Drain Descaling and Jetting in Coalville

A detached house in Coalville with a drain that had stopped running as it should. Not blocked outright — just slower than it ought to be, and getting slower.

The camera showed why. Scale had built up along the pipe wall — hardened deposits that narrow the bore a little more each year until there is not much pipe left to flow through.

That is worth understanding, because it is not the same as something going down the drain and getting stuck. A drain like this rarely blocks all at once. It slows, gets rodded, runs freely for a while, then slows again — because rods push a channel through the middle of the build-up and leave the rest sitting exactly where it was.

We cleared it with high-pressure jetting, which cuts the scale off the wall and flushes it out rather than boring through it, then put the camera back down to confirm the pipe was back to something close to its original bore.

A pipe running at full bore again rather than through a channel in the middle of its own build-up. An hour on site. The difference between this and rodding is not what the drain does today — it is whether it is still clear next winter.
