I just found this great forum & have a question. I have a four year house & all 3 commodes are Jacuzzi. The basement commode periodically will not flush. It may have flushed fine yesterday & today it will not flush. It will resolve its self over night or a couple days later. Today I ran a closet auger thru the toilet. This didn't help. I also removed the toilet & ran a 25 ft snake through the lines. There was water in the bottom of the drain line, about 2 ft down where it elbowed into another line. There was no water in this approx 2 ft vertical pipe. I installed a new wax ring & reset the commode. It still will not flush. Is this a vacuum issue? I have no problems with anything else in the basement. I welcome any suggestions. Thanks in advance
