Grease Trap Keeps Backing Up?
When a restaurant's grease trap keeps backing up, the trap is often not the whole problem. The lines running into and out of it coat with grease, and a trap that is overdue for pumping lets grease pass further down the line. Hummel Plumbing clears and hydro jets commercial kitchen lines in San Clemente, camera inspects them to find what keeps causing the backup, and repairs damaged sections, 24 hours a day, so a backup at closing time does not turn into a closure the next morning. Call (949) 505-9828.
Why Grease Traps Keep Backing Up
- The interceptor is full and overdue for pumping, so grease passes through into the line beyond it
- The line from the sinks and dish machine to the trap is coated with hardened grease
- The line leaving the trap is choked with grease that got past it
- A cracked or settled section of line where grease collects and builds
More than one of these is often at work at the same time, which is why pumping the trap without clearing the lines, or clearing the lines while the trap stays full, just resets the clock.
What We Do About It
We clear the backup first so the kitchen can run. Then we hydro jet the lines, which scours grease off the pipe wall instead of punching a hole through it, and run a camera to see whether any section is cracked, offset, or holding water. Damaged sections get repaired.
Restaurant drain lines take a beating from grease and daily volume, and hydro jetting on a schedule beats an emergency closure on a Saturday night. We can look at your line and recommend a jetting schedule based on what is actually building up in it.

What Customers Say
5.0 stars across 140+ Google reviews.
As a retired plumbing contractor, I'd like to think that I can tell a good plumber, hard worker, and honest man after watching him work. I'm getting a little long in the tooth (and sore in the back) to do much of my own plumbing anymore and I call Jon when I need plumbing help. I have also referred him to my neighbors, who report that they have been very happy with him.
