Fresh Water Tank Locking Cap (1 Viewer)

[dellwood33]

Is it just me or do others have problems in unlocking the cap on their freshwater tank ?
One time I can unlock & remove it without any problems and then the next time I have to fiddle about for anything up to 10 minutes to get the cap unlocked & removed.
Are there any remedies or do I just need a new cap

My water cap has always been like that, thought they all were.

Thats why Beer Bottles are made so easy to open:thumb:
Joking aside it seems a very common problem, and a new cap cures it, but it soon returnsoh:
You could try lubricating the key by rubbing a lead pencil over it or using dry graphite grease dont use WD40

They all do that Sir.

Somehow I managed to get some silicon grease into mine and now it's much improved.

I have tried the graphite trick, but it still is a lottery as to whether it wants to unlock or not. Think I will leave it unlocked & see about a new cap (Size XL and with a peak before anyone comments) at Stratford

Yep same as above Silicon Grease is what I used, had no problems since.

Maplins do a small aerosol can of it Link Removed

Hi dellwood I turn the key before turning the lock and that usually worksoh:however my wife always struggles with it and a bit of grease doesn't hurt:thumb:

HI DELLWOOD
this does work and it costs nothing

take cap off and submerge it in boilling water for about 40 seconds.
you can even hear it click into place when you lock it.

I DIDNT TELL YOU TO SUBMERGE YOUR FINGERS JUST THE CAP.POUR THE WATER OUT BEFORE YOU LIFT THE CAP WITH TOWEL TO DRY OFF :thumb:

Doesn't greasing the cap taint the water or do you take along another source for drinking?

I've always wondered what's going on in the world when one has to resort to locking such a device.

Mine has the older type fillers that i have just replaced with original fittings.All plastic.No metal comes into contact with the water and a lever (plastic) that can be locked if really required.

hi we had a OMNISTOR cap which was trouble, it finally would not come off at all, I fitted a new FIAMMA cap and base fitting (very easy just 3 screws a clip on the water pipe a bit off white sealer round the outside for water ingress protection) the fiamma as a proper interlocking cap and is so much easier to use ps I got mine from Pickering show last year about 15 pounds i think.

Shifter - Just tried your boiling water trick & it worked a treat.
You are right - you can here the key clicking, something it never did before.
Cap now locks & unlocks when I want it to & not when it decides it is convenient.

Thanks for the Tip

I sprayed mine with silicon nylon/rubber lubricant from Halfords (or for half the price from French supermarkets).
This overcomes any problems which could arise from using WD40 on plastic materials.

Visions of all these vans.Where do you get all this water?

Don't all these lubricants taint the water or don't you drink it?

good job it was afresh water cap . not a grey water, or even a black water cap , you,d be in the s**t then thats for sure . the kettle or pan wouldnt be too nice afterwards either .i,ll look for a new one for you in holland pappa dont want you feeling the cold.

I had a similar problem on a Euro Mobil van I had and I discovered the the key had very small notch in the top and if it was turned about 2mill too far the notch would catch and prevent the key being removed, once I got the hang of the key being in the right position I had no further trouble and was able to lock it easily, as my van was new at the time I was supplied a new cap after complaining , but never needed to use the new cap as I got the hang of the old one as explained and was too embarresed to own up that there was nothing wrong with the original.:Blush::Blush:

fresh water cap

A couple of months ago my boy saw me struggling with the water cap and - not knowing the boiling water wheeze - took it apart quite easily and found the lock-pin locating spring had miss-aligned.

Job Done.
