Trees, gardens and what lies under the ground
Redland has leafy streets and many front and back gardens with mature planting. Trees look good, but roots seek out moisture, and old clay drains with loose joints are an easy target. Slow flushing, gurgling and a smell near a manhole are common first signs.
In autumn, leaves and silt also gather in gullies at the foot of downpipes. If water backs up outside after rain, a blocked gully is a cheaper cause to rule out before anyone suspects a collapsed drain. Cellars that stay damp are worth mentioning too, since they can hide a leaking supply pipe.
