Hi just an idea run the hot and cold water pipes in the attic next to each other touching if possible then wrap them in insulation together now go to the sink in the new bath room and install a recerculation pump and make sure it is on when the weather is cold.
Frozen hot water pipe in attic.
Pex won t ruin if frozen.
Work your way back from the faucet to allow.
Don t forget your labor.
Insulation will help maintain water temperature levels in the pipes.
Ring them out then wrap them securely around the frozen section of pipe.
Replace with freshly soaked hot towels every 5 10 minutes until the pipe thaws.
Do use the sticky tape to create a hermetic enclosure for the new pex water lines.
Otherwise a cold water line run a long distance through a hot attic can take several.
Yes insulating the pipe will help.
You can also consider using an attic heater if one exists in order to keep the temperature just above 0 c.
Wrap cloths dipped in hot water around the frozen pipe.
It s smart to insulate water supply piping exposed to freezing temp.
Put on rubber gloves and soak towels in hot water.
So if you have the cold water line sitting there in the attic all day with nothing running through the pipe it will still get pretty warm after a number of hours even with insulation.
There are no manufacturer guarantees it won t fail.
Pour your warm water onto the frozen hose valve until you can remove the hose.
Wrapping towels soaked in hot water around the pipe or using a space heater to warm the surrounding area can help it thaw.
Heat the area until full water pressure is restored.
Wrap the pipe in hot towels.
Throw salt sand or soil into the water you spill in the path.
Insulate pipes located in the attic and crawl space using pipe insulation even if the climate where you live does not often have hard freeze conditions.
Never use a blowtorch kerosene or propane heater charcoal stove or other open flame device and keep space heaters at least a few feet from the pipe.
The cost will run about 50 70 per foot.
Keep pouring hot water over the open valve until water begins to flow.
The best pipe insulation for your situation will depend on your home.
However insulation just slows down heat gain it doesn t cool anything.
Continue to pour warm water onto it until you can open and close the valve.
You can drain hot water from the water heater tank into a bucket then dip rags into the water.
Another idea is box the pipes in and run a heating duct to them.
Look to spend about 75 to 150 to insulate pipe in the attic of a 2 bath home.
