Hydromechanical grease traps sit under or near sinks and use baffles and flow control to separate grease from water. They are common in small cafes, coffee shops and quick-service restaurants with limited space. We install units from Zurn, Watts, Schier and Endura sized by gallons per minute. Each install includes a flow control fitting and proper venting to keep the trap working as designed. These units need frequent cleaning, so we place them where staff can reach the lid easily.

We then install it during rough-in so it is ready for inspection. Getting the trap right early avoids expensive changes after the slab is poured. We also coordinate with the city's pretreatment staff when they require a review.

FVR Plumbing stands behind our work with a solid warranty on all grease trap installations. The specific warranty period will be outlined in your service agreement and usually covers parts and labor for a designated timeframe. Manufacturer warranties also apply to the grease trap unit itself.
The cleaning frequency for a new grease trap depends on its size, the volume of FOG produced by your kitchen, and local regulations in Dover. In most cases, grease traps require cleaning every 1 to 3 months. Regular cleaning is essential to maintain efficiency and prevent backups.
That depends on local rules and the trap type. Some programs require dish machines to discharge through the interceptor, while others restrict high-temperature discharge into certain units, so we confirm the requirement before we install.
Most food service businesses that cook, wash dishes or prepare food with fats, oils or grease are required to have one. Local pretreatment programs set the specific rules, and we can help you find out what applies to your site.
FVR Plumbing provides a warranty on our workmanship for all grease trap installations. Additionally, the grease trap unit itself will typically come with a manufacturer's warranty. We will provide you with all warranty details at the time of installation, giving you peace of mind.
