Last week I installed a brand new Kohler Tyne pulldown kitchen faucet K-R21415.

[www.kohler.com]

This is a typical install with a pulldown spray head, and the hose goes down into the kitchen sink cabinet and do a U loop comes back up and connects with a clip quick connect. There is a weight to be used to keep the spray head in place and this weight is two halves that are connected to the hose with two screws, and the instructions call for this weight to be attached 2 to 3 inches above the bottom of the hose loop.



Now this is a bit different from other brands, I have installed Delta and Moen kitchen faucets their weights are like a one piece donut with a larger hose, you loop this donut through the hose and it basically sits at the bottom of the hose loop.

After a week of very light use, the loop formed a kink at the bottom, see pictures.






I am a bit concerned, I think inside this hose is just plastic hose right? A kink like this will have a fatigue effect in my opinion.

I called Kohler and sent them a picture, their customer service says "nothing to worry about, but we can send you a replacement hose if you like", which I said OK to.

I am 100% sure this kink wasn't there out of the box, and it wasn't there during initial install, and even though the sink cabinet is crowded with supply hoses and valves, dishwasher discharge hoses, icemaker hose, garbage disposer, I took time to make sure nothing is in the way and inteferring with the faucet hose being pulled down and back (and after one initial try the spray head was never pulled down again).

My theory is this kink is caused by the position of the weight, but this position is what the instructions called for. I asked Kohler tech support and they said this is what they recommend.

What do you think?

I have never had this happen. To be on the safe side, I would install the weight further up on the new hose, 8 to 10 inches up instead of the 2 to 3 inches.
