Between the old cast iron on one side of town and hard water everywhere, Hanahan drains collect more than most — which is exactly what jetting is for.
Clearing and cleaning are different
A cable makes a hole through the blockage so water runs again, but everything coating the pipe stays where it is. That is why the problem returns sooner each time. Jetting washes the walls of the pipe back to the material underneath.
Two reasons it works well here
Older cast iron in the original streets has decades of buildup narrowing it. And across the whole of Hanahan, hard water leaves scale inside drain lines alongside grease and soap. Both are deposits a cable passes straight through without shifting.
Useful after roots have been cut
Once roots are removed from a line, jetting clears the fine material left behind that would otherwise catch the next thing to come down.
When we will say no
Old cast iron or clay that has already thinned may not stand the pressure, which is exactly why we look with a camera first. On a fragile line we will recommend lining instead of risking turning a blocked pipe into a broken one.
