What tio do! Leaking Big Agnes Copper Sour 2p
Jun 6, 2019 at 3:31 am #3596471Mike PBPL Member
<p style=”text-align: left;”>I have an older Copper Spur from an REI garage sale. We had it in the AT for a long section hike last year. Unbelievably we didn’t have any rain. We’re getting ready to do the Colorado Trail in July. My wife and , so I’ve been waiting for a chance to set it up in the rain and I had that chance tonight. The rain was coming down hard and it rained very good here for about an hour and a half with some big wind. I go check it out a few minutes ago and there it is with about an inch of water at a low side of the tent. The rain fly at one point did pull away on the side of the leak at one of the entry vestibules.</p>
Thoughts? I assume Big Agnes is pretty reliable. Do I need a new tent or might it have been from the rain fly tent peg giving way against the wind? That couldn’t have been more than five minutes until I fixed it, but until then the wind was flattening the side against the inner tent rather than blowing it open and exposing. Has factory foot print.
Any ideas or suggestions welcome.

Be very confident in whatever fix you decide upon. It’s looking like an unusually wet summer in Colorado this year! Happy trails.Jun 6, 2019 at 11:50 am #3596496James MarcoBPL Member

It appears it didn’t leak, but the water was from wind driven rain entering when the vestibule was open. If you are worried about it, you can coat the fly with mineral spirits and silicone about a 20-30 to one ratio. Just brush it in well.Jun 6, 2019 at 5:29 pm #3596536JCHBPL Member
Set it up again, button it up as you would in a storm and unleash merciless hell on it with a garden hose. You will have your answer quickly thereafter.Jun 6, 2019 at 11:00 pm #3596582Franco DarioliSpectator

If you find that it is indeed the fly leaking and not water ingress from other reasons, I would suggest you get hold of a can of Atsko silicone waterguard. That will add 2 oz or so to the fly weight. If you do it yourself you could end up with several extra ounces.
Make sure the fly is nice and clean first.
Atsko also has a liquid version. More expensive but it will last longer.Jun 7, 2019 at 7:51 am #3596622Roger CaffinBPL Member

a can of Atsko silicone waterguard.
I do that every couple of years to my aging blue silnylon tent. Works well.

It probably would be a very good idea to closely examine weather it is due to water leaking thru the fly fabric or if the water is simply being blown in from the sides and small openings, and the fly doesn’t have enough coverage.
In other words, if the fly were a little larger and came closer to the ground, would it still blow through? Would extra guy points help?
And geologically speaking, UV will ultimately be the demise of a good tent fly – even on a tent that was well tended to. Enough days out under the sun and no amt. of waterproofing spray will help any more.
