Common Problems Associated With Grease Trap

Grease trap is an integral component of any commercial kitchen, responsible for removing fats, oils, and grease from the wastewater. A commercial kitchen running for a long time knows well that these FOG removing units need a good care at a regular pace. But if you are new in this field and come across some untoward condition like slow working or clogged grease trap, you should know that’s a serious grease trap problem. Because that can lead to health code violations, and unsanitary conditions while seriously interfering with your daily business operations – even according to experts.

So, it is better to learn some common grease trap problems and the solution to tackle them on-time.

Importance Of Grease Traps

Well, grease traps are used for commercial as well as for residential purpose to separate solid waste and FOG from wastewater before it runs down through pipelines and reaches the municipal sewage system.

Grease traps are installed in between the drain and the sewer system. So when the wastewater is thrown down the sink, it enters the trap and begins to cool. This allows the grease in the liquid to rise at the surface of the water and get harder. Simultaneously, the heavier solid waste particles and debris sink at the bottom of the trap. Hence, the middle layer (wastewater) is cleaned and allowed to flow down into the municipal sewer system.

What Are The General Grease Trap Problems?

With the passage of time, many problems get associated with grease trap and hence result in rotten smell or blockage in pipelines. The general problem associated with grease trap include:

Clog in Crossover

A grease trap consists of two compartments. The first compartment aids in separation of the solids and liquids while the second compartment supports the release of waste into the sewers. Now, when the FOG or debris builds up in the crossover line present in between the two compartments, it leads to clogging in the crossover line. Eventually, the liquid level in the first compartment will rise against the normal limit while the level in the second compartment will remain normal.

Clog in Incoming and Outgoing Line

Clogs in the incoming line result in backups from the lowest plumbing fixture of a commercial kitchen. The main grease trap problem associated with this can be seen in the channels (the ones that divert everything towards the trap) which are blocked due to the excessive build-up of FOG and debris. This type of blockage is known to stop the entire grease trap unit from working.

Clogs in the outgoing line are comparatively easy to spot as that leads to overflows in both the compartments. However, this type of blockage can either be in the outgoing line or the city main. This type of grease trap problem can be evaded only by having your grease removal unit cleaned and pumped regularly by a grease trap service expert.

Overflowing Grease Trap

An overflowing grease trap is a result of not pumping out the grease from the first compartment in a timely manner. In this particular problem, you will see that the waste from the first compartment is spilling over the second one. The worse part, it will clog the crossover, outgoing as well as incoming lines. To verify the problem, simply dip a pole in the compartment to evaluate the depth of the grease trap. If it reaches the bottom, you should know that grease trap pumping is immediately required.

Rotten Smell

Rotten smell is another very common grease trap problem. While there are a number of issues that lead to a stinking grease trap, but the most common ones are:

  • If the opening of the grease trap gets degenerated, it will allow the gases from the grease trap to diffuse into your food establishment from outdoors. This type of problem can be resolved through simple gasket repair.
  • Over time, the plumbing in your kitchen might get occupied by heavy sludge which has to be removed by using a hydro-jetting machine.
  • Last but essentially not the least, if you do not clean and pump out the grease trap at regular intervals, it may lead to diffusion of rotten smell in the kitchen.

An ounce of prevention is worth a pound of cure. That is what we can say in case of the grease trap problems. Because they are as nasty on your pocket as they seem. Hence, to evade all these problems it is best to book a regular service of your grease trap rather than spending more on getting things repaired.
