However, it is vital that they are kept in the same great condition as your internal drains. Here are our top tips on how to unblock an outside drain.

Finding The Source of a Problem – Why is my drain blocked?

You might find that your drainage is slowing, there is an unpleasant smell, or you have spotted other signs your drains may be blocked. These are all caused by blockages to your outside drains. The first thing you should do when you find your outside drains blocked is to assess the problem and see what is causing it. You should lift the drain cover to give you the best idea of what the problem is. You might find that you need a screwdriver to do this. There will be a few of these covers around your home where the blockages could be.

When looking in the drain, there should be flowing water and no visible signs of blockage. A blockage can be identified if the water in the drain is blocked and not flowing. Outside drains are often blocked up with leaves and other types of debris and dirt.

How To Unblock An Outside Drain Yourself

There are a couple of methods you can use to unblock outside drains yourself. Here are our suggestions:

Drain Rodding

Drain Rods are used by many plumbing professionals to unblock drains. You can buy drain rods online or in any good hardware shop. Here is a cheap set of drain rods. They are used to disrupt and dislodge debris that is causing the blockage. Twist the drain rods around in a clockwise motion to break up the blockage. It may be a particular bad blockage so persevere and your drain should be back to normal. It’s not a glamorous job, but someone has to do it. Safety is the primary concern here, so make sure you are wearing protective clothing. This method should disrupt the blockage. If not, Maintain Drains offer an expert drain rodding service.

Caustic Soda

Another method you can use to unblock an outside drain is using sodium hydroxide (caustic soda). Drop some of it in your drain along with some water. This will cause the debris causing the blockage to rise to the surface where you can fish it out. Note that there can be dangers when using chemical drain cleaners. Have a look at our blog here.

How To Prevent Blockages To Your Outside Drains

Maintaining your outside drains is an important process to ensure that your whole drainage system is working properly. Firstly, do not throw grease down your drains as this causes blockages and fatbergs. You can cover the opening of your drain with a screen to make sure debris does not enter the drains. Cleaning your drains regularly with bleach will help your drains continuously run smoothly.
