You can resolve minor water hammer issues yourself through several straightforward DIY methods. First, drain your home's entire plumbing system by shutting off the main water valve, opening all lowest faucets to drain trapped water, and closing them before turning the water back on to recharge air chambers. Second, secure loose supply pipes with cushioned pipe straps. Third, install screw-on water hammer arrestors directly onto washing machine valves or under sink angle stops. Verification: Turn household faucets on and off rapidly to confirm the banging noise has been eliminated.
