Default Water hammer???

When I run the spicket in the head sink, mainly the cold, it squeels like mad until I open it up further then sounds like a jackhammer coming from the faucet until I run it at full pressure. I have already unscrewed the facet head and cleaned it and ran the water with the facet head off and it still sounds terrible. None of the other faucets do this. What the heck?????
I have a 2001 2500 scr. All the other faucets run smooth hot and cold only the cold faucet in the head.

Any thoughts appreciated.

The pic looks like a supplemental duct heater to me....
Anyway.
That doesn't sound like water hammer - that occurs when a valve is quickly closed causing a hammer effect due to stopping the momentum of the water quickly.
Are the lines / tap set all good - no kinks nothing partially pluggin it? Check to see it is all clean through the whole thing.

That sounds like air in the lines.

air in the lines....let the water flow out the furthest from the pump...once it's flowing ..then go to the next one..check the connections at the tee's and the pump to ensure they are seated properly...may have to remove them and reset them to get them to seat properly...

If this is only occurring on the faucet in the head, then I suspect there is an airleak right at the connections for that specific faucet. Is this a Whale faucet? That is what I have in mine and mine acts very similarly. However, once I've turned it up all the way and purged the lines, it goes away. I even have an issue where I turn on the faucet and no water comes out at all. sometimes I have to turn on the hot side or the cold faucet in the galley to get the cold in the head to work. I suspect it is a connection that is slowly bleeding and introducing air. A constant bleed in the line, could account for why yours never goes away.

If you can, try pulling the faucet, then replacing teh connections on the water lines to just that faucet. Even try replacing the faucet (even if only temporarily) to see if that resolves the issue. It could be the mixing valve itself that is causing the problem. I can tell you that the behavior and sound in mine is identical when I run the water tank dry and have to re-bleed the lines.

Install an Accumulator Tank:

This would get installed after the pressure pump.

Same issue on my 3000...
Does this happen on both city water as well as onboard tank/pump?

Mine was solved when I replaced the water regulator (pressure was too high) and replaced the valve assy in the faucet. It was a combination of the washers being worn out and the pressure that cause the vibration in the valve.

Default My head sink (Whale) is hammering - as is the platform shower

Hi all - I have an 2001 3300 SCR - the galley faucet seems to work fine and runs smooth. But the bathroom sink hammers and shakes on cold. So does the simply swim platform hose shower head. I went into the engine compartment while I had someone inside try both - you can hear this tapping/pulsing sort of all through the engine bay, but oddly, it did seem more centralized near the hot water heater.

I read that clogged screens in the faucet outlet can perhaps restrict flow, then perhaps the pump thinks you're trying to turn it off, but gets confused, so just goes on/off?

I'm not sure how much fresh water I have in the tank at the moment.

Any ideas?

Since the galley faucet doesn’t do it I doubt the water pump is the issue. I would first inspect/clean the aerator for the other two to see if it makes a difference.

On mine, I found it to be the seals in the faucets. Does the hammer go away when. You open one of the all the way? Also are you on city water or using onboard tanks/pump?
