I last went up the filthy five a few months ago. Entirely depends upon your risk/reward ratio. The bolts and hangers are bad by most definitions and some are more of the homemade variety. Some of the hangers have a tendency to flex slightly when loaded. I put in some stainless maillons as these had almost entirely corroded (will include some pictures later). The ropes are very old but don't show much sign of ware for the most part, besides being very very muddy. Having said all of this, I've been up there three or four times in the last year when needed.
I'd suggest that the filthy five should probably be avoided for the time being but it's entirely up to you
I reached out to the DCA earlier this year and they have agreed to add it to the rebolting list but will wait until st valentine's is open (the reason I went up ff in the first place) to do it.
Hope that info helps!

Photos of the maillons originally on the filthy five. Some have been wire brushed to remove rust/corrosion.
Also forgot to add earlier, the in situ ropes currently on the far curtain side of the route to east canal were in a bit of a bad way last time I was there so would well be worth bringing your own

I would be surprised if those maillons weren't pretty close to full strength (or at least close enough that they'd still be 'fine'). Bit of surface rust isn't a disaster; most of the metal is still there after all.

The photo doesn't really do it justice to be fair. In some spots I'd guess that maybe 1/3 to 1/2 of the metal is still there from the original. Also some of the gates (what is the correct term for the spinny bit of the maillon?) have decided they wanted to be able to slide instead of spin so I'd imagine that would decrease strength quite significantly.
Hopefully they're still good for 5kn or so because that would make me feel better

ah yes, under closer examination some of them do look pretty knackeredThe photo doesn't really do it justice to be fair.

I must have just glanced at the ones that are slightly less bad.And if the gate isn't screwing tight then they will be _massively_ weaker than the rating.

Well we can find out exactly how bad they are at some point. The OP is going to fire them my way and I'll film the results from the pull tester and post something here.ah yes, under closer examination some of them do look pretty knackered

Just a quick update on the rusted maillons from the Filthy Five. Ollie posted me 5 of them and I got the tester set up in the office a few days ago to break a bunch of different samples that I'd been sent by various people. I've just sat down at my computer after breaking the last of these maillons and I will be editing together a video of the testing this week. I'm going to keep you all in suspense until the video is ready, but there were some very interesting results! In the mean time, here's a couple of close up pictures I took of the worst offenders.

I don't mind putting new anchors on behalf of DCA (once approved during a committee meeting)...
I wanted to visit FF to inspect the sump from the other side...
After speaking to SamT there's someone else who wishes to sort the sump out? We've got another three people who are also keen to get stuck in and help!

That would be me I guess? I've been doing some work at st valentines for a while, with the help of Sam. I'll update the thread when I get a chance so everyone knows where it stands currently.
I believe I asked Pete (possibly last year) about resin anchoring the filthy five and it was approved by the DCA as you said, but the idea was to access it from the top once st valentine's was sorted out, which has proved more difficult than I thought. If you're happy to go up the FF and anchor it that would certainly be faster...
As far as the maillons go, I just hope they break above 5kN ish to make me feel better haha.

I have created a new thread with the results of the maillon tests in the equipment section of the forum here:

Heavily corroded maillons from the Filthy Five pitches in Giants
Some months back, UKC user 'i think it goes' (Ollie) posted some pictures of some corroded maillons that had been removed from the fixed rigging on the Filthy Five pitches in Giants Hole. The details of that can be seen on the original thread here. Having recently put together a hydraulic rig...

Hi guys... keep me in the loop.
Not sure why the pump isn't working to get the syphon going. My guess will be that its not pushing enough volume of water through to completly fill the pipe (now that its quite a large diameter). Bit like a dodgy toilet cistern syphon where you have to give it 3 or 4 stern pulls on the handle to get enough water over the top to start the syphon going. Or, there's too much resistance/head (though it should be no more than about a metre or 2 max head) and the piston in the pump is not sealing well enough, i.e. water is being forced past the piston in the pump, rather than being forced through the pipe.
Are you sure there are no 'leaks' in the junctions on the other side. If air can get into the system, it wont syphon. I was hoping initially to get the pipe through as one long pipe with no breaks. to ensure its integrity and prove the system works. Then introduce joints to neaten it up a bit. (appreciate the pipe was probably not the easiest to drag down there, but did suggest leaving it uncoiled in a field for a while to straighten it out first).
If anyones heading down in the next month or so, give me a shout.

Would one of these make life easier?
