Odor Control and Trap Inspections in Portsmouth
Persistent odors usually point to a trap that is overdue, a missing seal or a damaged baffle. We inspect gaskets, lids and vent connections during every cleaning. If we find damage, we explain the issue and offer repair options. Sealing problems early keeps odors out of your kitchen and dining room. It also prevents grease from bypassing the trap entirely.

Outdoor Grease Interceptor Pumping in Portsmouth, NH
Large in-ground interceptors require a vacuum truck to fully pump out grease, water and settled solids. We open each compartment, pump it down and use high-pressure water to break up hardened grease on the walls. We inspect inlet and outlet tees, baffles and risers while the tank is empty. Warm weather can make grease odors stronger, so we also check lid seals. A complete pump-out restores full retention capacity.

Grease Trap Cleaning for Restaurants in Portsmouth, NH

Grease Line Jetting in Portsmouth
Grease that escapes the trap often coats the line between the kitchen and the interceptor or the sewer. We use hydro jetting to scour the inside of the pipe and remove hardened grease. Jetting is far more effective than a standard drain snake for grease buildup. We can run a camera afterward to confirm the line is clear. This prevents repeat backups and keeps your trap working as designed.

Grease Trap Hydro-Jetting in Portsmouth, NH
Sometimes, grease traps and their connecting lines develop tough blockages that standard pumping can't fully clear. Our hydro-jetting service uses high-pressure water streams to fully scour the interior of your grease trap and the associated drain lines. This removes hardened grease, scale, and other debris, restoring full flow and preventing recurring clogs in your Portsmouth, NH commercial property. It's an efficient way to reset your system.

Frequently Asked Questions About Grease Trap Cleaning in Portsmouth
The cost of grease trap cleaning in Portsmouth can range from $200 to $800 or more, depending on the size of the trap, its accessibility, and the level of FOG accumulation. Larger commercial traps requiring extensive pumping will be at the higher end. We provide clear, upfront pricing after an initial assessment.
Grease trap cleaning removes fats, oils, and grease (FOG), along with food solids, sediment, and wastewater. This material is often referred to as 'brown grease' and requires specialized handling and disposal to prevent environmental contamination.
Neglecting grease trap cleaning leads to severe FOG buildup, causing slow drains, complete plumbing blockages, foul odors, and potential sewage backups into your kitchen. It can also result in costly fines from health and environmental agencies in Portsmouth, NH.
The terms are often used interchangeably, but 'grease interceptor' typically refers to larger, outdoor units with capacities over 500 gallons, while 'grease trap' usually describes smaller, indoor units under 100 gallons, such as under-sink models. Both serve the same function of separating FOG from wastewater.
While cleaning services don't typically come with a 'warranty' in the traditional sense, FVR Plumbing guarantees the quality and effectiveness of our work. If you experience issues directly related to our cleaning within a reasonable timeframe, we will address them promptly. We stand by our professional standards.
Slow sink drains, foul odors, grease on the water surface near the outlet and backups from floor drains are common signs. If you notice any of these, schedule a cleaning right away.
The duration of a grease trap cleaning can vary, but most standard commercial cleanings take between 1 to 3 hours. Larger outdoor interceptors or traps with significant buildup may take longer. We aim to complete the service quickly to minimize disruption to your business operations in Portsmouth.
The cleaning frequency depends heavily on your business's FOG output and the size of your trap. Most restaurants require cleaning every 1 to 3 months, while high-volume establishments might need it monthly. Local health codes in Portsmouth might also specify minimum frequencies.
