Hire Sacramento Greasetrap for larger or outdoor interceptors.

Why Grease Trap Maintenance Matters for Homeowners

What a Greasetrap Does and Why It Fails

A grease trap separates fats, oils, grease (FOG), and other substances from wastewater so grease does not enter your household plumbing or the sewer system. As wastewater enters the trap, FOG cools and begins to solidify, causing it to rise to the surface.

This process of separating FOG from water results in the accumulation of sludge at the bottom of the trap, which must be removed during cleaning. Over time, grease solidifies, clogs inlet/outlet baffles, and reduces capacity. Without regular grease trap maintenance you face slow drains, backups, bad smells, and plumbing repairs.

Health, Plumbing, and Environmental Risks

A neglected trap can cause a blockage in your plumbing system, attracts bacteria and pests, produces persistent odors, and can spill over into drains. Environmentally, grease in the sewer can create blockages and contamination. Keeping the trap clean protects your home and the neighborhood system. Adhering to local disposal regulations is essential to ensure that grease and waste are properly disposed of and do not harm the environment.

When To Clean: Greasetrap Maintenance Schedule and Inspection Signs

Recommended schedule (residential): Clean out grease trap every 1–3 months depending on cooking volume. Heavy frying households should check monthly. Use the grease trap cleaning schedule below. Regular inspections help determine whether the grease trap can be cleaned in-house or if professional service is needed.

Quick Inspection Checklist (look monthly)

Grease layer > 25% of trap depth → clean now.
Slow draining sinks or gurgling drains → inspect.
Foul odors or visible solids → clean out immediately.
Visible cracks or damaged baffles → call a pro.
Traps should be checked regularly to maintain optimal performance.

Keep a grease trap maintenance log: date, person, amount removed (estimate), and any notes. Logs help track patterns and can be useful if you sell the house or need to show good maintenance.

Full Step-By-Step: Cleaning a Greasetrap (Tools, Safety, Process)

Safety Gear and Prep (Pro Tips)

Always: gloves, goggles, mask, and sturdy footwear. Work in a ventilated area and have absorbent materials and sealable containers on hand. Pro tip: place plastic sheeting around the work area to protect floors, and ensure the area around the grease trap, including the floor, is protected and accessible.

Tools & supplies

Heavy-duty gloves and goggles.
Sturdy scoop or small shovel.
Sealable rigid containers or buckets with lids.
Brushes and scrubbers, hot water, mild degreaser or enzyme cleaner.
Wrench (for removing tightly secured lids).
Steel pot scrubber (for thorough cleaning of internal components).
Plastic bags, absorbent material (cat litter), and rags.
Optional: hand pump for liquids or hose for rinsing.

Step 1 — Accessing and Inspecting the Trap

Turn off any nearby equipment.
Remove the trap cover and slowly grease can be under pressure.
Inspect for obvious damage, large solids, and grease depth. Check the tank components, including baffles, lid, and walls, to ensure the tank is functioning optimally.

Step 2 — Removing Solids and Grease (DIY method)

Use a scoop to remove floating grease and food solids. Remove any sludge and solid debris that may have accumulated at the bottom.
Place waste into sealable containers. All greases and debris should be collected for proper disposal. Watch-Out: never pour grease down the sink or into storm drains.
For heavy solid layers, scrape gently; avoid damaging baffles.

Step 3 — Pumping/Managing Liquids and Disposal (Watch-Outs)

Remove liquid waste with a pump or by carefully bucket-bailing into a secure container.
Check local Sacramento disposal rules many areas require that grease waste go to licensed waste handlers or specific landfill streams. If you’re unsure, call Sacramento Greasetrap to handle disposal.

Note: Grease waste should be properly disposed of according to local regulations. Never throw grease or solids in the trash unless they have been solidified, for example by mixing with kitty litter, to prevent leaks and contamination. Once solidified, the waste can be safely disposed of in the trash as permitted by local guidelines.

Watch-Out: Do not discharge concentrated FOG down the drain.

Step 4 — Cleaning, Rinsing, and Reassembly

Scrub internal surfaces with hot water and an enzyme-based cleaner to help break down residues. Use soap or dish soap and room temperature water to thoroughly clean all components, including the baffles, sides, and lid, ensuring removal of grease, odors, and residue.
Rinse with hot water. Flush the trap with room temperature water to ensure all residues are removed and proper flow is maintained.

After rinsing, use a wet/dry vacuum to provide suction and suck out any remaining water or debris for a thorough clean.

Reassemble all baffles, seals, and the lid. Tighten securely and test for leaks.

Step 5 — Documenting Your Greasetrap Maintenance Log

Record: date, time, person, amount removed, any repairs needed, and the next recommended service date. Adhering to local regulations and keeping the grease trap free of FOG, odors, and blockages is essential for compliance and optimal operation. Keep manifests if you use a licensed waste hauler.

DIY vs Professional Greasetrap Cleaning: Comparison and Cost Considerations

DIY is reasonable for small under-sink residential traps if you follow safety and disposal rules. Pros are recommended when:

Traps are large or buried outdoors.
