Grease Trap Pump Pit Repair and Replacement

Grease Trap Pit Collapse

This job is a stinky one. The room is small and the grease trap pump pit has got a collapsed wall and the grease water is flowing through the soil and sand and making its way to the stormwater and this is causing an excessive smell in the basement carpark.

Our job is to dig out the old grease trap pit which is fibrecrete which is concrete mixed with fibreglass. Over time these tanks whether a larger grease trap or a pit will breakdown and collapse. Plastic replacements are definitely the best solution or if this is not possible due to costs you may need to form up a new pit and waterproof the tank.

We prefer the plastic tanks by far from companies like Viking Plastics, CV Plastics and Halgan. They all make excellent products. The  reason we use different companies is that not all jobs are the same and these companies all have different tank options and sizes that may be best sorted for a particular installation.

Grease Trap Plumber Inner West Sydney

Grease Trap Installation in Newtown, Sydney

The shop is a long and thin shop on King Street, Newtown. Due to the amount concrete footings or foundations we needed to change our original plan of having the grease trap installed outside to moving it to the inside of the shop.

We installed the grease at the rear of the shop and needed to alter the plans or drawings to call that section a bin room. The room need to be vented to outside, which we achieved by cutting a square in the back door and installing a air grill. If we could get access to outside for ventilation then we would need to install mechanical vent skills or exhaust fans.

This property also had a grouped sewage system so the main sewer connection was in the neighbours shop and this meant we needed to cut open in their courtyard a smallish section of concrete so we could make our grease trap pipe connection at a lower point so as to have gravity fall from the grease trap outlet.

The job was all successful despite the issues associated with the excessive amount of concrete. Both Sydney Water and The Department of Fair Trading gave us approval on the completed job.

Repairing A Cracked Or Damaged Grease Trap

Is Repairing A Cracked Or Damaged Grease Trap Possible?

Short Answer: No

Long Answer: Yes

Some grease traps can be and other grease traps can not.

Also depends on accessibility. Some commercial kitchens and restaurants have concrete, plastic or fibreglass grease traps in the most inaccessible place known to man. Having said that though, sometimes the only solution in this scenario is to repair. Please read and see if your system is repairable.

Concrete Grease Traps

Concrete Grease Traps are possible to repair.  It takes great effort and expense to do so though.  The cracked area needs to be cut away and patched up according the the best practices to bond concrete.  The whole concrete grease trap needs to be ground back to a rough surface and a very high quality resin needs to be used to bond to the concrete grease trap walls and base and to make a completely water tight seal.  Off course this procedure is more involved then what we have just mentioned but you may get the idea that this can be done but will be costly.  In some cases this is your only option and replacing the concrete grease trap system will not be possible.

Plastic Grease Traps

Plastic Grease Traps are less likely to need repairing as they are long lasting and durable.  But for this example lets look at how they can be repaired.  If there has been a break or crack in the plastic grease trap it needs to cleaned out thoroughly and sanded back to a raw plastic surface with no contaminates around the damaged area.  A large piece of plastic provided to you by the grease trap manufacturer can be plastic welded over the damaged area on the plastic grease trap.  If this is done correctly it will be a permanent repair.  This makes plastic grease traps long term friendly.

Fibre Glass Grease Traps

Like Plastic Grease Traps, Fibre Glass Grease Traps can be repaired.  In much of a similar way also.  The break or crack area needs to be thoroughly cleaned and sanded back to a raw fibre glass surface with no contaminates.  A large piece of fibre glass needs to be applied over the damaged area on the fibre glass grease trap.  If this is done correctly it can be a long lasting repair.  This would be a good opportunity to re glass the whole grease trap tank as they age and the fibres start to pull away from the walls.  But to answer the initial question, fibre glass tanks can be repair successfully.

How To Choose A Grease Trap Plumber

How To Choose A Grease Trap Plumber

Whether you choose to use Scooper Plumbing or not, please make sure that you choose a plumber that has lots of experience installing Grease Traps. Here are some good sound reasons for this.

1:  If the plumber is not familiar with the extensive amount of regulations surrounding any grease trap installations, then in most cases the grease trap may be installed incorrectly.  If this is the case, your business will be unable to be opened until the Water Authority has given it’s approval.  In some cases you may be forced to have the non compliant grease trap installation rectified before they will issue you a final approval.  This may cost you thousands in lost revenue, plus a large extras bill for work that was not allowed for in the initial quote.

2: The plumber who is not so experienced may promote a system that is technically ok, but not the best or cheapest option for your business.  Sometimes a long term view and a minor change at the construction stage may save thousands over the next 5 year period as well as long into the future.

3:  The wrong choice of grease trap and the wrong sizing can be a thorn in the flesh.  Pump systems are great and in some cases they are the only possible option. But they come with a bitter twist as they fail when you are at your busiest period in the week.  We always seem to have to attend to grease trap pump failures at 9PM on a Friday or Saturday night to attempt to repair a blocked or burnt out grease trap pump system.  Try to visualise the kitchen floor with all your staff working with a few inches of drain water around their feet and everything now up off the floor and on the benches and you this are trying to serve customers ad not them know anything has gone wrong or the food is not contaminated in anyway.

Grease Trap Installation

Grease Trap Repairs and Replacements

Grease Trap Repairs and Replacements are very common as most of the Grease Traps installed are made from fibre glass or concrete.  These Grease traps are very good but they do have a shelf life due to the nature of the material and the corrosive element of the grease trap contents.  The companies that make the concrete and fibreglass grease traps are solid and reliable and do a great job but the concrete and fibreglass ones just don’t last as long as the poly systems.  Having said that, there are many instances that can only be fulfilled by a non poly system.

Poly Systems are very durable and long lasting and perfect for grease trap repairs/ replacement options.  Once again the company that makes these plastic grease traps are a very good and trustworthy business as well.  Plastic grease traps are a little easy to install as they weigh less then the other grease traps and do not always require a crane to lower them in to position.

Poly or Plastic grease traps are called Modular Grease Traps.  What does this mean?

The plastic Grease Traps come in 500, 600,1000, 1100, 1500, 2000, 3000 ,l4000 and 5000 litre tanks.  Lets say you have a large restaurant or its for a food court and you require a minimum of a 5000 litre grease trap. If you wanted a plastic modular grease trap you would have to join say a 3000 and a 2000 litre grease trap together via a drainage connection pipe and this would now be a 5000 litre grease trap.

Why would I do this?

If your old system has collapsed and there is know way of getting a large concrete or fibreglass system into this same location as the building has been built around or over the grease trap then the modular grease trap system is ideal.  You are able to take in smaller tanks through the building and still meet the litre requirement.  This is just a basic look at your options. Off course not all situations allow for either system to be installed.  There is generally always a way.

Key Points:

Poly Grease Traps may Last Longer and ideal for grease trap repairs and replacements.  Easier to move in to position.

Concrete and Fibreglass GT’s may be the best and only option for Large systems

What Businesses require a Grease Trap?

Q: What Businesses require a Grease Trap?

A: Mainly Cafe’s, Restaurants, Bakeries, Takeaways, Butcher’s shops and various other food preparation businesses. The purpose of a Grease Arrestor/Trap is to keep the fats and oils out of the Authorities sewer lines and they also serve as a means of preventing blocked drains on your property. The main reason for complying with the Regulations is that your business will not be able to open unless the list of requirements regarding Grease Trap installations are met. Most Council Authorities and the Health Department regulate that they are installed and inspected to meet their conditions.

What type of Grease Trap Tank or System should I get?

Q: What type of System should I get?

A: It will depend on the position the Grease Trap is to be installed. We alternate between three Companies solely based on the actual ability to fit it through door ways, take them up or down stairs or fit them in that room. Each choice is site specific. Both Companies make great products.

The two types of systems that we personally recommend are the Fibre Glass grease traps and the Poly/Plastic grease trap tanks. Both are made to meet all of your Local Authority Standards and are long lasting.

Concrete tanks need to have an Epoxy lining applied each year which no body does and for this reason they break down rapidly due to the cement being porous. This can be very costly.

One company makes the High Quality Fibre Glass Grease Traps and other Tanks and the other 2 Company makes High Quality Poly/Plastic Grease Traps and other Tanks. Both systems come with industry standard 7 year warranties.

Can I have an Above Ground Grease Trap Instead of an in-ground GT

Q: Can I have an Above Ground Grease Trap Instead of an in-ground GT

A: You can, but if the kitchen floor is lower then the top of the Grease Trap then in this case you will need a pump to push the water into the grease trap. The pumps are costly and sometimes the installation costs are very similar between an above ground and in-ground system. Not all states allow the use of grease trap pump stations.

If gravity fall is not obtainable on a below ground system then Risers are available in various sizes. Once again not all States allow the use of risers.

How often do I need to have the Grease Trap Cleaned out?

Q: How often do I need to have the Grease Trap Cleaned out?

A: Many local Authorities require that the system be cleaned out every 13 weeks or 3 months to start with. A Trade Waste Inspector will visit your premises from time to time to inspected the “Fatty Crust” or grease build up. He will then decide that your system needs to be cleaned out more or less often. It is not base on an opinion but on the measurements the Inspector records. Bigger systems always cost less in the long run, because your on going costs are less.

A point of caution is that if you have a small Grease Trapand a large water usage then you may find that you have to have your Grease Trappumped out regularly. As pump outs are over $200.00 each time, the cost of installing a larger system may be the most cost effective option. Deciding to install a Grease Trapat your business is not for those interested in being involved in this business for only a few years, but rather you are expecting be in this business for the long term. With this in mind, a bigger Grease Trapcan be Cheaper. Something to ponder over.
