Delta Touch2O Drips Repaired

I bought a (returned) Touch2O faucet from Amazon. After installing the faucet, I purged the line out using the handle of the faucet using a clean white bucket. I repeated the purge until no more particles & debris came out. [Do not use the shut off valve under the sink. Thus still cause more calcium & rust to break lose.] After that, everything worked. Except for a very annoying drip. I called Delta Faucets & explained everything. They had me did some stuff. When nothing worked, the sent me another solenoid. 5 days later it arrived. I swapped them out & now I had a extra one. That is the one you see here.
New construction or renovation people. If they do not flush out the lines, before connecting any line make sure that there were no splinters in the open hole of the shut off valves. I found shall wood chips, sand, rust, & other debris. Thid must be why the original purchaser returned it.
After re-installing the original valve a few weeks ago, it is still working like a charm.
