Hi All,

I have a delta 3578-DST sink and water was leaking out of cold handle. Thought it would be a seal and spring replacement and after taking handle/valve cartridge off I noticed I damaged the piece below the cartridge (pictured) that connects to bottom of cartridge and is attached to water line.

Delta is sending a new carriage but I asked about this piece and they weren’t willing to send just yet. Do any of you know where I can buy this piece connected to a water line? Don’t want to replace whole sink!

Thanks for the help

Delta would be the ONLY source, if even they have it.
I HATE it when they make you wait for a part to arrive, before calling back and wasting time again begging for parts, and then needing more, being sent more and THEN in the end they will send you a new faucet, which is what you need.
 
Darn! I thought there was a seat and spring under this piece and I think i made a mistake using the pliers to pull/chew it up.

You’ll need the entire rough valve now..
 
Yep, you ruined it. ✌️
Thanks for the reply! I feel like such a rookie being so aggressive but now I know what not to do on the next one.

There isn’t a part on the sink diagram for this specific piece. Do you guys know what it’s called? Seems like it would come on the water line already since it’s attached.

Need to know what to beg delta for next. Thanks so much
 
looks like to me the whole thing got pulled out. It shouldn't have. Get a new faucet. This model is discontinued.

Seems like this cartridge/valve is used in a decent amount of other faucets. Hoping they have the water line part?

highly doubtful. Did you take the supply lines out of the valves before you took it all apart?
 
Man I feel like an idiot! I pulled valve out and pulled up on plastic end valve assembly piece with pliers and lines were still connected.
