Blocked Drain South Yarra
We recently were called out to Melbourne Grammar School’s South Yarra Campus in Melbourne, to unblock a stormwater drain running under a building. When we arrived on site, we opened the downstream pit and found a large tree root intrusion growing in the pit and through the reflux valve that is installed on this drain, restricting the outlet of this 225mm PVC pipe to approximately 25%.
We setup our High Pressure Water Jet Truck and got to work unblocking the drain. Upon removing some of the tree roots in the pit so we could unblock the drain, it became evident that the tree roots were growing through where the pipe penetrates through the pit. We removed the reflux valve for better access to the drain. Next, we cleaned the drain with the High Pressure Water Jet Truck to remove some tree roots and debris from the drain and after several passes we had cleaned enough of the finer roots to see the main source of the problem – two approximately 30-40mm tree roots growing up the drain. Once we were able to cut these off and remove the bulk of the finer roots, we were able to free the root trail from the drain and remove it. Once we removed the 5m long root mass, we were able to give the drain another clean with the Water Jet to remove any further debris that was still in the drain. Finally we reinstalled the reflux valve so that the drain was again operational.
