Hi guys,
I have a double kitchen sink that has been working perfectly for the 20+ years I've used it. Earlier this year, the chrome plumbing underneath basically disintegrated in the spot under the bucket in the picture. I quickly took a picture of it for reference, took it all apart, and replaced it with PVC. Everything seemed to work right at first, but we quickly noticed an issue. When putting a lot of water in the left sink all at once (such as filling a bowl and dumping it into the sink while the water is still running), the water would rather come up out of the right sink than drain down. It's not extreme, but definitely wasn't like this before.
I've included a before and after picture. I'm stumped, as it looks like nothing much has changed...the only thing I can see is 1) the tailpieces attached to the sink baskets are now longer, 2) the trap is slightly higher, and 3) the PVC s-trap is a slightly different shape than the chrome one.
Before:
After:
Before everyone says it...I know the issues with S-traps (siphoning and codes requirements). If the solution involves converting to a P-trap, then I'm all for it, but this sink with the chrome S-trap worked perfectly like that for probably 50+ years.
If a picture of the plumbing below the floor would help, let me know. It's a full basement with direct access to the pipes. The only thing I did down there was cut off the 1.5" copper 90 with trap adapter (going up through the floor/cabinet) and replaced it with a 1.5" PVC 90 with trap adapter (connected with Ferco coupling to old copper).
Thanks!!
