BLOCKED SEWER

Attended property on 10/12/15 to rectify/clear reported blocked sewer. Sewage overflowed into unit 11 before our arrival and during our works when the unit above decided to use their bathroom.

FINDINGS/ACTIONS

-Searched externally for the sewer stack access point without success

-Laid drop sheets and prepared work area

-The cables got stuck in the sewer drain approximately 5.5m  downstream

-Used a metal detector to locate cast-iron access point externally which was under the shrub/tree

NOTE
