yes, It must be stuck open or there is not one in there. The mercury t-stats open up at 143 degrees and you will not have any flow out the tel-tel till it reaches that temp then it will open and you will get some flow. A lot of the time the water on the muffs coming from a water main is so cold that running a merc on the muffs the t-stats will never open. The best way to check them is to put them in a pot on the stove in water with a thermometer and heat them up and make sure they open and close. They only cost $10 each so I change mine bi yearly with the water pump impeller.
