If anyone can help with this please folks...
I have a 650l upright tank from pure freedom in the van and I fill it almost to the brim daily as I'm doing my 1st cleans on wfp an using a lot, the prob I'm having is the lid is leaking at the pressure cap/valve as the water is too high in the tank, the pressure cap seems to let air both in and out hence water leaking out through the top. I would have thought the cap should only be air in to prevent this? What do you guys use (is there another cap or do I just mastic the cap and then open the lid when the tank needs air?

Cheers
Fin

Those Wydale tanks are crap,when I got my Pure Freedom system installed a few years back I've learned to fill the tank to just above the baffles,otherwise  the slossing about results in water coming out where the lid is,the lid itself has a rubber seal but it's just as usefull as having an unberella with no material in a heavy down pour.

Take the air vent out and silicone a 6" piece of hose pipe in the hole.

OR PUT A CARRIER BAG ON THE THREAD AND THEN SCREW LID ON

OR THE BELOW IS GOOD.

Cheers chaps, if i do the carrier bag will the water still work ok without drawing air, or will I need to frequently undo the lid?

once primed the air should only be a driving force downwards.
air in the system is a leak.

Drink bottle top with pin prick. Worked for me when I had a wydale tank.

this works very well - either remember to remove bag after 2 or 3 jobs or you will get a vacuum - i put several small holes
in it with a knitting needle this allowed air in/out but stopped the water coming through the vent in the lid

First solution.........only fill to a certain point so as no water leaks, this is what i do,375 lt mark on a 400 lt tank and or take the lid of run some silicone sealant around the area were the rubber seal sits re install lid at the end of the day unscrew, it may be tight and this will create a seal which may last up to 2 weeks

Firstly you need to completely seal the lid.  This includes the 'breather' which allows air in.  You can buy spare rubber seals for under the lip of the lid, fit two together with some silicone between them.  Now you need to allow for air to enter to replace the water taken out, but a small hole is adequate.  We drill a 1/4" hole in the lid and insert about 18" of 1/4" John Guest pipe (standard on most RO's) it makes a tight fit in the lid.  This allows air in but water won't splash out of such a small diameter pipe over the 18" length.

Tape over the vent with.gaffer tape or similar then put a few holes.in. With knife takes 2 mins , works great , mike

Cheers Ian I'm going to do that, any idea where you can buy the seals, or I suppose I could just mastic it.

some good ideas here, im currentyl doing the plascic carrier bag one 

what i have been doing since day one however is just tightening the lid and tight as i can (by hand) and wrapping a towel around the edge of the lid, so as to obsorb the water that leaks. you nee to wring-out the towel now and then but its worked well enough for me not to worry about finding another solutions.

but i must admit i tried the plastic bag trick today and its worked like a charm!  no more towel and no more leak. im amazed!

thanks

^ did the bag today too GB. Worked fine but I was concerned so I rand Wydale, they said the bag is ok, but water pressure to hose may be reduced (although mine wasn't all day). They advised to drill hole in the top with hose tail as air should be replaced in tank when water level goes down.

my lid has a primer/air escape valve thing on, so i stabbed a big hole in the plastic bag! and like you said, didnt have reduction in presure out the jets all day either! thanks
