I have a well that has worked perfectly. The system had an in line sediment filter that had become clogged. I shut off the water before the sediment filter. There wasn't a shutoff after the filter so when I took the filter off, water ran back down the line. I replaced the filter, charged the line again and now I have nearly zero water pressure at my kitchen sink... I'm assuming there is water in the lines that needs to be purged... do I just let the faucet run until??
