Pipes Banging badly since Water Company installed new pump

Help. Ever since the local water company installed a new pump locally (water pressure at outside hose faucet is 80+) I get banging that starts at the water meter (in the laundry room) and spreads. Wall shakes; dining room chandelier shakes; now sounds as if the strap in kitchen ceiling broke. Sounds like I am being invaded by giants with giant hammers.

Water company says they can't figure out it is their fault nor what the fault is but last week as their trucks went from hydrant to hydrant I got banking. Just got two lound ones; nothing was being used. Worrid that my house is at the end of a loop.

They installed a new meter as a precaution even though meter was fine; still getting banging. Am so scared of a large repair expense.

Before I go through the expense (on Medicare) of a plumber putting arrestors on washing machine (now causing banging) does any one have an idea of what is going on?

Thank you.

1. That pressure is a bit high, normal household pressure should be about 60#. Sounds like you need a pressure regulator to be installed.
2. The anti-hammer device at your water meter is water logged. Usually a piece of verticle pipe 2-3' long with a cap on it, at inlet to the house. That pipe is supossed to be full of air and acts as a shock absorber. If it becomes waterlogged, Which happens over time, no air cusion.
