kitchen sink slow to drain
I have a sink which doesn't drain when large amounts of water are poured into the sink (eg. Dishwasher drains). The water will sit in both sinks for hours before draining. Once drained, you can turn on the faucet & its drains fine. I have read the other thread on this subject and tried snake-ing from under the sink (removed trap; which was not clogged). My snake is about 20 ft long & fits on my drill. I did this 2x. I have also snaked the vent on the roof & ran water down w/ the garden hose. All this did was fill up the sinks.
Do I need a longer snake? Any ideas? I will try the vineger/ salt/ baking soda fix...
Thanks for any replies!
