6  DIY common oversights: underground drainage pipe installation

A proper drainage system is a must in every property. However, the installation of a drainage pipe network is not always easy. The mistakes during installation cause complications further down the line.

Preparation is key

To install the drainage pipe right, you have to know all the details. In most DIY pipe installation processes, the homeowners overlook the importance of choosing the location for collection point – i.e. a minimum 6 feet away from the foundation. If you are installing plastic pipe work in the winter months, take your time when cutting pipe as it will be more brittle because of the lower temperatures and therefore will be more prone to fracture or cracking.

Don’t overlook the utilities

You may have started digging the ground, however, it is essential to speak to your local council or Municipal authority. If you are installing new runs of underground drainage or you are converting or changing existing “runs”, you are legally required to inform the authorities. The professionals in this department will tell you whether there are cables, running underground. Hitting an underground cable can be costly and dangerous. Before you begin your drainage pipe project, do not forget to call ahead and get your utility lines marked. Like any project that requires digging, marking the utility lines will help avoid unnecessary damage to your property and fines.

Is the pipe level consistent?

In consistency in pipe level (once it’s laid) may cause issues.  The route of the drainage pipe should be as direct as possible. This will be easier if you are using it to deter water from a specific area. Do not forget to account for the necessary downward slope. You may also find water accumulation and leakage occurs. Sharp angles can also cause this issue.

The drainage pipe needs to be set in a trench. Dig the trench along the route you have already decided upon. The trench needs to be eight to 10 inches wide and about 18 inches deep. When you shovel the sod to start the trench, keep it and set it aside as you will need it to cover the finished job. It is important that the bottom of the trench be firm and always sloping down in the direction of where you want the water to end up.

Adjustable bends

Adjustable bends are essential to make connections into the present drainage. The newly added pipe must have a consistent alignment with the present setup. Find what you need in our large selection here.
