Grease Trap Cleaning and Repair

Grease Trap Cleaning, Maintenance and Repair is an important process in the operation of a grease trap / interceptor. Below is an overview and live project of a Grease Trap Repair.

What is a Grease Trap

A Grease Trap (also named grease capsule, grease converter, grease interceptor and seperator) is a tank which is designed to trap and collect fats, oils, grease, and solids (FOGS) before they flow out and enter a wastewater disposal system. Generally used commercial kitchens and restuarants they comprise boxes within the drainage run that flows between the sinks in a kitchen and the sewer system. The Grease Traps primary job is to contain the grease and solids before entering the sewer system which would cause blockages in the network. The grease trap once at its maximim capacity needs to be serviced and pump-out routinely, if this is not done correctly this can result in back-up of the sewer system and blockages in the commercial kitchen plumbing system.

Why grease trap blockages occur

Grease Trap Blockages generally happen when grease and solidified fat is trapped and builds up between the grease trap baffle walls to the extent where the grease cannot be contained in the interceptor. The grease will then flow out of the grease trap outlet and solidify, harden and cause blockages in the connected sewer system. 

Grease Trap Cleaning and Repair

Grease Trap cleaning and maintenance can be performed by a professional contractor.  If the walls of the Grease Trap and baffles are too worn and deteriorated the trap can be relined and repaired. Two of the best on market products that contractors can use to clean the Grease Trap and Reline the wall are Grease Grenade and Smooth Trowel.

Grease Grenade’s non-corrosive surfactant blend easily penetrates built-up grease and breaks down solid blockages. When repairing a grease trap the walls need to be cleaned effectively to allow for the epoxy mortar product to bond well to the surface. Just using high pressure water only will not effectively clean the wall and still leave a residue on the surface. Grease Grenade must be used in order to clean correctly.

Smooth Trowel is a high-strength epoxy mortar for structural concrete repair. Once the Grease Trap wall have been properly cleaned the smooth trowel epoxy mortar can be applied to the trap walls for a structural high build repair. 

Once the Grease Trap has been repaired the Grease grenade product can be used with a hydro jetter to pass through the inlet pipes which helps prevent the build up of grease.

A Successful Clean and Reline of a Grease Trap

Grease Trap was badly deteriorated and in need of some much needed love.

The Grease pit was cleaned using Pipe Magics Grease Grendade and then structurally repaired using the epoxy mortar product smooth trowel.
