Sewer backup

What's more unpleasant than experiencing sewer backup?

The first action following a sewer backup is to unblock the drain if it is a drain blockage that caused the backup. After unblocking the drain, we need to know what the cause is in order to definitively resolve this problem and prevent it from occurring again.

Here are the main causes of sewer backup:

Root problem in building drain
Counter slope of building drain
Non-return valves missing or faulty
Drain Sagging
Offset from the drain
Dirt buildup in the drain
Using a camera, we are able to have a clear image of the situation, which allows us to correct the problem permanently.

Pressure cleaning your main drain is also a good way to prevent rather than cure.
