roots of a gunnera plant

Question

Are the roots of a gunnera plant known to become intertwined with the water system of a house?

Answer 1

I don't know whether this plant commonly has damaging roots, but it's certainly plausible since its root system is quite large. This is something to have an expert check on in case it is causing damage.
