Have Your Drains Collapsed? Everything You Need to Know

Collapsed Drain Pipe

A collapsed drain is one of the most extreme drainage issues that we deal with, often caused by years of poor drain maintenance or damages and cracks in your pipes.

How do I know if my Drains Collapsed?

You may also notice a persistent blockage in your drainage system. The smell of sewage is also a common sign of a blocked drain so you might find it disappears after you have your drains unblocked. However, the unpleasant smell will return in due course if you are dealing with a collapsed drain.  Maintain Drains recommends that you consult a drain expert when you notice the smell of sewage or have a persistent blockage in your drainage system. A drainage expert can assess the drainage, often with a CCTV drain survey, to find out if you have any major issues with your drains. Even if your drainage problem is a minor blockage, you will have peace of mind.

Other Signs of Collapsed Drains

Persistent blockages or the smell of sewage are often the first signs of collapsed drains that you may notice, but you should also look out for the following:

1. Damp or Mould Around the House

Rising damp or mould is another one of the more common signs of a collapsed drain. This usually appears around the house in floors and walls and is caused by waste water failing to fully leave the property.

2. Damage to the Building

One of the more extreme signs of a major collapsed drain or a compromised drain that has gone unnoticed is damage to the building itself. As well as causing a growth in mould or dampness, waste water failing to drain properly can cause cracks to your foundation or walls in extreme cases.

3. Infestations

Rats thrive in drains and sewer systems, and so a crack in your drain pipe might attract rodents. Collapsed drains can also give rats access to your home.

4. Sinking Ground in the Garden

If you notice wet patches of grass or soil, contact a drain expert as soon as possible.  If you spot any of these signs, it’s important to contact a drainage specialist immediately to receive advice. Whether it’s a new smell of sewage or a sinking patch in the garden, inspection from an expert as soon as possible can help to resolve the problem before it can get worse, saving you both time and money.
