing against local plumbing code, which uses peak drain flow multiplied by a 30-minute retention time.
