I have well water and the main pipe bringing the water from the well into the house had leak. The pipe was replaced with a new pipe about a month ago.
Since then, the water pressure has been dropping gradually. The well guy came in yesterday and he told me that it was the filter in the line that got clogged up with debris. I replaced the filter again - I had put a new filter after the pipe was replaced-- and pressure is better that after the pipe replacement, but not as good as before. The well guy mentioned that if the problem persists after replacing the filter, it might be the tank might gone bad and it needs to be replaced. He looked at the tank which is 4 year old and there is no leaks, no rust, no scratches, nor any signs that would indicate a bad tank.
My question is: Considering the tank looks in good condition, how does the reservoir tank affect the pressure into the house?
I am by no means a plumber, but other than having leaks, I don't understand the role the tank plays on the water pressure flowing through the pipe. Or is the well guy trying to pull a fast one?
