Since part number RP21598 has since been discontinued, can RP25592 be used in place of it, instead? Or is no extender needed?

Asked by: Grandpa Phil
Hi, Grandpa Phil! Thank you for your question. The Delta RP25592 Diverter Extender will work with the Delta RP10799 Diverter. Best Regards, Rosanna

Has the hole at the back of RP10799 been reduced (perhaps to be low flow)? I replaced part; now tub & shower have about 1/2 the flow rate -- tub takes 20 minutes to fill! Otherwise, diverter does direct flow. Does the old RP21598 have a higher flow rate?

Asked by: Marcus
Hi, Marcus! Thank you for your question. The Delta RP10799 does not restrict flow. We recommend to flush the valve to make sure no debris is caught inside of the unit that maybe restricting the flow. Best Regards, Rosanna

I have a Delta 3H Tub& Shower assembly in my shower. I want to replace the “guts” and the handles. I’m thinking I need- 3- rp10799, 1- rp17451 and 1- h61 (set). Can you tell me if these are the correct items?

Asked by: Andy C
Thank you for your question, Andy C! If your 3 handle faucet is a Delta product and it was manufactured before 1990, then either the RP21598 and RP10799 diverter assemblies will fit the valve body. If your 3 handle faucet was manufactured after 1990 however, then the RP17730 diverter assembly is correct. The H31 Knob handle will work on the diverter stem and the H41 are the correct size for the hot and cold assemblies. Please contact us directly if you have questions or need further assistance. https://www.deltafaucet.com/parts-product-detail?modelNumber=RP17730 https://www.deltafaucet.com/parts-product-detail?modelNumber=H31 https://www.deltafaucet.com/parts-product-detail?modelNumber=H41 Best regards, Edward

3 handle 1976-era Delta faucet looks original. Diverter is shot. RP 17730 fits but is too tight. Broke extender. So, ordered RP 25592. Should I start over with RP21598 and RP10799?

Asked by: Grandpa Phil
Thank you for your question, Grandpa Phil! I'm sorry to hear this broke the extender but happy to help clarify the parts you need. The RP17730 is meant for newer versions of the 2800 series from 1988 to present and will not fit. From 1988 until approximately 1975 the RP10799 diverter was used and can be identified by its round end with a black seal. Any models earlier than 1975 would also have a rounded end but would have used a tan seal instead. This is for part number RP21598, which has since been discontinued. Please let us know if you have any questions or need further assistance. https://www.deltafaucet.com/bathroom/product/RP10799 https://www.deltafaucet.com/bathroom/product/RP21598 Best regards, Edward

I replaced the diverter in my shower with this diverter and it works great, but now my hot water is dripping, likely unrelated as it's an old house. Can you tell me the part number to order for the hot water knob valve?

Asked by: DonovanB
Thank you for your question, DonovanB! A Delta three handled unit will use the RP4993 seats and springs under both the hot and cold handles. Please feel free to contact us directly if you have any questions or need further assistance with this model. https://www.deltafaucet.com/parts-product-detail?modelNumber=RP4993 Best regards, Edward

WHAT IS THE DIFFERENCE BETWEEN RP17730 & RP10799 DIVERTER STEMS? ARE THEY INTERCHANGABLE?

Asked by: Thomas
Hi, Thomas! Thank you for your question. Both of the Delta RP10799 and the RP17730 Diverter Assemblies work for a three handle bath valve. The RP10799 diverter works for valves installed before 1988. The RP17730 diverter works for valves installed after 1988. These are not interchangeable as the RP17730 is oval and the RP10799 is round in shape. Best Regards, Rosanna

Why shower still leaks after replacing diverter with Danco part

What is the difference between the Danco Diverter (as well as another one I tried) and the Delta Diverter RP part number? I have had diverter replaced with two different parts that are supposed to fit Delta; however, my shower still leaks into the downstairs bath. If I purchase the delta diverter, will it quit leaking?!
Asked by: Paula
Hi Paula, Thank you for your question! We recommend using only genuine Delta parts. Other brand parts are not manufactured exactly to our specifications. The Delta part should resolve your issue. Best regards, Brandis
