But I'm back home on Long Island come November. Then things can get shaky up there.

The 30+ year old brittle plastic fittings in my first TT proved otherwise. One frost: the kitchen faucet and the elbow near the city water connection had to be replaced.
Call me Paranoid. I know the brand-new tubing is much resilient and there are fewer fittings. So, I'll play it safe for now and not risk having to fix the water system come spring...
