Not yours, although you may have to fight it.   The U.S. requires that electronic goods be sufficiently immune to properly transmitted RF.

Several years back Eaton ended up redesigning some of their circuit breakers because RF from ham transmitters was tripping them.

Another thought on these is water waste/cost?

Or for those of us out in the nice RF quiet Boonies,

Imaging you go somewhere say a vacation. And while you are gone for some
reason it turns on.

Many many people have just holding tanks for their waste from the house
imaging when you get home and your tank is full to overflowing and who
knows how much of the house is flooded?

Is this a Delta faucet?  I have one two and it also will come on during a thunderstorm.  I tried using ferrite on 
all of the leads, and wrapping as much as I could in tinfoil to no avail.  We are no longer using the touch 
"feature". I have also heard of problems with the motion or iR sensing faucets too.  Friend had a cat 
that jumped up onto the counter and turned on the water,  Chuck K9LC

CQ-Contest Reflector<cq-contest@contesting.com>  Subject: [CQ-Contest] RFI Faucet I do a lot of baking, so decided to 
purchase and install a new touch operated faucet for the kitchen sink in the ham shack.  It works great, allowing washing 
hands without messing with the faucet handle.  However, I recently discovered the faucet turns on when I transmit power on 20 
meters.  Also, my XYL decided she wanted one of these faucets for the main kitchen, and informed me that her faucet behaved 
erratically one evening when I was operating CW on 80 meters with 800 watts.Anyone know how to shield a touch faucet?  The 
model I have is Delta Faucet Leland Touch Kitchen Faucet.  It is powered by 6 AA batteries.  The battery pack is 
connected to the valve via a pair of wires about 3 feet in length.  There is also a single wire about two feet in length 
connecting the valve to the faucet.Thanks for any advice.73, Keith NM5G_______________________________________________CQ-Contest
