Do you need to gain access to a manhole cover? If so, ensure you are authorised before proceeding, i.e. have permission from your local water authority or utility company.
Bear in mind that you can only access a public manhole if you are professionally trained and are required to do so as part of your job, i.e. you’re an electrician, plumber, or drainage specialist.
Once you have the necessary permissions, you can remove the manhole cover. If you don’t have a manhole cover key, there are other tools you can use to gain access.
So, wondering how to open a manhole cover? Continue reading this blog to learn more about manhole covers and how to safely remove one when you don’t have a key.
What is a Manhole Cover?
Manhole covers are situated in various locations like roads, footpaths, car parks, and sometimes even on the grounds of a residential property, to name a few.
A manhole cover is a removable lid for a hole in the ground that enables access to public services like our sewer network, drains, electric, gas, and telecoms. Manhole covers keep the public safe since these services, such as sewers, can be dangerous for various reasons.
Why are Manholes Dangerous?
First, manhole depths vary. For example, some are shallow, and some are deep; either way, you wouldn’t want to fall down one.
Secondly, sewage contains harmful bacteria that can cause serious illness.
Of course, electricity and gas are dangerous if you don’t know what you’re doing or fail to use correct safety procedures.
So, if you need to access a manhole, wear protective clothing, such as gloves, safety glasses, and boots.
What are the Reasons to Access a Manhole?
You may need to access a manhole for one of the following reasons:
- Perform essential repairs
- Conduct cleaning tasks
- Make a routine inspection
As mentioned, you must obtain the necessary permission before removing a manhole cover.
However, if the manhole cover is in your garden and you’re the homeowner, it is your responsibility, so you shouldn’t need to gain permission elsewhere.
Manhole covers on your property are likely to enable access to your drains.
How Much Does a Manhole Cover Weigh?
Manhole covers tend to be heavy to prevent unauthorised entry and withstand high traffic. Their weight does depend on their application, but some can range up to 250 pounds, which is around 115 kilograms.
Lightweight ones tend to be found in gardens, driveways, and other pedestrian areas.
Heavy-duty applications require weightier manhole covers, such as those in docks and airports.
Some manhole covers are made of cast iron, while others are made of steel; however, steel is not as strong as cast iron, so they are classed differently.
Opening a Sealed Manhole Cover Without a Key
The recommended way to open a manhole cover is with a key; however, if you don’t have a manhole cover key, there are other ways to open it.
Remember to acquire the necessary permissions and apply safe working practices. Wear the appropriate protective gear, such as heavy-duty gloves, and proceed cautiously, clearing the area of any obstacles and debris beforehand.
Follow the below steps to remove a manhole cover:
1. Use a Screwdriver.
Run your screwdriver around the edge of the manhole cover’s rim. Use a flat-head screwdriver to enable you to apply sufficient force.
2. Soften the Soil.
If the manhole cover isn’t budging, pour water around its edges to soften and loosen the soil.
3. Use a Hammer.
Hammer the screwdriver carefully to force it under the lid and pry the manhole cover open.
4. Get a Firm Grip.
Locking pliers may help you to get a firm grip on the manhole cover. Our Bahco 250mm Locking Pliers have a narrow jaw to enable a tight grip.
5. Test the Weight.
Once the manhole cover is loose, test the weight of it with a tool, such as a spade.
6. Use a Crowbar for Leverage.
Ideally, do not lift the manhole cover with just your hands. Consider using a crowbar for leverage.
7. Check Your Stance.
Make sure you have a good lifting stance to prevent back injury. Also, ensure that your tools can effectively support it.
8. Ask for Assistance.
At this stage, you may be wondering how to lift the manhole cover.
Well, removing the manhole cover may be a two-person job, particularly if it is cast iron, so ask for assistance if it is required.
Change into Appropriate Protective Gear.
Once you can access the manhole, proceed cautiously, particularly if it’s a deep hole. Remember, ensure you’re wearing appropriate protective gear according to the task you’re undertaking.
Now you know how to remove a manhole cover without a key!
Whether you need to carry out repairs or a routine inspection, by following these steps, you should be able to effectively and safely access a manhole. But before you do, don’t forget to acquire the necessary permissions from your local water authority or other utility company.
