Kitchen drain clogged back up when toilet and bathroom sinks run
We have septic tank. Ranch style house.
Have tried every chemical. Have snaked plastic kitchen pipes. Flushing toilet in bathroom to the left of kitchen and running water in the bathroom sinks backs up the kitchen drain but tub is not affected . Second bathroom not affecting kitchen drain. Water filter connected to sink and no problem getting filtered water. Cleaned once the hose to where filtered water comes out. Possible plugged again?
Where is the clog? Why should flushing the toilet backup in the kitchen sink? Water eventually goes down but running the water afterward slows the water going down. Water coming up in not sewage.It is the water in the kitchen pipes. I used a plunger once in one bathroom sink and in the kitchen. Could I have made the clog worse?
Thanks
