We live in a manufactured home. We have always dealt with calcium buildup in our house. We had fine water pressure one afternoon we lost it all water pressure to the cold side in entire house. We still have hot water. If we are running hot water in one part of the house and the cold side is one then hot water water will come into the lines. We have tried to put vinegar into the lines to break up the calcium, but it hasn't worked. We tried to blow out the water lines but couldn't get anything to work. Right now I can't afford a plumber is there anything that I can do to get my cold water to work?

How old is your house? There may be just a few clogged pipes, or there could be many, but it sounds like you have a big problem in the main water line that feeds the house. I am assuming your toilets and showers are affected also. Am I correct? You would certainly have to pin the problem down.

Whole house blockage of every fixture would indicate a clogged pipe closer to you main shut off wherever that may be. How many baths, is there a laundry room? Or could it be a FROZEN pipe? Where are you?

Another important question I have If you are getting hot water from the cold side what kind of pressure do you get? I have to tell you that that is a different issue altogether since if you cannot deliver cold water, how is the hot water delivered through a clogged pipe?

Right now I lean toward a frozen pipe and heat is the solution if you are in the middle of a cold spell. Please clarify for me. I await your further information.

If you have hot water then you have cold water into the home up to the hot water heater (cold feeds the hot water heater to make the water hot). After the cold water feeds into the water heater will be the next place to start. Here, go to the water heater and determine the cold water pipe that feeds the water heater. Follow the cold water pipe past the water heater (and AWAY from the water meter) and find the next fixture that gets fed by the cold water... see if cold water gets to that fixture. IF cold water does not come out of the fixture in question then check the shut off valve at that fixture (or in the basement where the pipe is before it brances off to this fixture) for water flow. If cold water flows at this fixture continue "walking" the cold water line until you find the first dead fixture and start to look for a clogged shut off valve or faucet.

This takes some simple investigation, a little common sense and some basic plumbing skills, so give it a shot... it really shouldn't be too hard to figure where the issue starts given the fact that you have hot water, OK?
