Welcome to JustAnswer, I will do my best to help you solve your problemThe frozen section could be concealed in a wall or ceiling.There are 2 ways to deal with this.Either get a salamander heater (portable job site heater) and raise the temp of the space where any of the piping might pass throughor use a pipe thawing machine if you have copper tubing for piping, which is essentially a modified arc welderCustomer :most of the pipe are exposed in the basementRick the plumber :same answerif all the piping in the loop is accessible you could use your torch to thaw it outbut you need to very carefully play the torch along all the piping in the loop not just the fittingsCustomer :that's what i did and that why i came to this siteRick the plumber :did you heat all the pipe in the loop?Customer :yes all that i could reachRick the plumber :then you can't get to some of itCustomer :just the pipe that goes threw the floorRick the plumber :Then my original answer applies. Those are your only optionsif this zone is on the first floor try playing the heat on the piping above the floor as wellCustomer :some of the pipes go along the foundation and up along the foundationRick the plumber :same answermy guess would be that your frozen section would be along the foundationtry heating up this area with your torchjust keep the flame away from anything flammableCustomer :yesterday i open the drain valve on that zone and some hot water came out the stoppedRick the plumber :if there is craft faced insulation get it out of there before you heat that areaif you opened a purge station and the water stopped then you probably have a frozen lineCustomer :should i leave it open when i do thatRick the plumber :it doesn't matter but leaving it open will let you know when it thaws outCustomer :because it is after the pumpRick the plumber :same answerturn the thermostat way down on the frozen zone so the pump won't runCustomer :which has a valve between the pump and the drain valve if i leave the valve open it will come out but if i close it it will come out the stopRick the plumber :if you leave the valve open you are getting water from the boiler. if you close the valve the only water that can come out of the drain would be through that loopCustomer :but what is going to push the water thought the pipe if the pump is not onRick the plumber :the pressure in the systemyou should have at least 10 psi on the systemCustomer :well let me try it thenit didnt workRick the plumber :what didn't work. I gave you several options. Did you try them all?Customer :i put a space heater in the dining room witch has no heat the living room has a pellet stove so i think that is why i got the frozen pipe in the first place because the heat controls both and the dining room and living roomRick the plumber :you need to put heat in the basement, that's where the frozen pipe probably is.Customer :you told me that you have to raise the temp in the room that the pipe areRick the plumber :there are pipes in the basement ?Customer :yesRick the plumber :".... get a salamander heater (portable job site heater) and raise the temp of the space where any of the piping might pass through"Customer :that is not going to work in my basement becuse it is filled with stuff and the fire marshell will have me for lunchRick the plumber :then your only option is to wait for it to warm up or hire a plumber with a pipe thawing machineonce it's thawed out it would be a good idea to fill the system with anti-freeze so this doesn't happen again.Customer :how do you put it in the systemRick the plumber :antifreeze is pumped in under pressureyou will probably need a plumber to do itCustomer :this why i came to this site so that i didnt have to call a plumber this is the first time useing this site that my problem was not solvedRick the plumber :All I can do is propose solutions.
