The picture shows a full inspection chamber and that the drain needed cleaning. The culprit on this occasion were the infamous wet wipes which have a way of not going down the pipes and clogging up the flow of waste.
By using the 4000 psi jetter hose the blockage was cleared however it took 10 hours to do due to their being a back drop where the wipes had congregated and made a ball making it very hard to get through them and break them apart. With persistence they eventually dispersed and the customer had a free flowing drainage system once more but they will be ever cautious as to what goes down the toilet’s in future.
