: i have a deep well that had all new parts replaced a couple of months ago. last couple of days when you flush the toilet or use the washing machine the plumbing in the house starts to shake and the pressure isn't that good. i checked the well and pump and its working ok. the outside faucet works fine too. a friend advised me that i might have air in the waterline somewhere in the house. can you advise anything else?
If you don't have air coming out of the faucets it's not air in the lines but you could be going into a dry well condition. This situation is not good for the pump, so get someone to check things out.
