I replaced my 1700 Delta shower cartridge with a new one from the company. I replaced it and now a week later it is leaking again. Did I do something wrong.

You may have dirt inside the valve, shut the water to the shower remove the cartridge, turn on the water for a few seconds to flush out all the debris and install the cartridge check it out, Thanks.

Leaking at the handle or dripping from the shower head?

Yes, where exactly is it leaking from.

Leaking from the water spout.

It sounds like you have debris (dirt) inside the valve follow as I stated in my post #2, if that wouldn't help call Delta to send you a new cartridge for free no charge to you, good luck.

It is not always clear in the instructions but most of us grease the cartridge and sleeve with a small amount of silicone grease or plumbers grease, make install easier and increase the seal.

Yep excellent advice Bob, Thanks.
