- Stuck floats. A couple of times the floats that turn the system off and on have become stuck. Usually the solution is to give the sump outflow pipe a shake and this frees them up.
- Build up of sediment. Every year or so we pull the pump out of the sump, wash it down, inspect it and empty any sediment that has built up in the bottom of the sump. The pump is not designed to cope with sediment so this is more of a precautionary measure.
- Pumps have a limited lifespan. Our issue with the pump was detailed in the last post
- Blocked Disposal trenches. This took a bit of effort to solve, but was very site specific. During the drought (years of very dry conditions) the ground surrounding our disposal trenches dried out to such an extent, it had set like concrete, and lost the capacity to absorb water. We would have had the same issue with any system of underground distribution of waste water. In these conditions our soils were just not capable of absorbing the required amounts of waste water quickly enough. We replaced the first few metres of the installed underground distribution channels with Plastic Domed Drain Material which had a much bigger capacity and was capable of holding the waste water long enough for it to be absorbed over a longer period of time.
