OK Brett Hundley Jersey , I know you want to grab the portable propane torch and fire up that frozen pipe in your crawl space. This is the most dangerous practice to solve this problem because an open flame in a tight space, coming in contact with wood, insulation paper, plastic piping & plastic wire coatings is a recipe for a disaster. Pipes and wires run through small holes in the framing and in vertical voids of the structure. The torch user can inadvertently send super-hot gases into these voids (condensing the gases which create a greater heating effect on the gases Kyler Fackrell Jersey , remember our thermodynamics from above). Unbeknownst to the torch user, a fire is started in this void out of their view and will race up vertically in the void. The prudent pipe unfreezer person resists the temptation to use the torch & confidently grabs an electric heat gun or hair blow dryer and patiently unfreezes the pipe. Be careful with these electric heat guns as they throw off substantial heat and if held close enough to wood framing members or other flammables can start a fire just like a torch. Keep a safe distance when operating these tools and refer to the operating manual for safe distance recommendations. Another safe method is to create a sealed cavity or space around the frozen pipe and add a low level heat source to this cavity for gradual thawing of the pipe. For example, if you had a crawl space that had a frozen pipe & you could somehow create a cavity around the pipe with no wind infiltration (somewhat sealed), you could do something as simple as adding a relatively safe heat source (a lamp or drop light) to this cavity which would eventually heat up this small environment enough to safely & slowly thaw the pipe.
Another safe practice is to wrap the frozen pipe with an electric heat tracer. The heat tracer will gradually thaw the pipe. The heat tracer would often times need to be fed by an extension cord from a more remote power source (outlet) What will happen if you just wait for the pipe to thaw naturally? Hmmm Jason Spriggs Jersey , that’s the gambling man (or woman) approach. I like your moxie & I can appreciate gambling as an activity as it’s very exhilarating when you win, but when you lose…not so good, right? One thing to consider and understand is what occurs during the freezing & thawing process.
Water freezes, and if you remember what we all learned in grade school about the qualities of water you will recall that water expands when it changes from a liquid state to a solid state. That expansion of water within a contained environment (a pipe) can cause the pipe to split. This splitting or cracking of the pipe JK Scott Jersey , or the pipe fitting, is the risk with a frozen pipe. Not every frozen pipe will result in a water leak but be aware that you probably won’t know if the pipe is leaking until the pipe thaws by, manually by heating it (heat gun), or if the environment around the pipe is heated (naturally or artificially). The water in the pipes are pressurized so one can imagine that once the thawing reaches a certain point the water will begin to flow rapidly through any break in the pipe or fitting which will leave you minimal time to prevent an even larger water damage condition. A safe practice would be to depressurize the affected pipe by turning the appropriate valve off. Which valve to turn off is anyone’s guess as every situation is different. You could turn the water main off Marquez Valdes-Scantling Jersey , which would be kind of a catch all safety measure as all domestic water pipes eventually get their pressure from the main water supply. However, the heating pipes have water within a contained separate system that will have boiler pressure separate from the water main pressure, if a heating pipe is affected, the water feed to the boiler will need to be shut off and the boiler pressure will need to be bled off before thawing the pipe.

LONDON, Sept. 1 (Xinhua) -- British Prime Minister Theresa May's three-day charm-offensive visit to Japan was premature, a leading expert on British-Japanese relations said Friday.
Dr. John Nilsson-Wright, senior research fellow in Chatham House's Asia Program Oren Burks Jersey , said the Japanese government remained cautious over Brexit because of continuing ambiguity.
"Any expectations that May's visit was going to deliver some positive announcements and singing praises were misplaced," said Nilsson-Wright, who spoke to Xinhua on the phone.
He said May's visit to Japan will be discussed in London later this month at Chatham House's headquarters which is to be attended by high-ranking figures from Japanese political and business circles.
The event: A Retreat from Globalism? Angle-Japanese Cooperation in an Era of Nationalism takes place on Sept. 18-19.
Nilsson-Wright added there had been some benefits from May's visit, particularly over security issues.
Britain's decision to dispatch the Royal Navy warship HMS Argyle to the Pacific would be seen as a symbolic gesture by the Japanese.
Sending the frigate to the seas off Japan is part of increasing cooperation on security between the two countries. Although talks in Japan focused on Brexit were premature Ty Montgomery Packers Jersey , Nilsson-Wright said any talks on bilateral relations would be welcomed.
But the inconclusive negotiations in Brussels between the United Kingdom (UK) and European Union (EU) would have been fresh in the minds of the Japanese.
Nilsson-Wright said, "The problem for the prime minister is in Brussels. The UK is not yet able to say what the future relationship will be between Britain and Europe. There is concern that the position of hard Brexit supporters could make life difficult, particularly with the question of access to the European single market.
