“The cartridge in my kitchen sink broke last week so I've been without that sink for a whole week. I ordered a replacement from Noel's, which I could not find anywhere else and it worked perfectly. Thank you! You saved me! ”

The Kohler 1131496 is a genuine dual-flush canister valve seal designed specifically for Kohler dual-flush toilets that feature a top-of-tank twin actuator button. Over time, water chemistry causes the original seal to warp or blister, leading to a slow, ghost-flushing leak into the bowl. This part is the direct solution to stop that leakage and restore proper flushing efficiency.

“The vacuum breaker on my outdoor spigot failed and Noel's Plumbing was the only placeI could find that had the appropriate mfr. part. I sent a text with photos on Wednesday evening to make sure the part I found was correct. In less than 2 hours later, I had a reply confirming it was the correct part. Placed my order that evening and received the part on Saturday afternoon (about 2.75 days) and my plumbing issue was resolved! I highly recommend - I really appreciated the prompt and pleasant response. ”
