I have a Delta T13 series faucet in my shower and tub that is dripping. I replaced the valve cartridge and it still leaks. Do you have any ideas what the problem might be?

Would this be your shower valve? (see image)

Yes

The model I put up doesn't use a cartridge. Now I need the model number of your valve. Regards, Tom

Yes it does the valve cartridg pat number is rp19804 according to the drawings you posted.

Did you flush the valve when the cartridge was removed?

If not remove the cartridge one more time, get some help turn on the water for a few seconds to flush out any dirt remaining inside the faucet, good luck.

It's not a regular cartridge. Regular cartridges, such as Moen, don't break down. As you can see by the drawing it's an assortment of parts. But the parts you shoulkd be interested are the seats and springs. I think john nailed it, Follow his instructions and don't forget to check the seats for any mineral build that might be there. Good luck, Tom
