My house is on a well, which then feeds into a well tank. The water pressure in the house is good, except for the bathroom tub/shower. After spending a little time with it, it looks like the cold water is not making its way through the pipes, only hot (just in the shower and tub). I have a feeling there is a blockage of sediment in the pipes. Any suggestions on how to get this out (snake, chemicals etc...). I am going a bit crazy here trying to figure out how to get cold water into the tub and shower. I could also call a plumber, but I would like to be able to do it myself. Thanks to anybody in advance for their help.
