I've been scratching me head on this one...I've replaced the DW tailpiece directly off the sink drain twice already. Top Hat Washer as well.
17GA tailpiece . Noticed this again, corrison outside tailpiece - must be coming from the joint between sink drain-tailpiece.

What gives. I think on this round, I'm going to put some dang tape and dope on the nut, just because for good measure

Off the Kitchen sink drain, it's leaking on the DW tailpiece off of it (17awg brass).
Didn't pick up on it till now, but it's got quite a bit of crud/corrision from whatever is slowly leaking from use....
And I've replaced it 2X in the last 5 years as a Wild Guess ? Last time being maybe a year to 16 months ago ?

I gotta do it again, so either I'm not tigheting it enough, or I need to -dope- the threads to let me tighten even more or like TR suggested and this what I am thinking, is don't replace with brass but poly

If the leak is coming from the slipjoint connection, then a poly won't be able to be tightened more than a brass/steel nut would. Maybe a softer washer would squish and hold torque better and potentially fill any gaps in the mating surface?

Use compatible metals (avoid mixing brass & steel).
Seal it up! Teflon tape + dope on the nut threads.
Upgrade the washer: high-quality rubber or double-washer.
Clean regularly: remove corrosion with vinegar/baking soda.

Remember to check for rough edges, use the correct length, and avoid overtightening.

Still dont really get it but a slip joint washer I like are those soft blue rubber ones. This aint rocket science take it apart clean it alighn everything properly and try again sometimes I just tear all that crap out and throw away and for around 6 dollars rebuild it after all all time is money.
