“After trying all over my area, I couldn't find the part for the faucet in my older house. The part I needed was found on the first try on their website and ordering was very easy. It was after hours, but someone responded to my text right away. The part was shipped the next business day. After putting the new part in the faucet works better than it has for years! ”

The Sayco K1D-1116 is a tub and shower diverter valve stem cartridge designed to control the flow of water between a bathtub spout and a showerhead. It features a brass compression-style body, is approximately 4-3/4 inches long, and uses a 16-point broach spline for the handle connection.

Stop annoying leaks and restore proper water flow with the Sayco K1D-1116 brass old-style diverter unit. Designed specifically as a direct replacement part for vintage and standard Sayco two- and three-handle tub and shower systems, this heavy-duty brass compression stem reliably switches water between your bathtub spout and showerhead. If your current shower diverter is leaking, dripping, or failing to completely send water upward, replacing the worn-out valve stem with this exact-fit aftermarket solution saves you from a costly full-wall plumbing remodel.

“Just before an event, we had a 9 7/8" round drain cover snap in half. It was an odd size and Noel's was the only place that seemed to have one that would fit. We couldn't leave the hole exposed during the event, and Noel's was kind enough to make sure it was overnighted to us. Their effort was truly appreciated and the cover fit perfectly! I highly recommend them! ”
