I recently purchased a 70+ year old house. It has an old (10yrs) water heater, and old galvanized steel water lines. Today, the hot water pressure throughout the house completely disappeared. I went downstairs into the basement and looked around. I felt the pipe from the water heater and it was hot. However, it was only hot to a point. When it t's off to the different service points of the house the pipe is no longer hot at all. Yet prior to it t-ing off, the pipe is very hot (about 10-12 ft of pipe). If I wait a couple of hours, I will get a little trickle that lasts about 20 seconds. Then, no more water. Is it probable that my pipe is clogged just before the 't' and seeping, or is it more likely the water heater?

dangerous water heater? -------------------------------------------------------------------------------- my nat gas water heater which reads 'do not convert' all over it, has been converted to propane. what are the consequences of this? i learned of this because when i moved in, none of the gas appliances worked correctly and there were leaks. after a month i talked the landlord into paying for the propane co to send a guy over. he finished the conversions on the stove and heater, but refused to touch or light the water heater to avoid liability. i had to light the water heater myself, because i need hot water. my landlord knows about all this but doesnt care. so...what will happen?
