We had a Waterloo Biofilter system installed December of 2012, by Septech. The system was'nt needed until late summer of 2013. The system was not installed properly and there were many problems in which the Waterloo Biofilter head office had to be called. The person we dealt with from Septech was,Geoff.
Recently I called head office to mention an odour from the system that doesnt go away.
I was told that the there was something put into the system to cause it not to work. To the contrary, we have been extremely careful not to introduce anything into the system to cause a malfunction.
We were also told to tighten the lid. This did not change the fact that the system still smells.
I was also told that the grading needs to be completed. This is a sealed system grading is not an issue. Conventional systems are at the grade or typically below. I have had a conventional system for 25 years and you would never smell it.
Since we have had this system, I feell that I have to troubleshoot after paying 21000. The installer Geoff at septech is not interested in coming out, never gave us an owners manual and once he received the cash he had to be told to come back by head office to do a repair.
All in all I dont think paying 21000 for what is claimed to be a state of the art system and have it stink is what anyone would want.
In summary, do not hire Septech, and think twice about getting a Waterloo Biofilter..
