The REAL win is having that cushion at all, even if life keeps poking holes in it. I did the same thing after my first 10k and realized it's less about the number and more about proving to yourself you CAN do it. That habit of brown bagging and selling junk sticks with you way longer than the cash does. Next goal becomes 20k and somehow that feels slightly less fragile than 10k did.

Ditch every tool you own that touches that pipe, because once you see the inside of the old galvy you will never want to patch again. I pulled a section out last year and it was basically a solid rock with a pinhole in the middle, no wonder the water pressure sucked. The $4,200 stings for a month, but then you stop thinking about it and just enjoy taking a shower without worrying about rust stains on your white towels. Plus you will save money in the long run on all those little repair calls and parts you keep buying. Honestly the only regret I have is not doing it five years sooner.
