Hoping somebody can help.
I own a 3 storey house built in the 1960's that has city septic.
When the middle floor kitchen sink is drained it pushes the water out of the p trap in the kitchen sink on the lower level. There is enough pressure to 'blow' all or most of the water out into the sink before it flows back down. I thought that the vent may be trapped and snaked it from the roof without luck. No other fixtures appear to be affected and they all drain well. This problem has only been happening for a few weeks so i'm not sure what's happening.
Should I just call a drain specialist??
Thx.
