I have rust buildup in the one inch pipe (hose)that runs from my well into the house. The hose that runs from the pump to the point where it exits the well is clean. The buildup is only from the point wherethe pipe (hose) exits the well and goes to the house. This is seemingly reducing water pressure. Is there a chemical means of cleaning the pipe?

"This is seemingly reducing water pressure. Is there a chemical means of cleaning the pipe?"

You are correct, it's cutting down on both volume and pressure.
There is no magic repair to a galvanized pipe loaded with rust. Replace the pipe with PVC. Good luck, Tom

I'm sorry you were unhappy with the answer. Perhaps this will help. http://www.eci-ndt.com/tb_c_09.htm
