Everytime I turn on the water in my kitchen sink the faucet makes a knocking noise - any suggestions?

Answer 1

There is an anti-hammer device that can be installed down by the incoming water line. Available at Loews or Home Depot, as well as Your Local Hardware Store!

Answer 2

Before running out and doing an expensive fix, try this:

Shut off your water supply line. Shut off your water heater (temporarily). Drain the pipes as best you can by opening all the faucets, especially the one located at the lowest point in your home. Now, leaving the faucets open, turn the water supply back on. Then close the water faucets and turn the water heater back on.

Try the affected faucet and see if this fixed the problem. Sometimes an antihammer air chamber gets filled with water for whatever reason..

If the hammering goes away and stays away, then the water supply probably was interrupted at some point in such a way that the antihammer air chamber lost its air.

If the hammering doesn't go away, or goes away only briefly, then you have a problem that will probably require digging into the kitchen wall. Either you have a leak in the air chamber (possibly a simple pinhole that can be soldered), or you need to install an antihammer device, and reattach your plumbing to the wall stud.

Answer 3

It could be that you don't have an "Air Trap" installed on the line, it acts as a shock absorber to prevent the faucet from banging. I am sure you do if the Kitchen is the only one banging. it could be a loose pipe in the wall, or the faucet could have a cartridge going bad. If the faucet is several years old and has just started this I would either rebuild the faucet,or replace it.

i would say its sired, air in the lines.....there is a small thing a plumber can do to stop this, he can install a 4-6 inch tee just above the water heater and it will stop this........u can try going outside and turning on ur water hose and let it run and ur highest indoor faucet like upstairs if u have one and let them run for 5 mins or so........sometimes this will fix it as a temp. until plumber can get there...

Answer 5

that is thoroughly superb. What you're listening to is the a million/2 inch copper water pipes banging both adversarial to a joist in the basement or adversarial on your sink. What occurs is that those water pipes are lower than consistent rigidity so as that the water flows out once you turn on the tap. once you shut the tap the rigidity will develop extremely because it has no the position to freely flow to love at the same time as the tap is open. to that end, once you open the tap the rigidity is finally "released" and it motives the pipes to leap or bang adversarial to a joist or something. There are some decrease priced techniques to attend to this. What i ought to do first is to have someone stand in the basement or anyplace the "bang" is coming from once you turn on the water. maximum likely what you'll discover is that the pipe isn't properly supported or nailed down. by the years with countless hundred or thousand bangs that is conceivable that you'll destroy between the soddered joints, even if that is a lengthy shot. i ought to bypass to lowes or homestead depot and purchase some copper pipe strapping or some nailable pipe help brackets. The strapping appears like a "U" with 2 tabs on both aspect of the "U". you position the strap over the pipe and gently press it adversarial to a joist or something else and screw in 2 screws to carry it in position. that is major use screws (drywall screws are superb) as in case you take advantage of nails, by the years they're going to relax and also you'll listen the banging back. The nailable pipe help brackets look like somewhat of copper cord bent in a "U" and the records of the "U" are bent over with sharp factors on them. back, you merely slide the "U" lower than the pipe, take lots of the rigidity off and merely use a hammer to pound both pointed ends right into a joist. that is likewise major to apply copper coated pipe help brackets or copper coated pipe strapping as everyday galvanized or metal brackets ought to have a chemical reaction with the copper pipe and may reason the pipe to degrade and likely leak. Copper on copper gained't reason any issues. in case you do this in some places, you'll see the "bang" is going away. the different decision is that you'll call a plumber and characteristic them put in "air ballasts" which look like lengthy copper tubes with the ends capped off. this enables the air to obtain in those ballasts and neutralizes the bang that the pipe makes with suggestions from the air & water move out of the tap. even if, on account that maximum plumbers get about $40 to $70 an hour, i ought to attempt the different decision first. sturdy success!
