Replaced Moen faucet cartridge, still leaks

[TDR]

Moen kitchen faucet, 14 years old, dripping at spout for a few months, ran out of positions where it did not drip. Replaced cartridge following Moen instruction video () and other DIY videos. Very carefully triple-checked everything, repeated installation. Carefully aligned cartridge tabs. New cartridge is Moen brand 1225, exact match for original. Cleaned valve body thoroughly with toothbrush and flushed, twice. No apparent grit buildup there. Cleaned all parts before reassembling.

Still drips, in all positions. What am I missing?

Replace the cartridge again. This stuff is not perfect every time. Could have some trash stuck inside of the cartridge….who knows. Go back into it. That’s what pros do….

That’s why I rarely carry just one of a particular part on my van. I like to have a few just incase one is defective.

Thank you. On my way to shop around. Yesterday, Lowe's had only one in stock, despite their online inventory saying they had eight. Will follow up with the results.

Replace the cartridge again. ...

You nailed it. Replacement #2 working fine. Thanks very much for your help.

Glad to hear. Were they both Moen brand cartridges?
