Water hammer after plumber replaced the washers
The single handle kitchen faucet never had the hammer until the licensed
plumber replaced the washers to stop a leak. What would cause this to suddenly become an annoying problem? The plumber is "slow" in returning to check out the problem. Thanks for any ideas. |

Thanks for any ideas. imo the new "washers" in the single handle faucet perhaps allow the faucet to shut off the water flow quickly & thus trigger the water hammer the "fix" either shut off the faucet more slowly, in a controlled fashion OR have the plumber add some water hammer arrestors at the kitchen faucet shut off valves cheers Bob |

So a suggestion. The new washers are doing what they are supposed to; shutting off the water firmly and completely. Whereas the older one were leaking/ dripping? However the proper way to operate the taps is not to 'snap' them off suddenly. Turn down gradually, then off. Also has any thought been given to why the washers were leaking? Was it neglect? Or just normal maintenance? Because they do wear out over timer, especially the hot! Also is the water pressure rather high, thereby contributing to water hammer if the taps are turned off too suddenly? Rather like pressing the brake on a car and expecting it to stop immediately and suddenly without any jerking or skidding! |

Rather like pressing the brake on a car and expecting it to stop immediately and suddenly without any jerking or skidding! I was referring to adding "real" water hammer arrestors; either piston type or diaphragm type NOT those silly, useless lengths of pipe above the angle stop. I was further assuming that no "real" water hammer arrestors existed in the installation. Small add-on / washing machine arretors could be easily added by the OP (if they are at all handy). Those pseudo arrestors (short pipe lengths above the shutoffs) do very little to mitigate water hammer even when first installed (or drained). Additionally they "water log" very quickly & lose even their minimal utility quite soon. cheers Bob cheers Bob |
