Excellent Service and Support?

Comments about DELTA FAUCET Delta Single Handle Valve Delta Cartridge (RP50587):

I contacted Delta based on reading other reviews. To my surprise, the reviews were spot on. The support person was very helpful and best of all Delta shipped the replacement part for free. The replacement went smoothly and my kitchen facet is working normally again. I really appreciate the companies support and hope they continue to provide such support. I would highly recommend using Delta's products.


Replaced under warranty

Comments about DELTA FAUCET Delta Single Handle Valve Delta Cartridge (RP50587):

Original started squeaking and binding about a year in. Tried external wd-40 lubrication w/o success, lived with for several month, then after researching online found Delta would replace under warranty. New cartridge arrived in a week as promised (great customer service!), but came dis-assembled (?) w/o any schematics. Fortunately a good youtube video showed breakdown/assembly. Installation easy. Inspecting the old unit I found a small chip on the edge of the white ceramic disc which probably created the problem, so disassembly and re-lubrication with silicone grease would not have helped. Hopefully materials and manufacturing of the cartridge have improved so that it does last for the million uses that Delta advertises. Had forgotten how smoothly faucet operates when working properly!


Great assistance on replacement parts; lifetime warranty

Comments about DELTA FAUCET Delta Single Handle Valve Delta Cartridge (RP50587):

After reading reviews here, I called Delta customer service, and received prompt and straight-on help (from Clint) in ordering a valve assembly replacement cartridge. I also am having trouble with the faucet leaking, and have to put the handle in just the right "sweet spot" to turn off the drip. My contact information was on file from a previous Delta product, and the representative is sending out the part in 7 - 10 days at no charge. If I have future problems, all I have to do is call them, and they will help me again. I didn't have to give them info. on the Savile bronze pulldown faucet that I purchased three years ago-- my warranty info. is on file with them. The rep. couldn't have been more helpful, and Delta does stand behind their lifetime guarantee! Call them before trying to order a part on your own--- it will save you bucks!!! He also pointed out a helpful "How-to" video on their website for installation of the cartridge, titled: "How to replace a diamond seal technical cartridge."
