Drain Rat Blockers in Chesham

Chesham sits in a valley with housing running up both sides, and drainage on a slope behaves differently from drainage on the flat.

Steep runs scour rather than silt, which is mostly good. What they also do is move, and terraced housing on a hillside frequently shares a run down to the street.

Terraces on a slope

One Run, Several Houses

Where a terrace steps down a hill, the usual arrangement is a single run picking up each house in turn before it reaches the road. That has two consequences worth knowing.

First, it is a sewer rather than a drain, because it serves more than one property, which usually makes it the water company's. A defect in it is theirs to repair.

Second, a blocker cannot go in a shared pipe. It goes in your own branch, between the house and the point where you join, which closes the route into your property and leaves everyone else's arrangements alone.

On a slope there is a third consideration: fitting a valve into a steep run needs care, because you want it where flow is controlled rather than where it is fastest. That is a placement question and it is one of the reasons for looking before fitting.
