Finish wore offOrdered the delta dorval faucet in the champagne bronze. It was a beautiful faucet, however the finish has worn off horribly. We have 4 other delta dorval faucets in the matte black that are mostly fine, but the champagne bronze looks terrible after only a short time.
Customer care was zero help. For the crazy amount these faucets cost the finish should hold up significantly better than this, beware.

Beatiful faucet with design flawI've had this faucet for three years. I'm on my third replacement (each one installed by a different licensed plumber) and the handles continue to leak from the top. Delta has been great but for a faucet that costs this much I have had to put in a lot of money just have them. At this point, I am just going to keep fixing them every couple of months (replacing the valves) until I find another faucet that will work with the set I have in my bathroom. Note: I had three bathrooms renovated with all delta products and this is the only one I've had problems with.
I think this faucet is beautiful, BUT there are only two reviews and neither is good. I plan to go with the basic chrome, but has the valve problem with the handles been resolved?

We are committed to supplying you with a quality product that delivers the expected performance. We are happy to help with any issues! The valve uses diamond coated ceramic parts to help reduce wear and potential leaks. The chrome finish is durable and will last the life of the faucet when cleaned and maintained.

Is there a way to disable the Delta Water Sense? We installed two of these faucets in our master bath and the amount of water that comes from the faucet is not sufficient to rinse a toothbrush.

Is there a way to increase the water flow? And is there a way to increase the ability to increase heat of the water?
Asked by: Brad
Hi Brad,
Thanks so much for contacting Delta Faucet Company!
Unfortunately, there is no way to increase the flow rate of this faucet. The only way to increase temperature would be by raising the temperature of your home's hot water heater.
Please reach out with further questions!
