We used garvins once a few years back for roots in the drain. they cleaned them out no big deal no floods until June 2012 they did a routine check and it was "oil and debris" cool they cleaned it out but not very well.. by October 2012 we needed it cleaned again. Turns out we were not under warrenty as they only give 30 days!!! Well we paid it!!! we needed it fixed!! Now here it is Valentines day 2013 (3rd time in 8 months) and the SAME THING happened again. I called them. They will not back up their work. We throw EVERYTHING in the trash we NEVER drain oil in our drain.. it seems to me that the first time they just cleaned it enough to get passed the warrenty time so it would clog up and they could get paid again. Well our landlord is going elsewhere and they have lost business from not only him but anyone he or we talk to.
