Delta Faucet Company.
Reviews and Complaints

I installed a delta gooseneck faucet for a customer and she has complained about it leaking since it was put in and we have replaced the cartridge 3 times so when we went to the customer's house for the 4th or 5th time we warrantied the faucet out and installed the exact same faucet. This was done on 08/15/2022. Replaced 04/26/2023. When calling the customer service line today 04/27/2023 the customer service agent would not send out a new faucet and wanted to send a cartridge which has been replaced 3 times and then wanted a video of the leak. I am not able to send that video. Won't be buying anymore Delta products in the future. Very upset!

Had a replacement tub to shower. Delta single knob shower handle was replaced a while ago. The cold water pipe on the manufactured valve body burst and caused several thousand dollars to a brand new floor. It cost 1, 300 for the kitchen floor. We have had to shut the water off to the house. I actually tried to shut the two valves off for the hot and cold water; did not work!
i was informed that Delta is the most leading in faucets. I am a bit upset because now we can not take a shower, nor can my elderly mother (75) walk through the kitchen due to the water damage and the floor that needs to be replaced.
I do not know if you need a serial number for this faucet but, if you do please ask.

I bought a shower arm from Aqua Glass and it was defective. It leaked. I tried to contact the company by phone and email several times. They have never answered or called/emailed back. No customer service at all.
