Placement of Water Knot

A few friends and I were TRing last weekend and one of them centered the water knot in his webbing so it was tight against the back of the tree he had anchored to. I pointed it out and he said that it helps keep the knot from loosening.

I was taught the opposite: keep knots running free from contact to avoid binding, friction, etc. He said that that is the case with most knots, but the water knot actually benefits from this placement.

What say you?

Yea, I disagree with your friend, keep your knots free from contact with whatever you've anchored too. It would seem as though the loading and unloading of the anchor in a toprope situation could actually serve to loosen a knot in this orientation, but who knows (anyone?, Bueller?) Anyways, regardless, a properly tied waterknot is in no danger of coming loose, at least in my experiance. But hell, if there's one thing i've learned it's that people do all sorts of crazy shit with their anchors, I've seen stuff from ranging from a running a toprope through a single carabiner to 2 idiots using a 2 ton hand operated winch as thier anchor (no lie). So you know, use your best judgement when you tie in.

cheers!

I keep knots as free from contact with rock/trees as much as I can. Another problem with having the knot resting on the tree is that it isn't easy to see, and reevaluate it, as the water know can come loose after weighting and unweighting it.

If you are using a wrap3-pull 2 anchor for it to be correct the knot will be against the tree on the side facing the pull. This puts the least load on the knot and transfers the most via the friction of the wraps. If you are using a differant style of anchor the knot should be placed with two considerations. (1) do not load it directly with a biner. And (2) place it where it will not foul other rigging in the anchor.

I'm editing to point out that this was stated above already Blush

In my opinion...

It depends how the webbing was going around the tree. If it was some kind of friction wrap (like a "no knot" or a "wrap three pull two") then having the knot out of the system like that is good. With these setups the knot can be in a place where almost no force is on it at all.

However if it was a single loop or girth hitch, I think the knot should be free from rubbing anything.
