          Flush it

          This product has worked for us it took only a couple of days and the smell disappeared this saves me $1000 to get the tank pumped
          The delivery charges of this product were way to high it came by courier when it could have been express posted for 1/5 of the price

          Thanks for the feedback Justin! We are glad that your problem has now been resolved. The delivery charge depends on many factors such as the type of courier service and the destination of the item.
