Our sink clogged this week which first led to the replacement of the U-shaped pipe directly under the sink (which was, in fact, cracked and when the clog got severe water actually flooded out of that pipe). However, with new pipe, sink still clogged leading to the replacement of an extremely old and troublesome garbage disposal. Guess what? Clog still there. Next step was a major snaking of all pipes running from the kitchen sink to the basement...no luck. The next step seems to be taking a close look at the roof vent on the roof connected to this sink because we've been told that a clogged vent can lead to this kind of problem. The actual clog occurs after the water runs for about three minutes. The sink just backs up. Running the disposal clears the water so maybe it is some kind of pressure problem caused by the vent. Advice, opinions?? |

You didn't reach the clog with the snake. Did you do the job yourself, or did you hire someone?
The fact that the water must run for three minutes to back up tells me that, first, the drain is running, but slowly. Second, the clog is far down the line.
A clogged vent (very rare) is characterised by a gurgling, bubbling sound when the sink drains.

Someone did the snaking for us, a handyman. He snaked the pipe from the kitchen sink down and then the corresponding pipe in the basement. When you say you think the clog is far down the line, how far do you mean? Also, why would the water drain when we turn the disposal on? Is it just because it creates more pressure? |

Please excuse my delayed response to your inquiry. I can't tell you how far the clog is from the sink, but if the water must run for a while before it shows up in the sink, it can't be close.
The fact that it drains when you turn on the disposal is strange. For lack of a better explanation, I would think that the extra bit of pressure has something to do with it.
Sometimes, kitchen sink stoppages are very difficult to clear. When a drain is packed with grease and other solids, the snake may bore a hole through only to have it close up immediately around the cable when it is taken out of the pipe.
Repeated snaking with the largest diameter snake possible, together with the proper drain clearing attachments, most often clears the obstruction.

Thanks for your response. The drain is now clear. After the snaking it still didn't work but the next day while I was playing around with running water it just started to drain through again for no apparent reason. Perhaps the blockage wasn't totally cleared with the snake but was knocked loose enough for it to flush through after some water running(?). When it started to drain the washing machine was also running and I thought it had something to do with the water draining from that flushing through the pipes but I was told it's two separate pipes. But wouldn't they run into the same pipe outside the house? Anyway, I appreciate your helpful responses. |
