Delta Model 2530 dripping

[lemmon]

My Delta Faucet was leaking under the unit on the hot side about a year ago.
so I ordered the new valve and seat and spring. Replaced it and all good.
about 3 months later I noticed a drip. I determined it was hot side so I pulled it apart
and all looked good but there were some "crumbs" in the body so I flushed it out.
put everything back together and it was still leaking. cleaned it out again and put it all
back together still leaking. ordered a new valve, seat and spring put it back together all good
a few days ago I noticed it was dripping again BUT if I use it then turn it off then push the handle
"more" off or hold it off it stops leaking until I use it again. Im a brave amateur but this has me stumped
any insight I just ordered another valve and seat altho this time direct from Delta instead of quick after market
but the whole thing with holding it in off position will stop it from leaking doesnt make sense to me

TIA
Lemmon

Delta has lifetime warranty, but the faucets are darn cheaply made.
Not much to do, if parts are replaced and everything is installed tight, then it is just a product failure and normally covered.
I've had a few new faucets defective out of the box, trust me on that.

Thank you

Don’t use aftermarket parts.

Make sure you install the parts correctly.

If there’s trash in your water, it’ll keep happening. Consider a filter.

I do have a whole house filter but I still get these crumbs.
Like black or dark gray disintegrated rubber crumbs
from time to time
especially the hot water

the sink was fine for the first 6 or so years before any issues

Thanks

You might have stainless braid rubber hoses or black cloth over rubber water connections to your water heater. It may be coming from there.

As recommended above, I have had best results using OEM Delta parts in my faucets, plus, as mentioned, they come with a lifetime warranty.

It might be from those hoses if the problem is in the hot side. But I’m not sure……..

Maybe granules from a carbon filter? Is your filter carbon? If so, is it granular or a solid block?
