Danze long single lever cartridge with seat & springs

The product works, I wish they provided instructions on how to install with the hot cold lever. Spent an hour on the phone with customer service.

I have a Pegasus single handle shower valve from HD. Installed it a few years ago and just now it started to drip. Within a week the hot water was running so bad I almost shut the water off to the house. Having experience in plumbing I planned to change the cartridge and seats myself but couldn't locate the parts locally. HD will provide the parts for free but I had to send photos and they are researching what I need....it should only be a few days and meanwhile the water is running. Anyhoo, I paid the extra 3.99 and got next day shipping and replaced the seats, springs and cartridge in 10 minutes. All the parts were a prefect fit and all is well.
