I replaced my Gerber cartridge to stop water drip and now when the water is turned on it pours from the handle. What did I do wrong and how do I fix it? I did not replace the seat. Water is not dripping when turned off so that worked I guess.

Hi PGJ

This should be a simple fix. Remove the handle and you'll see a small PACKING NUT at the end of the stem (1st nut you come to...see image)...tighten this a 1/4 turn and then test to see if that fixed the issue (put handle on and turn water on). If that didn't completely fix the problem, tighten the nut a little more being sure to test every 1/8th turn or so to be sure you do not overtighten the packing nut.

That should be all you need to do...;)
