Common Plumbing Issues in Restaurants and How to Prevent Them

Common Plumbing Issues in Restaurants

Plumbing issues can be a huge disaster in a restaurant business. Depending on how bad the problems are, they can put your toilets out of commission, let bad odors into the restaurant, interfere with your kitchen’s operation or even force the local authorities to shut down your business.

Because of the number of plumbing equipment and the amount of water they use, restaurants are highly-prone to plumbing issues. Managing the plumbing to detect and avert problems should be a major focus of your day-to-day programs to keep your restaurant operating smoothly and profitably.

Unless the issues with the restaurant’s plumbing system are kept to a minimum, they can become a huge drain on your business’ resources. You and your staff will find yourself spending inordinate amounts of time wrestling with avoidable issues that contribute nothing to improving the bottom line.

To manage a restaurant’s plumbing in a way that helps you avoid problems, you need three things:

  • You should know the common plumbing issues that are likely to happen in the restaurant
  • You should understand the cause of those problems and how to detect them early
  • You should have a licensed and experienced restaurant plumber who can solve problems quickly

In this post, we will talk about the common plumbing issues in restaurants and what you can do to prevent them.

Six common plumbing problems in restaurants and how to prevent them

Drain clogs caused by debris from the dishwasher are the number one plumbing problem in restaurants.

Clogged drains caused by mismanaging the dishwasher station

Drain clogs caused by debris from the dishwasher are the number one plumbing problem in restaurants. This problem results from servers not fully disposing of leftover food and other residue before dumping dishes in the dishwasher. The dishwasher washes this debris into the drain, eventually clogging it. Fixing this problem is simple; installing a wire mesh over the drain will prevent large debris from entering the drains. Training your servers to wipe dishes clean before putting them in the dishwasher also helps.

Clogged grease lines

Restaurants use a lot of grease and need a way to dispose of used-up grease. Sometimes, that used-up grease finds its way into the drainpipes instead of being disposed of in the trash bin. Once inside the pipes, that grease will harden, cling to the surface of the pipes and gradually block them. Issues with grease also happen with the grease trap. Although it is the designated grease-disposal system, if grease traps are not cleaned regularly, they can cause problems in the restaurant. You will want to hire a professional grease trap cleaning service to perform maintenance and cleanings on the regular.

Fryers and gas line issues

Clean your fryers every day. That usually means pulling them out to drain them. In this process, the gas line attached to the fryer may become loose. That can result in gas leaks and risks of fires in the kitchen. Gas lines, apart from issues with the fryer, can also have their problems. These are often due to defective gas lines, either from poor installation or improper maintenance. You can prevent this problem if you inspect the gas line regularly and your staff are more careful when handling the fryer.

Clogged floor drains

A clean floor is one of the things that make a restaurant attractive. Clean floors will make work easier and the restaurant environment safer for your staff. But restaurant workers often clean the floor simply by spraying it down and squeegee-ing all the water into the drain, along with any debris on the floor. The result is a constant problem with blocked floor drains. To prevent this problem, install a mesh strainer or drain lock on the floor drain to keep debris out of it.

Clogged bar drains

Like most of the issues discussed above, this problem is also caused by restaurant workers. Instead of throwing leftovers like cocktail-making components, lime wedges, orange peels and other items into the trash, bartenders simply flush them down the sink. These materials lodge inside the pipes and block them. Training bartenders and other staff who work at the bar on proper waste disposal will prevent this issue. You can also install wire mesh on the drain opening.

Maintain your restrooms

When a restaurant’s toilets overflow, it is often because paper towels and feminine hygiene products have been flushed down the toilet. To reduce the risk of visitors using the restaurant’s toilet as waste disposal, install hand dryers to make the use of paper towels unnecessary. Also, provide sanitary disposal containers for easy disposal of female hygiene items. You also want to ensure your restrooms are inspected and cleaned every hour.

Finally, you need the services of a commercial plumber to keep your restaurant’s plumbing systems functioning properly. But finding a good plumber is not enough; the kind of relationship you have with the plumber also matters.

Instead of contacting the plumber only when you have issues with your plumbing, it is better to have a service agreement with the plumber. The plumber can inspect your restaurant’s plumbing according to a schedule to find and fix problems before they worsen.

This method of maintaining your restaurant’s plumbing is the best way to avoid plumbing issues.

5 Important Plumbing Services for Restaurants

Important Plumbing Services for Restaurants

Modern restaurants use massive amounts of water in their day-to-day operations. Water is essential for food preparation and sanitation. Restaurant plumbing systems should be robust to handle the high volume of freshwater entering the facility and the high amounts of wastewater flowing into the drains.

Not only must the plumbing be perfectly designed for the type of restaurant, but it should also be the right match for the particular stage of the business, says Alliance Management Company. A common mistake new restaurant owners make is to treat their plumbing as secondary to other aspects of the business, such as the menu, efficiency of appliances and ambience of the restaurant floor.

But like these other factors, the design of a restaurant’s plumbing system can help or hurt the business. Restaurants need drainage, water and gas supply systems that are purpose-built so the facility can operate at its optimum. At the most basic level, a restaurant’s plumbing should have the following services;

New installations  

Restaurants often expand to accommodate their expanding customer base and enhance existing services. They do this by increasing the seating area capacity and adding new equipment to the kitchen. But to take full advantage of growth opportunities and avoid legal issues (that may result from violating city guidelines), they need to expand the systems that support these two areas. Add heaters, water supplies and grease trap installations to cater to the growing demand. Ensure that you install these new features in a way that creates a seamless flow between the functions of the kitchen, the interior of the restaurant, its restrooms and the supporting plumbing systems. Safety, attractiveness, durability and flexibility (to accommodate further expansions) are factors to consider when doing these new installations.

Installing sewers and drains

Huge amounts of waste are generated by restaurants, particularly during the food preparation process. This waste is created hourly and must be constantly evacuated to keep the kitchen sanitary and safe. Invariably, some of that waste finds its way into the drainage system, where it can cause blockages. This hourly assault on a restaurant’s drain and sewer lines is why the system must be planned properly. Compliant drainage systems with proper ventilation that prevent backflow from trapped air and drains that permit wastewater removal without reductions in pressure are essential features of restaurant sewer systems. That should be in addition to weekly plumbing maintenance to install new parts to prevent potential blockages and ensure the system’s smooth operation.

Gas lines for the kitchen

Restaurants should be able to constantly expand their capacity to offer good food to customers. To do this, they should be able to build on their existing infrastructure easily and at the lowest cost. Given that food is the main product of a restaurant, the business must have a premium gas line system that serves its present needs but also includes capabilities for future expansions. From inception, its gas line design should make room for possible future gas line extensions to serve a new or expanded kitchen. If this is not done, the cost of correcting that error may be too much for the business, forcing it to operate at a smaller scale than its capacity.

Grease traps   

Grease trap services are a vital service for restaurants. Restaurants use an enormous amount of cooking oils, fats and grease in different stages of food preparation. By day’s end, huge amounts of that grease will find its way into the restaurant’s wastewater. If allowed to flow into the city sewers and waste treatment facilities, that grease can cause expensive damage. Grease traps keep the fats, oils and grease in restaurant wastewater from entering the sewers and becoming a problem to nature and the city. They help keep the business’ operating costs low by preventing problems that would have happened if a grease trap was missing from the restaurant’s plumbing setup. By catching grease from wastewater and storing it until it can be removed, grease traps help the restaurant’s drain systems operate more efficiently. A grease trap needs to be cleaned out on the regular and well maintained at all times.

Plumbing repairs

Breakdowns and malfunctions in a restaurant’s plumbing systems can result in expensive downtimes. Waiting until problems happen before making an effort to fix them is not a viable plumbing maintenance strategy for restaurants. In order to avoid disruptions in the restaurant’s operations, plumbing issues must be detected before they result in delays. That means creating a watertight plumbing maintenance program overseen by a licensed professional who understands the higher working standards required in commercial plumbing and the very narrow margins for error.

To conclude, the foundation for building restaurant plumbing systems that can meet the present and future needs of the business is good design. Hiring a regular plumber instead of a commercial plumber for restaurants, when designing and installing the plumbing, is the main reason restaurant plumbing systems often fail to meet the necessary standards.
