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.
If you think the property you want to buy could have
pitch fibre pipework, please contact Dyno-Rod on FREEPHONE 0800 112 112 for further advice or to arrange a site
