New shower cartridge leaks
To try to correct a leak in my single lever American Standard shower head I replaced the ceramic cartridge. Because I was in a hurry I decided to by an immediately available cartridge with a diverter. I would then grind off the diverter portion that sticks out. All was find however the show still leaked. I thought the grinding operation may have effected the cermac parts inside and I then purchase the correct part . The bag containing the part was marked Ultramix & Bath and shower Cartridge 051337-0070A. All was quickly restored to normal and tightening the attaching 4 screws. The shower still drips - perhaps a drip every 10 seconds. What have I done wrong and how can I correct this leak. Thus far I have spent $50 twice for the parts which no success toward a solution.
