Are the tanks used in W F P presurised(sorry about the spelling) and could you cut a hole in one and put some sort of screw top in, so it could be refilled. So if like me you need to top it up it could be done, then carry extra water with you.

the tanks are not pressurised, they already have a screw top to fill them, I'm not sure I understand what your asking, you want to carry extra water to top it up? that water would have to be filtered also.
What size tank are you thinking of getting?

 i have a trailer with 200 ltrs and i think if i need to i could take filtered water and top it up.But i don,t have anyway of filling the tank. so can you cut a hole in it without doing anything to the way it works.

[cybersye]

what tank is it ? any pictures? surely it must have a hole in the top already, how do you fill it up?
sorry I'd like to advise you but I'm still a bit puzzled.

The only tank i can think of he's got is a water tank you find in the airing cupboard

Toff. How much water do you use?

Buy a water tank that's for wfp, but get one that's bigger than what you need and is within your weight limit.

Think my 400l tank was about £150, but i'm sure Rich P@F will correct me if i'm wrong

Go buy a small shower pump from a caravan shop for refilling from a small water container to your tank connection.

old style black  ionic tanks where like that on the smaller 300 l   no way of filling through lid may be one them
