How to Prevent Blocked drain from oil & fats

Drain Unblocking in Dublin 

We're all guilty of letting extra oil and fat go down the drain in the kitchen, but in this day and age of environmental consciousness and drain unblocking gets difficult, it's important to practice effective commercial kitchen waste management because FOGs can have some seriously negative effects in commercial kitchens.

Nothing like the miseries of a blocked drain can derail a hectic Saturday sales time, delaying that crucial service schedule and causing havoc in the kitchen.

A minor obstruction can quickly become a larger issue, leading to leaks, electrical damage, and overflows. All of these can be extremely expensive for a firm and perhaps result in business closure.

In order to determine just how much of an issue blocked drains can be, we questioned the experts—a number of engineers from Stillorgan Drain Cleaning—about their experiences. While 50% of the engineers we surveyed said they dealt with drain-related issues in restaurants on a daily basis, 78 per cent of them said they are called out at least once a month.

It is actually very easy to keep the drains in your commercial kitchen clear and unclogged. Here are our best recommendations for keeping them clear of oil.

Educate Your Staff

94 per cent of the engineers surveyed said they have been called out to unclog oil and fat-clogged drains. Despite being hot, oils can still clog drains. It's a common myth, but once the oil cools down, it hardens and won't move without professional assistance.

Our engineers' most frequently recommended method of preventing drain blockages was training personnel on how to dispose of FOGs properly. The largest problem, according to 70% of our engineers, is ignorance. Spending time teaching employees what can and cannot be flushed down the drain can ultimately save firms a lot of money. It all comes down to altering our behaviour.

Provide workers with alternatives to simply washing everything down the drain and emphasize the need for preparation. Tell them to scrape away any waste and put it in a trash can before wiping down the dish with a paper towel to remove any remaining oil.


Install A Grease Trap!

To ensure that your personnel can properly dispose of fats and oils, make sure the appropriate facilities are available. The lack of suitable facilities frequently results in significant drainage issues, as noted by 62% of the engineers, and several of them recommended adding grease traps to address the problem.

Before FOGs can settle in drains, grease traps stop them, separating the water from everything you don't want to flush down the drain. You should periodically check on them to make sure they're functioning properly; you'd be surprised at how much oil, fat, and grease they accumulate.

Don’t Let Coconut & Rapeseed Oils Fool You

One of the engineers observed that although "fashionable" oils like coconut oil are exactly as dangerous as conventional cooking oils, many consumers tend to ignore this. When disposing of "fashionable" oils, it's crucial to use the same caution, therefore owners could find it helpful to post signs around the kitchen to remind personnel of this.

Remember that other substances besides oils, fats, and grease can also clog drains. To avoid undesired food from clogging the drain, ensure every sink has a strainer. You should also never brush extra food down floor drains because it all ends up in the same spot.

So how should you dispose of oils & fats?

FOGs can be disposed of in a variety of methods. It is worthwhile to consider some possibilities, even in a household environment. One straightforward method is to properly allow all cooking fats to cool before disposing of them after they are solid. However, it is preferable to save the used oil and take it to your neighbourhood recycling facility when utilizing a deep-fat fryer or in a business setting. Simply inquire about the services available from your local council.

Unclogging a fat-clogged drain takes a lot of time and money, but it is something that may be easily avoided with some careful planning and adequate FOG disposal. Many of our customers would have preferred to avoid a large number of home and commercial fat blocked drains that we are called to each year.
