Poor service
Less than a week after install, it leaks more than the original. When I ordered the replacement parts the customer service personsaid they would email a diagram for installation. None was sent and I can't find the instructions on the website. I just want to see the schematic for how it all goes together to see if that might explain where the leak is coming from. It should not be this hard to find help.

Breaks on a regular basis
Just like clockwork, every year or two I have to replace this part, the lift rod, or some related part of the roman tub assembly. For Delta's products to be so expensive, they hardly seem worth it. As soon as I can afford it, I will be replacing the entire tub assembly with a different brand. In the meantime, I'm back again, ordering this part.

Stripped threads
Stripped threads in diverter valve assemble where lifter rod attaches. Same as everyone else. These are not cheap faucet sets. I’d certainly expect higher quality and design.

Diverter valve
When I got it there was a small gap on the plastic on the bottom. I needed to get it replaced so I put it in. It works but it allows water to come out of facet. Should have returned it but because of circumstance I needed to get it in.

Poor quality
Having the same issues as everyone is, the lift hand to the diverter is stripped and pulls right out. Poor design. And 70 dollars to fix is very upsetting.

Weak design
I agree with the other reviews. Less than 2 years and stripped out. It barely gets used, can’t imagine buying another.

Threads stripped.
Faucet was repaired in January of '23. It's may of '24 and after trying to deal with it for months, this faucet has stripped the threads off the lift knob again. I saw a recommendation to cut the spring so I might try that. 70 dollars to be able to turn on my shower in a year and a few months. Very defeating feeling. Especially for someone new to disability.

Bronze threads strip out too easily
I agree with Allen that there is a design flaw with this product. That bronze threaded sleeve that connects the valve to the finial is not robust enough. The threads on this piece have stripped out on mine as well. Other than that the product looks and functions great.

Q&A
How does the wand hose attach to this?
Thank you for your question, Patrick! I apologize for any confusion and we would be happy to help. The RP40668 diverter assembly does not connect to a wand or hose but rather screws into the valve body of an R4707 roman tub rough-in valve. Please contact us if you need further assistance.

The rod that turns my tub sprayer on has pulled out all the way, it does not work at all. Do I need a new rod or a new diverter? It's 3 years old.
Roman tub set up with sprayer
Hello Monroe, Thank you for your question!
In a situation such as yours either the lift rod, diverter or both has stripped out. I would suggest replacing both items.
Best regards,

We have an 8 yr old Danze D215000BT Roman Tub faucet. The handheld sprayer no longer will flow?
I have removed the middle valve assembly and checked for plugging, but there is none. It appears that there is no water entering into the sprayer hose. Would this diverter valve be the cause?
Hi Dennis, Thank you for your question. Danze is a competitor's product. We do not recommend using Delta parts in other brands.
Thanks,
Dave

Is the delta diverter value assembly - R4700 the same for all roman tubs?
I pulled my out and it looks like the R4700 but I am not sure of the model of my 10 year old delta facet.. I am hoping delta only mady 1 type that looks like this.. possibly length may be a difference?
Hi Manuel,
Thank you for your question! The RP40668 will fit on any R4700 or R4707 deck mount Roman Tub Rough-In Valve.
Best regards,
Jon

I have a brand new roman tub faucet and it is leaking around this diverter stem. Should I replace it?
Hi, Wesley.
Thank you for your question. If there is a leak around the diverter stem, we do recommend to replace the diverter assembly.
Best Regards,

How to remove this product?
I have a replacement valve and can't access the assembly. I have removed the actual faucet and see the old valve coming out of a brass tube, but it seems stuck. I look under the tub and see the assembly down there, but it is all wired together and doesn't look like it can move either direction. Is there a trick to removing THIS PIECE SPECIFICALLY?
Hi Jon, Thank you for your question. Once the roman tub spout and lift rod have been removed there is nothing mechanical holding the diverter valve assembly in place. The diverter will slide out of the valve. Mineral build up may cause the diverter to stick in place. Pour a 50/50 solution of vinegar and water around the diverter into the valve body and allow the solution time to break up the mineral deposits. This process should allow you to more easily pull the diverter from the valve assembly.
Thanks,
Dave

Hi, Is there a DIY video (or some instructions) on how to replace the diverter rod ?
Thank you for your inquiry, Krys! Unfortunately, we do not have a do it yourself installation video for removing or installing the RP40668 diverter. To replace the diverter, you will want to first turn the water off at the supply valve. Remove the spout assembly by unscrewing the set screw that is located on the back of the tub spout counterclockwise. Once the set screw is removed, the tub spout assembly can be lifted off. Unscrew the diverter assembly and screw the new diverter assembly into place. If you should need more assistance, please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST. You may also email at customerservice@deltafaucet.com.
Best regards,
Tanya
