Commercial Grease Trap Line Service
A grease trap that backs up is almost always a plumbing line problem before it is a pump-out problem. Afford-A-Rooter checks the kitchen drain lines feeding the trap, clears blockages in the run, and tells you honestly whether the trap itself needs pumping.

Why does a grease trap back up between pumpings?
A trap that backs up before its scheduled pumping usually has a blockage in the line ahead of it, not a full trap. Grease congeals fastest in the pipe run closest to the sink or fryer drop, where the water cools first. We inspect and clear that run so the trap keeps working the way it is supposed to, and we tell you plainly if the trap itself is the problem instead.
- Slow drains at multiple kitchen fixtures often trace back to one blocked line, not the trap
- Odor near a floor drain can mean a dry trap seal rather than a full trap
- Cold weather makes grease solidify faster in exterior or unheated runs
Signs the kitchen lines need attention
- Sinks or floor drains draining slower than usual
- Gurgling from a floor drain when another fixture runs
- Grease odor near the trap access or floor drains
- A trap that fills back up faster than it used to
