The cleaning frequency for a new grease trap depends on its size, the volume of FOG produced by your kitchen, and local regulations in Manchester. Typically, grease traps require cleaning every 1 to 3 months. Regular cleaning is essential to maintain efficiency and prevent backups.
Indoor traps should be close to the fixtures they serve and easy to open for cleaning. Outdoor interceptors are typically placed where a pump truck can reach them without blocking customer traffic.
