Water Hammer In Kitchen Faucet
Hello,
Have the typical single-handle Delta faucet in our kitchen. Has recently in the last few weeks developed a water hammer when turning it such that the cold water is put on. Water hammer only when turning on. So, I replaced the two springs and rubber "top-hat" gaskets in the faucet that contact the ball. Still have the water hammer. Any thoughts on what might be the problem, and what to do about it other than replacing the faucet with a new one ? Thanks, Bob |

I would take a look at the cold water supply from the connection to the faucet to the main supply. Look for a loose or missing support. Try holding on to both the hot and cold water supplies under the skin while someone turns the cold and the hot on and off. Follow the vibration or the pipe to the source. You will likely find a loose hanger or some sort of mechanical defect. If it is water hammer replacing parts of the faucet will not help, you need an arrestor or to dry out the one you have, but that you should only hear when you turn OFF the water not when you turn it on. |

Thanks, Bob I have a similar problem with a 4 month old LDR washerless double handle model 012 3400 Kitchen faucet with spray. http://www.ldrind.com/Index.html The hammer in this case is in the spout diverter valve as may be for the OP. If hot or cold water is turned on water flow through the spout is interrupted as the faucet goes thump thump. When the spray is pressed and hot or cold water is turned on there is one small thump and the water flows freely through the spray. Removing the spout and manually plugging the top and rear hole in the spout pipe, no thump. LDR does not list a replacement diverter valve for a kitchen faucet, IMO there must be one in there.

The cutoff valve under the sink may be the culprit. First make sure the valve is turned all the way on and see if this fixes it. They should be all the way open or closed, never in between. I had a water ammer problem that drove me nuts for nearly a year and found there was a valve hidden in the wall. The hammering started any time the water down stream from the valve was turned on. The noise didnt sound like it was coming from anywhere near the valve. The only way I found it was with the help of a neighbor who was there when the house was built and he remembered the valve in the wall. Jimmie |

Thanks Jimmie...Google search brought me here. After dealing with water hammer in one bathroom faucet for over a year, I just realized the valve was only on about a quarter turn. With it all the way open/on, problem solved.

With it all the way open/on, problem solved. Depending on the type of valve in question, if you have opened it all the way, you should now close it about 1/8 of a turn, maybe less. You want to have some play in both directions. If the valve is fully open up against the stop and it jams up due to corrosion, you may have trouble closing it. The best practice is to open a valve all the way and then close it slightly, maybe 1/8 of it's full travel, to ensure a little play to the open side. This applies to most gate valves and angle stops, not necessarily ball valves. |

Thanks, Bob Do you have a water pressure regulator on your house water supply line and has it stopped functioning and do you know what the water pressure for your house is? |

Why would it only happen when opening the kitchen sink faucet to draw cold water? If it were me, I would buy a "mechanic's stethoscope" for about $15 at any place that sells mechanic's tools. http://www.americantechnology.co.uk/...4006-120-p.jpg Touch the steel probe of the stethoscope to the cold supply line while a helper opens the faucet and confirm that the noise is coming from the cold water pipes, and not actually from the hot water supply piping. I'm wondering if you have crossflow through that faucet, and by opening the faucet to draw cold water, you're shutting off the flow of hot water through the faucet body, and THAT's what's causing the water hammer in the hot water supply piping? With the mechanic's stethoscope, you can move upstream of the faucet to hopefully find the section of pipe that's moving and bouncing off the nearby studs or drywall, and secure it better. For $15, it's a very handy tool to have. Last edited by nestork : August 31st 13 at 08:08 AM |

I realize this is old! But this thread lead me to the conclusion. It is air in the side sprayer hose causing the diverter to quickly surge to the hand sprayer while the air inside the hose is compressed to equal the. water pressure. I had this same problem, one of the responses nearly had it. Release the air from the sprayer and problem solved. -- for full context, visit https://www.homeownershub.com/mainte...et-360025-.htm |
