Overview
Grease traps stop fats, oils and grease (FOG) entering drains and sewers. For home or small commercial kitchens you want a compact, reliable interceptor that fits under the sink and is easy to empty and maintain. These VEVOR models are carbon steel, side-inlet designs intended for simple installation under a sink or in a service cupboard.
The most important factors are capacity (how much grease it holds), flow rate (how quickly it can accept water without backing up) and the physical footprint to ensure it fits your cabinet. Heavier-duty kitchens will need the larger capacity and higher GPM rating; occasional home cooking can work fine with the smaller unit.
All three share similar construction and inlet/outlet diameters, so you’ll see the main practical differences are internal volume, weight and dimensions. That makes this set easy to compare for buyers who know their expected usage and available space.
Check local regulations: some councils and water authorities require specific certified interceptors for commercial premises. Also confirm installation parts, warranty and any required adaptors with the seller before buying.

Buying guide
Decide on capacity by estimating daily greasy discharge: light home use can manage a small 8 lb interceptor, while busy cafés and small restaurants should consider 30–40 lb units. Measure the cabinet or space where the trap will sit and compare dimensions — under-sink plumbing and waste pipe sizing (inlet/outlet) must match. Think about maintenance: larger traps need emptying less often but are heavier to lift. Finally, check local plumbing codes; some areas require certified commercial grease interceptors and regular professional pump-out schedules.
FAQs
How often should I empty a grease trap?
Emptying depends on usage. Light domestic use might be monthly, while busy commercial kitchens may need weekly or more frequent emptying. Inspect the trap regularly and follow local regulations.
Our recommended choice
For most small commercial kitchens and busy home cooks the 40 lb VEVOR model balances capacity, flow rate and value. It handles higher volumes and reduces emptying frequency compared with the smaller units, making it the most practical all-round option.
