Grease Trap Installation: When Replacement Beats Repair
When a grease trap starts failing, the question is not just how to fix it — it is whether fixing it makes financial sense. A corroded, undersized, or cracked trap will keep costing you money until you address the root problem. Here is how to decide between repair and replacement.
When repair makes sense
Minor plumbing issues around a sound trap body — a stuck valve, a clogged inlet, a worn gasket — are worth repairing. If the trap itself is structurally sound and properly sized, fix the peripheral problem and move on.
When replacement is the better call
Replace the trap if the body is cracked, corroded, or undersized for your current kitchen volume. If repair costs exceed half the replacement cost, replacement is the smarter long-term investment.
An undersized trap will overflow no matter how often you pump it. Sizing it correctly during replacement prevents years of recurring problems.
Planning an installation
Trap sizing depends on fixture count, kitchen volume, and local code. Permits may be required depending on your municipality.
