Restaurants and commercial kitchens produce a lot of grease during food preparation. As it cools and congeals, this grease buildup will clog drain lines and potentially cause blockages and backups. Grease traps are plumbing devices designed to keep fats, oils, and grease (FOG) from contaminating wastewater before it enters the sewer system. Some are small enough to be installed under a commercial sink, while others require in-ground housing. Grease-trap sizing is determined by the amount of wastewater that is disposed of and is specific to each kitchen.

Grease traps are comparable to Inflammable waste traps in size and function. We hold FOG materials in a large steel basin, which allows sediment to settle and the FOG to form an oily layer at the top. Just as with inflammable waste traps, grease traps must be pumped regularly to remove the buildup of waste products. Grease traps must adhere to the 25 Percent Rule, which states that if the combined accumulation of floating grease or settled solids exceeds 25 percent of the trap’s capacity, a professional waste hauler must pump it. Some restaurants produce enough grease to be pumped on a weekly basis, while others can go two or three months between cleanings. No matter the frequency, it is important to keep close tabs on your grease trap. Approximately 50 percent of all sewer overflows are caused by grease blockages.

There are two types of grease that need to be removed from restaurants and commercial kitchens—yellow grease and brown grease. Yellow grease is used cooking oil, typically collected from deep-fat fryers. Yellow grease can be recycled and used to feed livestock or to make soap, makeup, clothes, rubber, detergents, and biodiesel fuel. Brown grease refers to all other FOG waste that has been captured by a grease trap. Because it has come in contact with rotting foods in the grease-trap receptacle, brown grease is unfit to recycle and must be disposed of in a landfill.

The best way to effectively control grease is to keep as much as out of the plumbing system. Scraping plates into the garbage before washing them, using drain screens on kitchen sinks, and wiping up spills with absorbent materials instead of spraying them with water are three easy ways to manage FOG discharge. This is as beneficial to your bank account as it is to the environment.

Water Jetting (1″-36″ line)

Drain King Inc Water Jetting TruckWater jetting—also known as hydro jetting—is an easy, efficient, and economical way to clear water and sewer lines of foreign objects that obstruct or impede the pipes. A special high-powered nozzle is attached to a flexible hose and fed into the sewer system. The nozzle blasts a concentrated stream of water through whatever is clogging the line. If you can envision the force and volume emitted by a fire hose, you have an idea of how effective water jetting can be.

Over time, sewer lines become contaminated with particles that stick to the edge of the pipe and impede water flow. Some of the most common culprits are FOG (fat, oil, and grease); ice, mud or sand; tree roots; mineral deposits; and items improperly disposed of in the toilet. Sometimes these deposits congest the pipes so badly, the wastewater has nowhere to flow but back from whence it came, so it is necessary to clean the pipes. This can be done with a cable machine, which can bore a hole through hair, sludge and tree roots, but is less effective at clearing debris than high-pressure water jetting. For this reason, water jetting has become Drain King’s and its clients’ preferred method of sewer-line cleaning.

The technique is simple:  We bring our pressure unit to your site, attach the appropriate water nozzle to our hose, send it through the drain or sewer line, and blast those clogs into oblivion at a rate of 4000 psi (pounds per square inch). We can hydro-jet any pipe from 1 inch to 36 inches in diameter, clearing hundreds of feet of clogged pipe with one treatment. The force of the water is strong enough to pulverize tree roots. This type of cleaning is so thorough, the full diameter of the pipe is cleared of deposits, producing a “like new” condition in the sewer lines. Even the toughest buildup can’t withstand the water-jetting process. And because regular water is used, the procedure is safe for the environment.

Restaurants, hotels, and other commercial businesses who have to fight FOG and soap-scum accumulation will find our water-jetting services especially helpful. Let Drain King flush away your most stubborn residue buildup and say goodbye to clogged drains.

Sand Trap

Sand Trap

Flammable waste tank
Sand Trap

Sand traps are typically found in parking garages, auto repair shops and large commercial spaces with floor drains. What most people don’t know is sand trap’s should be serviced (pumped) on an annual basis to prolong the life of the tank and protect the city sanitary sewer from harmful chemicals and oils.

What is a sand trap?

A sand trap is a tank that separates waste water collected from area floor drains. When liquid enters the tank, heavy debris falls to the bottom. Since oil is lighter than water it floats to the top. The remaining liquid flows through the tank and relatively clean water enters the city’s sanitary sewer system.

Servicing your trap on an annual basis is important to prolong the life of the tank. Over time, sediment will build up on the bottom of the tank. this can lead to major blockages and flooding throughout the garage. It is important to remove sand deposits before this occurs. Pumping the tank also prevents large amounts of oils and chemicals from overwhelming the system and distributing it into the sanitary sewer system.

Ice dams in Minnesota

Ice Dams

Ice Dam Removal

Ice dams are typically found on pitched roofs where heat from the building causes snow to melt and refreeze. They can also occur on flat roof buildings where roof overflow drains discharge water off the side of the building. Once ice dams form, water pools behind the dam. The pooled water may leak into the roof. This leakage can potentially cause damage to anything within the building.

Removing ice dams can be a delicate process. it’s not as easy as just chipping the ice away from the roof or wall as damage to the roof can occur. Drain King’s method for removing dams is utilizing hot water at low pressure. This method melts the ice away preventing any damage the roof.

Utilizing heat tape on the lower sections of roof or overflow drains is a great way to prevent dams from forming. This heat tape operates at low temperatures and prevents snow accumulation from building up on the lower section of roof or overflow drains.

Contact Drain King about ice dam removal, we service the following metro areas and more:
Minneapolis, St. Paul, Fridley, Columbia Heights, Bloomington, Blaine, Brooklyn Park, Brooklyn Center, Maple Grove, Maplewood, Eagan, Eden Prairie, Edina, Woodbury, White Bear lake, Golden Valley, Etc.

Plugged Storm Drain

Plugged Storm Drain


            A plugged storm drain can cause major issues for businesses, residential and industrial areas. Most plugged storm drains aren’t noticed until your building is flooding and its too late. preventing a plugged storm drain is easy. Remove built up debris before a plugged storm drain occurs!

Plugged storm drain

What Are Storm Drains?

A storm drain is a drain designed to carry rainwater that is gathered over an area water cannot penetrate. Rainwater is diverted to a catch basin or a curb and gutter system. Once in the catch basin the storm water will follow piping to different types watersheds (rivers, lakes and ponds).

What causes plugged storm drains?

Storm drains gather water from a large areas such as parking lots, streets or paved lots. While most of these areas are paved and cleaned periodically, they still collect debris. Debris can be anything from sand, leaves, trash etc. Parking lots and roadways are the largest contributors to plugged storm drains .  Although these areas are cleaned periodically, they still gather debris. Overtime this debris is slowly washed into the storm sewer and begins to build up slowly reducing the overall volume in which the storm sewer can handle. Once enough build up has accumulated the storm sewer may become overwhelmed during a rainfall event thus causing a back up to occur.

When should I clean my plugged storm drain?

Visually inspect your storm sewer catch basins twice per year for any signs of accumulated sediment or debris (Spring and Fall). While you may not be able to see inside the sewer line itself, noticing trash or leaves in the catch basin may indicate that you are about to have a plugged storm drain. If you notice standing water in your parking lot during a rainfall event it may indicate a plugged storm drain. If you notice any of these things immediately call a professional and have your storm sewer inspected.


Grease Trap Cleaning

Grease Trap Cleaning

A grease trap (also known as a grease interceptor or grease recovery device) is a tank designed to separate FOG (Fats, Oils and Grease). Fats, oils and grease originate from kitchen sinks and floor drains that are connected on the grease line. Dish washing, hood cleaning and floor scrubbing are all avenues for grease to enter the sewer line. While it may go unnoticed to most, grease trap cleaning is crucial to ensure sewer lines flow properly.

Locate Your Grease Trap

It is important to know where your grease trap is so you can manage it properly. The location of the grease trap is dependent on size and available space. Most internal grease traps are 50 gallons or less. Some traps are large external tanks that can hold up to 2000 gallons of liquid.


Cities Require Grease Trap Cleaning

Most cities require commercial kitchens to install grease traps to prohibit large amounts of grease from entering the sanitary sewer system. In some cases, restaurant’s without grease traps have caused major blockages in the city sanitary sewer. The backups can lead to large fines and clean up cost to the owners. Grease trap cleaning contracts are now required by some cities before plumbing inspection are completed. Grease haulers take the unwanted brown grease and dispose of it at proper liquid waste disposal facilities.

Traps can overflow and shut your restaurant down causing lost revenue and expensive clean-up costs. The cost of grease trap cleaning pales in comparison to the cost of these expensive clean-ups. Grease trap cleaning, on a preventative basis will prolong the life of your grease trap and keep it functioning properly. Overall, The cost of grease trap cleaning, in the long term, will save you thousands of dollars.

Parking Ramp Drain Cleaning Drain Cleaning For Your Ramp

Parking Ramp Drain Cleaning

Winters in Minnesota can be downright brutal. Cold temps and heavy snowfall lead to slippery roads and treacherous driving conditions. To combat these conditions the Department of Transportation and other municipalities spread large amounts of salt and sand on Minnesota roadways. When driving in such conditions, vehicles accumulate large amounts of wet snow around wheel wells and tire rims. the snow contains large amounts of sand and salt.  Where does all this sand and salt end up? In your parking lot drains and sand traps.

Parking ramp drain cleaning on annual basis, is crucial to the life of your parking lot drains and sand traps. If neglected, the salt can break down cast iron pipes causing the pipe to rot from within. Rotten pipes can lead to costly floods or repairs to vehicles within the ramp. The Sand trap can also deteriorate from salt deposits. Sand traps will start leaking if not pumped frequently enough. Not only will you need to replace the tank, you will be stuck with expensive clean-up costs.  Pumping your sand trap at a minimum of once per year will prolong the life of the tank and prevent costly Hazmat clean ups.

high pressure water jetting

Drain King uses high pressure water jetting to remove sand and salt deposits from the parking ramp drains. All left over waste is pushed from the top of the ramp to the bottom. after jetting, all waste is pumped out of the tank. All liquid waste is disposed of at Met Council. The sand is disposed of at a local landfill. Low clearance ramps are no problem for Drain King Inc. Vac trailer. This trailer can access sand traps in almost every “low clearance ramp”. Parking Ramp Drain Cleaning keeps your pipes healthy for the long term.

Purchase home main sewer line televising.   You are probably getting a home inspection.  The inspector looks at many things then gives you a report on his/her opinion of the health of your perspective home.  Some home inspectors offer an add-on service of main sewer line inspection.  The customer can also contract this service directly.  Drain King, Inc.  https://drainkinginc.com/  provides this service and many others.  Your sewer line can be a source of massive problems and can be a reason inscrutable home owners sell a home.  Someone else has to pay for the problem.  I’ve seen it happen.  Sewer line repairs are at least $5,000 and can exceed $30,000.  There is no reason to be victimized.  In some situations nobody knows there is a problem.

An Example of a failure;

In one case a business purchased a multi-million dollar building and 2 years later paid $15,000 to figure out where their sewer line went and have structures installed so it could be cleaned on a regular basis.  I was part of a telephone negotiation between several parties deciding who was at fault.  My response to the building owner was; “people buy a $200,000 home and pay $200 to have their sewer line inspected.  You bought a 7 million dollar building and didn’t even consider having the sewer line located and inspected”.  That sewer line was over 700 feet long.

The sewer line in your perspective home is probably less than 100 feet.  If your home is further than 50 feet from the city street it is extremely important to know where the sewer line is going.  You need to know it’s condition and where additional clean outs are located in case there is a problem.  You should also mark outside clean outs since you may have to find them under 2 feet of snow.

Restaurant Grease Do’s and Don’ts.

Restaurant Grease Truck – Pumped Grease

“Insanity is repeating the same thing over and over and expecting the results to be different.”, is a quote often attributed to Albert Einstein.  I recently had a restaurant owner angry with me at the cost of clearing his main line of restaurant grease.  The process took 4 hours and required a 4,000psi jetter at 18 gallons per minute, and a vacuum truck so the store would not flood while we were working.  He told me he had been the manager of restaurants for 20 years and never paid this much to have grease cleaned from the lines.

I explained to him he paid about the cost of 1 year’s maintenance to keep restaurant grease from plugging the drains in their building.  Routine maintenance for a restaurant with grease issues is 2 to 4 times a year.  Some restaurants need to be done monthly.  Some restaurant owners and managers believe a grease trap in the store means all grease will be stopped from entering the building sanitary sewer.  This is not true.  Restaurant Grease traps are not meant to stop 100% of the grease from entering the  sanitary sewer.  When functioning properly Restaurant grease traps stop approximately 85% of the grease leaving 15% to flow into the restaurant’s sanitary sewer eventually plugging those drain lines.

Loss of Revenue and loss of customers because they are angry that your restaurant is not open is not good for business.  Even worse is customers that will never return because they are disgusted by the smell caused by backed up grease drain lines.  Do’s and Don’ts?  Do contact us now drainkinginc.com  for a free appraisal and/or estimate.  Do recycle cooking oils.  Do empty your grease trap at least quarterly.  Don’t repeat the same mistakes.  Don’t think everything is fine because there is nothing backing up on your floor or in the customer’s restrooms.
