[QUOTE="joegrizzy, post: 3928212, member: 45524"] yeah i had 'em dripping hot/cold all faucets. didn't have tubs dripping, but to be honest i don't think i've ever done that. in the attic to confirm, they ran the pex lines just like....thru the attic. just laid up there. i'm not sure how they thought they wouldn't freeze, i have absolutely no way of regulating the temperature of that attic. my space heater is maxed out, i threw a breaker trying to run another one up there, switched to space heater and one 30' heater cable. the pex is insulated with wrap around foam except for the T fittings and random sections of pipe. after a few hours of the heater cable working, i can feel the pipe itself is much more malleable and there's a trickle of hot water coming. but yeah, i mean it could be like.....conceivably months before we get consistent temps ABOVE freezing so....this isn't going to fly. i could try more than just a drip next time, but yeah everything i'm reading suggest WHAT DO YA KNOW when they replaced the hot waters line they did not follow code. from what i can gather, if running pex thru an unconditioned space, it must be not just insulated, but ran UNDER the ceiling insulation. this lets the pex get more ambient radiant heat from the house and drywall, rather than....just hanging out in the attic where it would without a doubt freeze when the temps are single digits with negative windchill AND YOU CAN FEEL THE BREEZE INSIDE THE ATTIC. like there's no way. my pex lines are froze because of the routing of the lines, which were done in the middle of summer. has nothing to do with faucets dripping.
