Need to reroute sink drain
Hi,
Thanks in advance for any help on this - these forums are really a blessing.
My kitchen sink is backed up somewhere between the sink and the drain leaving the house. A nearby sink, toilet, and shower all drain fine. A plumber came out today and tried for a couple hours, with two different snakes, to try to unclog it - no luck. My house is 52 years old and it does not have a vent for the kitchen sink, only one for the main drain. So it can't be snaked through there.
The plumber said the problem was due to the way it was plumbed, using water fittings instead of drain fittings. I'm a little surprised it has worked for 52 years and just now clogged "permanantly" - We've only lived here three months.
His solution was to run a new drain for the kitchen sink through the wall to the outside and straight out to the main drain going to the sewer line. The house is on a slab so there's no crawl space to work in. The walls are adobe and a foot thick, so running a pipe through it won't be easy. The main drain is only 6 feet or so away, so there won't be TOO much digging to do. He also said he would add a vent line in the process.
So I'm wondering, does this sound reasonable? The plumber wanted $1250 to do it, but he said he coulf half that if I dug the trench, and when it came down to it I could probably do it myself (that's what he said). I think I could too, I've worked with copper and PVC pipes and it seems like a logically simple problem. I also have skilled friends that would help me.
Thanks for any help,
Jeff
