Delta two-handle faucet. Turn on the cold water only, water seeps out from under the hot handle then the faucet spits for a second as though there is air trapped. Only faucet in the house that does that.

I know delta has a lifetime warranty, but I have lots of seats and springs, if that is the culprit. Just confused by the seeping under the opposite handle that's off.

Almost same thing here but the most used, old faucet CW side leaks a tiny bit when it's on, not the HW side like yours. Mine are segregated but if they were joined by a base plate, that base leak could easily flow hidden over to the other side.

Pretty sure they need a plumber (me tired of doing this tedious work + shopping the parts) to change those old guts/cartridges.

I'd take a short video and fill out the warranty claim on delta's website.

We had a high end Moen kitchen faucet that dripped constantly. They sent us parts twice, then mailed me a $500 replacement.

Already done, parts on the way. They have replaced our kitchen faucet and hand shower in the master bath previously. Their customer service has always been very good.
