Have a purefreedom 650 tank, and the problem I have is when the tank is full . . . . . there is a lot of water splashing up  with the movement of the van when driving, and soaking the van !    I realise there needs to be a vent in the tank, but is there a way to modify the lid so there is not a swimming pool in the van ?

Silicon the vent up, drill a hole into the lid, fix a hose lock male fitting to it, get a pice of garden hose with hose lock fitting on and cable tie it to roof of van, sorted

Thanks for the tip, the middle bit of the lid is removable, so might fix something to it . . . . paid a lot for the system so a bit miffed I have to modify the lid. . . . rolly eyes !

I used rolls and rolls of ptfe tape and screwed the lid back on. Still get a little come out when tank is full to the brim,but nowhere near as much as before!

place a carrier bag over hole with just a couple of small holes in it for the air then screw the lid over the top. problem sorted

We have 3 Wyedale tanks with the vent in the middle and none of them leak, even when the tanks are brimmed. I would suggest the seal around the lid is the issue.
