Although considered suitable for foul drains and sewers, it was not considered suitable for drains running large amounts of hot water or for wastes containing pitch solvents such as fats, petrol, oil etc.

Dyno-Rod’s experience over the last 40 years has shown the following problems can occur with pitch fibre pipe used for foul drainage:

1. Over a period of time the pipework can deteriorate through being poorly laid, age, weakening weight stress and chemical erosion.

2. The pipework can become porous, allowing water to leak out. Subsoil is then washed away from around the pipe causing subsidence.

3. If the pipework leaks it may attract tree or shrub roots causing further damage.

4. Pitch fibre pipework is prone to deterioration from within by blistering, causing obstructions and eventually closing up the pipe.

5. The usual forms of pipe maintenance carried out on pitch fibre pipework may actually cause further damage due to its delicate nature.

By our high standards, pitch fibre is a very poor drainage material. It has a limited lifespan, but nobody knows how long as each run is different.
