External faucet replacement. DIY or plumber?
We bought a flipped home 9 years ago (lesson learned). The exterior faucet (a Woodford Model 19 frost-free sillcock I believe) has failed. The faucet handle spins freely which it didn't used to do before.
After pulling the rod assembly out I found the check valve separated from the rod and is stuck inside the faucet body. From my googling this appears to be how the faucet was designed to fail in the event of freezing to prevent a leak.

The faucet travels through a brick exterior and into the basement and is fed water through a PEX tube. Faucet assembly and pex tube are mortared into the wall for some reason.

My plan is to unscrew the faucet through the exterior, then once that's free, delicately chisel out the mortar in the basement around the pex connector. Then replace the faucet.
Is this something you think I could pull off as a home owner or should I get a plumber? I have time and want to learn so I'm leaning DIY I just don't want to make the situation worse.
