Silt traps exploit gravity: water slows in the chamber, sediment sinks into the sump, and cleaner water exits above. They protect soakwells, pump wells and long pipe runs from progressive silting.
Like any trap, they only work while there is room in the sump — a full silt trap passes everything straight through.
Stops sediment travelling into and clogging downstream drainage.
Upstream of soakwells, pump pits and in landscape drainage systems.
A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
A CCTV drain inspection shows exactly what's happening inside your pipes — no guesswork.
