soapy brush's freezing up

I hve two procon pumps that are hooked up to the weep system. One pump runs hot water thru a set of white hoses that asre in the bundles in the sttic that keep things from freezing up there, works well. The other pump that comes on at the same time, runs hot water thru the soapy brush's, there is a pressure gauge involved on this function that reads about 50-60 lbs. For some reason this is not keeping the soapy brush's from freezing. What is the reason for this failure. One thing I have noted is that the hot water lines on this function do not feel as warm as the lines that heat the bundles in the attic ????? There is no leaking at the soapy brush's so I have ruled out line failure. I am wondering if the pro con pump is not circulating the hot water , im[eller failure ??? but then there is 50-60 lbs of pressure on the system ????? any body got some ideas. Thanks
Some day the sun will shine again :)

Doesn't hot water freeze faster than cold water? Someone told me this once, it has something to do with steam?

Hot water does not freeze faster than cold water. It's an old wive's tale.

I found this: http://message.snopes.com/showthread.php?t=36453

I think the wives tale is cold water boils faster than hot.

How cold is the return line?

You could have pressure, but no volume. Either inadequate volume or not a high enough temp could cause the problem.

Also, I don't know the configuration of the system. What's keeping the FB hoses themselves from freezing up? It might be thawed in the attic but wherever the heating lines are removed from the FB hose you have a potential for freeze ups.

Unless the temps are under 8 degress, you should not even need to use hot water for weeping! I simply use a dixmoor weepmizer, and it cycles the weep using only cold water from the city pressure (40-60psi). The cycles get closer and closer together as it gets colder to eventually running constantly. If you do not have a weepmizer, now would be a good time to get one. Make sure that your check valves have not failed. a bad check valve usually is the culprit on weep problems. http://www.dixmor.com/products/dx1000.htm

thanks guys as usually once one inspects closely and learns a bit he figures things out hehe. First of all this is a seperate system from the weepmise it simply pumps hot water thru the soapy brush wands in a loop system but mine is not pumping at all , as the pump is capoooot. I was confused becasue there is a pressure gauge on the system and it was reading 50 lbs, it should be 125 - 150 lbs the 50 is simply the well pressure :(
new pump on order.
As for the dixmore weepmizer,,got one and love it as long at the stupid temp sensor reads corrrectly, I will have to move it to a shady spot
ASAP as it reads hoter than it should when the sun shines on it on a freezing day.
Also the attic is kept warm by another procon pump runing a hot water line in the bundle in a loop. Pretty good systems if they would just be managed properly by a competent owner manager :( oooops thats me :)
Thanks again, you guys are more help that you know.

The WeepMiser has inpute for two probes, and it will read the lowest one. You can put one on each end of the building to eliminate your problem of sun shining on it.

Thats Great, I did not know that. Sometimes reading the instructions helps Hu :) Thanks again, will investigate this idea.

my weep is working right either. can one bays bad check valve screw it up for all the bays?

Probably not.

I instaled a new pro con pump and turned it on , it went right up to 250 lbs pressure NOT GOOD suposed to run at 125. I turned it of, I think my regulator is bad so I ordered a new one and will replace it romorrow. The soapy brush's are frozen solid :( WOW why do all these things happen in the winter haha. Like was I supposed to do the maintenance on it in the summer when it was warm :) wont I ever learn. First thing I am doing when it warms up is removeing the heat exchanger on the boiler and rodding it out :) and lots of other little itemes that cannt be done in the cold.
SURE I WILL :)

It's probably running at that pressure because all the lines it's supposed to be pumping through are frozen.

FIXED IT it was the pressure regulator on the bypass, stuck in the closed position causing the pump to run full pressure and kicking the motor into overload and shutting down. Simply device ONCE YOU FINALLY GET IT APART .
