Kitchen sinks won't drain at all
My double kitchen sink was a slow drain that has turned into a sink that does not drain at all. Help! If it is a venting problem where exactly do I look for a vent or an air admittance valve? These were mentioned in previous articles.. which is great if you know what and where they are! :) We tried running a lot of hot water previous and did get a sewer smell in the upstairs bathroom? It was very cold weather at this time?! anything you can tell me would be greatly appreciated! Thanks.. Nancy
