@andrew_construction_: Today we installed a backwater valve because the existing house didn’t have one. The client decided to install it to help prevent future flooding. Since the drain was lower than the basement floor, we installed an outside backwater valve. Everything was done to code and with quality workmanship. Here’s a look at the process! @Drobot Construction Hashtags: #Plumbing #UndergroundPlumbing #BackwaterValve #Waterproofing #Drainage #PlumbingLife #PlumbingWork #Construction #TorontoPlumbing #FloodPrevention #HomeImprovement #Contractor #BuildingBetter #PlumbingSolutions #DrainRepair
