Hello,
I've been chasing down what I thought was water hammer but with no luck.
Symptom:
When I quickly turn on or off the cold water on either of my kitchen faucets (there are two, back to back in an island) I here what sounds like a light banging sound from the fridge. It sounds a bit like when I use the water dispenser (just not as loud). This also happens (but not as loud) when I use the water dispenser on the fridge
The Plot So Far:
Pulling out the fridge, I can observe the grey plastic water line "jump" when the cold water on any of the kitchen sinks or the water dispenser of the fridge are turned on of off quickly. (In the case of the kitchen faucets, it can be avoided by opening/closing the handle slowly). It seems that some of the noise is inside the fridge and the rest is the hose banging on the floor/wall/fridge.
The one on the left is for a washer.
The one in the center can be soldered onto a tee.
The one on the right can be used inline like for a lav supply or an icemaker line.
I've already installed a pair of Sioux Chief 660-TR1 (The 3/8 to 3/8 one pictured at bottom of above picture) http://www.siouxchief.com/B_Product_Detail.cfm?GroupID=350250 on the hot and cold lines of one of the sinks. It had absolutely no effect that I could see or hear. (Granted I didn't expect the hot water line to be related, but I did it anyway as I was already under the sink). I still hear the same sound with the cold water on either of the two kitchen sinks (the one with the arrester and the one without).
I also tested with the dishwaser which didn't produce the symptom (which makes sense, it's on the hot water line), and the cold water on the washing machine (which does cause the symptom, but quieter).
The washing machine is further away than the kitchen sinks are to the fridge. I wasn't able to get the symptom to appear from any other faucet in the house. I didn't have this problem before, but the kitchen was remodeled and these faucets are new Hansgrohe units (much much nicer than the cheapo builder model they replaced).
Is it Water Hammer?
Anyway, based on my forum reading so far, if it was water hammer it shouldn't happen when a valve is opened right? Just when closed.
If it is water hammer, the water hammer arresters are to be installed as near to the valve which closes quickly as possible. I did this, and it had no effect.
The fridge and the faucets are all new at the same time (complete kitchen remodel, though no pipes were moved. It is a PEX system in the slab. (Austin, TX) House build in 2005.
Help!
