Where can I buy a water hammer arrrestor?
Q. Hello! I found out that I have a water hammer problem with 3 toilets in my house. When water fills the tank, I hear tat-tat-tat-tat from basement. I was thinking about installaing mini water hammer arrestor by the toilets. Where can I buy the water hammer arrestors? Do I need a plumber license to buy these things? Thanks!

Why am I getting water hammer in my pipes when no water is being used and the heating is off?
Q. This is a follow up to a question I asked a couple of days ago. The banging noise happens when taps are turned off and some of you kindly explained that this was water hammer and ways to cure this but I can't understand why I get banging when no water has been turned on and the heating is not circulating through the combi boiler. Can anybody help with an answer please?

A. Probably air in the system.The mains pressure is always there unless you turn the main stopcock off ,and this pressure is forcing an air bubble or lock along causing the hammering.If it does not stop if the taps are turned on then the problem is possibly in the central heating side of the water.You need to turn the central heating on and bleed the system..The other possibility is that if you have a small top up tank in your loft,which has a ball valve to control the water flow,this valve might be the problem .Also check the ball valve in your loo cistern.

How do I find out if the water hammer or knocking noise is coming from supply side or drain side?
Q. I hear knocking noise when I flush toilets and when clothes washer drains. There is no such noise when I shower or use faucets anywhere in the house. Is there a quick test I can do to determine if the noise is coming from re-pressurization of supply side? or improper venting due to clog or improper slope of drain pipe? I was thinking of flushing the toilet but holding up the floater in the water chamber. If water doesn't fill up the water chamber and I still hear knocking, would that be the drain side that's knocking? Thanks! The noise can be heard as soon as toilet starts to flush. It can also be heard while water drains from the clothes washer. There is no noise when the washer fills up with water again. And I don't hear the noise… [cont.]

A. This question can probably be answered simply if more information is given. Water hammer is caused by the closing of a valve. If this happened during the flushing of the toilette then it should be after the toilette has refilled. Similarly if it happens when the washer is running then it should happen during the rinse cycle when the water is being turned on and off automatically by the washing machine. Or when the washing machine stops filling. Hot water passing through a cold pipe whether it be the drain or the water lines can cause ticking sounds due to expansion of the pipe. More information is necessary to narrow down the exact cause of the sound. If it is water hammer there are water hammer attenuators that can be installed on… [cont.]

A. Water hammer is a function of flow rate and pressure and made worse with improperly supported pipes. It happens when a high flow rate is shut off too quickly. Try closing the toilet supply line (from the wall to the bottom of the tank) a quarter turn at a time -- followed by a flush -- to see if the change in flow rate shutdown changes the dynamics enough to prevent the hammering. If that doesn't work install a water hammer arrestor. See link below.

A. The most common cause of water hammer is indeed air in the pipes as most of the other answers have suggested, but there is one more potential source: taps such as on a shower that automatically control temperature by maintaining constant ratios of hot and cold water can be faulty, and "hunt" for the right ratio with the result that they hammer. If the water hammering only happens from a shower/bath faucet, then that's your problem. Replace the self-compensating valve insert.

A. Depending on how the house is plumbed, you may need to put them at every faucet. If the lines all branch out and every wet room is the end of it's own line, then it's a candidate for hammering. If it's plumbed daisy-chain fashion, you might get by with just installing one at the last faucet in the chain. Start by installing one at the faucet that's the main cause of the hammering, and go from there.

A. I agree with Canuck! It is water hammer! Turn the main water valve off, and open all the faucets, until all the water has stopped flowing, then close all the faucets, and turn the water back on. All water systems, NEED some air trapped in the lines. There should be some pipes in the attic, that extend vertically at the highest point, with a cap on top. These are called air chambers, and they trap a small portion of air, that acts as a cushion, when the water has been running and it is turned off. The water still tries to move forward, and when there is no air chamber, the forward motion of the water is transferred to the piping system, and if the pipes aren't secured properly, they start to rattle and shake.

A. The term "water hammer" refers to the effect when water is flowing through pipes and is suddenly stopped. The momentum of the water causes it to crash against closed valve, causing a jolt to the pipe. You may be thinking of a water jet cutter, which uses an extremely high pressure stream of water to cut through solid material. This works by putting water under thousands of psi of pressure and forcing it out through a small but high velocity jet. This jet moves so fast it can cut through solid metal. Often, small particles of grit are added to the water to increase it's cutting power. This method is becoming popular in a number of applications because it allows very fine cutting through very hard materials, and you don't have to worry… [cont.]

A. There are small tanks (about one to two gallons in size) that are make of steel with a bladder or diaphragm. The diaphragm breaks the tank into two spaces. One connected to the water line and the other is under air pressure. These are designed to be thermal expansion devices for hot water systems, but they also can serve as pressure dampeners to minimize the pressure surges associated with water hammer. Some plumbers try to use a very small spring loaded piston device to do the same thing but they are not very effective.

Water hammer question?
Q. I have been having trouble with what I thought was water hammer on my shower. The sound seems to originate from the shower valve itself, and echoes throughout the house through the pipes. When it begins, water flow is greatly reduced, but by turning the faucet off and on a few times, it will stop.

A. You know may be you have to much water pressure on the city side of the meter and it's a city problem. Just a thought, and I don't think water hammer is caused by air bubbles. Also a plumber won't cost $700 just to drive out and give you his opinion. If he doesn't do any work I wouldn't pay him but there may be something like a $80 minimum just for driving out.

Q. I have been having trouble with what I thought was water hammer on my shower. The sound seems to originate from the shower valve itself, and echoes throughout the house through the pipes. When it begins, water flow is greatly reduced, but by turning the faucet off and on a few times, it will stop.

Can water hammer rotate the cartridge in a shower faucet?
Q. I have a Moen single-handle Posi-Temp shower faucet. After replacing my water heater and turning the water back on, there was significant water hammer when I turned on the shower faucet. After that, the water is no longer off when the handle is at six o'clock; instead it shuts off at three o'clock. Turning it all the way counter-clockwise is no longer warm enough. Could the water hammer have turned the 1222 cardridge inside the valve? If so, do I just need to remove the cartridge, realign and reinstall it in the valve so that six o'clock is the shutoff position again? Or does the cartridge need to be replaced? Note that it is not leaking -- just misaligned.

A. No water hammer would not rotate the cartridge. But is it possible the attaching screw has become loose betweent he henadle and the cartridge? Also the hammer may have loosened up some crud in the valve body/cartridge. I'd pull it (carefully) clean and reinstall. Eric

Water hammer and what is the cause?
Q. I have seriously rough case case of water hammer in the lower level bathroom. It only occurs when the hot water is turned "on" by itself. If cold and and hot are turned on simutaneously or if hot is turned on after cold, no problem. If hot is turned on by itself, man, it's like a train is going by right outside my door. Wife is buggin. I have no peace. Can you help a brother out? If this is just a washer job, I'll try to tackle it myself. If I need hammer arrestors and the like, it's a plumbers job. Perhaps I need need to re-establish flow (tried b4;failed, perhaps not done right). My wife called a repair man who suggested a new hot water heater. My house is eight years old so you see what kind of criminals I'm having to deal… [cont.]

A. As one of the other answers suggested, if this is happening when you turn the water on, it is not classic water hammer. Water hammer - in the traditional sense - is caused when you have water flowing and shut it off very quickly. Why? Water has a density of approximately 8 pounds per gallon. When you shut the water off quickly, the decelleration is very quick which causes a spike in force (and also pressure). This force/pressure spike is what causes the pipes to make the sound -- not much different than if you were literally hitting them with a hammer (only it's the mass of the water inside the pipe). A water hammer arrestor is simply a tube in which a pocket of air is trapped which absorbes the pressure spike and dissipates the energy… [cont.]
