Inspect first
A blockage at the gutter outlet needs a different approach from one at the underground connection. We work out where it is before starting.
A blocked downpipe looks harmless from the ground, but the water it should carry away ends up over the gutter edge and against the house. Caboolture Plumbing and Hot Water clears downpipes from the gutter outlet through to the underground stormwater connection and confirms the water gets all the way to the outlet.



A blockage at the gutter outlet needs a different approach from one at the underground connection. We work out where it is before starting.
High-pressure water breaks up and flushes leaves, silt and nests without damaging the pipe. It works from the top or from the base.
For a downpipe that keeps blocking, or where roots or damage are suspected underground, the camera shows what is there before anyone digs.
We run water through and check it arrives at the stormwater outlet, not just past the point where it was blocked.
Leaves and seed pods wash off the roof and into the gutter until the downpipe opening seals over. Blocks with mature trees, and older streets with established gums and camphor laurels, see it most. Nesting birds and possums use an open downpipe too.
The other common site is the bottom of the pipe, where it joins the underground stormwater line. Silt and compacted leaves settle there for years, and tree roots find the joint. A downpipe blocked at the base looks fine from above and still backs up.
Older downpipes can crack or sag internally as well, which restricts flow with no visible blockage. The camera is the only way to see that.
A garden hose or a drain rod will often shift loose debris near the top of the pipe, and that is worth trying. Beyond that point the risks change: forcing rods into a downpipe can compact the blockage or crack an older pipe, and the underground connection needs a jetter.
If a flush from the hose does not clear it, stop there. The repair for a cracked pipe costs far more than the clear.
Downpipes rarely block on their own, so we check the gutter outlet and the underground line at the same time.
Tell us which drains are affected and whether water is coming up anywhere. That decides what goes on the van.
The plumber checks the fixtures, the overflow gully and the inspection openings, and runs the camera when the cause is not obvious.
You get the price for the clear before we start. Relining or replacement is quoted separately if the camera shows damage.
The line is cleared, checked with water running and, where damage was involved, inspected again with the camera. You are told what caused it.
The downpipe nearest that spot is blocked, or the gutter outlet feeding it is. Water backs up along the gutter and spills at the lowest point.
The underground connection beneath it is blocked, so water rises back out of the base. The line has to be cleared from below with a jetter.
This page covers clearing downpipes and their stormwater connection. Gutter replacement is a separate service the owner is confirming for this site.
Leaf guards on the gutter outlets and a clear of the pits before summer make the biggest difference on blocks with trees.
Do not let it sit through another storm. Call 1300 568 203 or book online for a clear that reaches the outlet.
