My approach is to use water to flush the sink pipe, and it works great so far
- loosen one of joint connectors of the sink pipe under the counter;
- pull your backyard water hose into kitchen;
- wrap the hose end with soft cloth and squeeze it to the sink pipe - on the side towards the main sewer pipe;
- make sure the wrapping cloth is tight enough to prevent water from coming out;
- turn on the water slowly to a high volume while using hands to hold the wrapping cloth to prevent water flow;
- normally, after 15-20 mins, the sink pipe could be unclogged;
- pull out the water hose stuff and re-connect the sink pipe;
- I usually turn on the hot water for another 15 mins or so, so that grease on the sink pipe can be flushed away as well...
简单得很,把底下的U管处接口拧开,用钩子掏出堵住的垃圾,再接回去就可以了。
