Performed leak detection and was able to determine that customer did not have any pressurized water leaks. After further inspection we found that the water coming up through the bathroom tile was a result of then toilet leaking. Pulled toilet to replace wax ring and saw that there was a large amount it roots growing up between the toilet flange and concrete causing the wax ring to fail. Removed as many roots as we could and re set toilet with new wax ring. Highly recommended replacement of toilet flange and sealing up gap between the toilet flange and wax ring in order to prevent roots to continue to grow up around toilet flange.
