 could anyone tell me if i can fit a 200ltre tank in my van and fill by gravity alone to the back and refill my trolley that way instead of using gerry cans

 or do i have to fit the pump kit

So long as your 200ltr  tank water level is higher than what you are filling then yes.

aaaarrrr   thats the problem  i probably have to fill small jerry cans then fill trolley but its mainly to store more water any way and to stop running out       thanks

Can't you fill the trolley while it's on the ground outside the back doors of the van OR an upright van tank could make things easier.

no the trolleys higher than the van floor so jerry can 10 ltre  on the ground outside  then just top up i rather have a flat tank so i can store stuff on top of the tank

You can still fill the trolley from the van tank even though the top of the trolley tank is higher than the van floor BUT it will only fill by gravity up to the same level as the water in the van tank.

could you fill your cup from the kettle if the cup was a foot higher

zzzzzzzz

[mikey]

eh

Mikey.
You would be best off using an upright tank if possible. If your tapping from the van tank is at the bottom then the van tank will empty until the water level is the same height as the top of your trolley reservoir /barrel. If you use a 25l barrel then this will be level with your bumper.... no problem. if you use a 35l fixed barrel type trolley which may be higher then just tip the trolley back a bit.
It's not difficult to work out. if you are having a pee then why does it stop when it does?   Easy . Your pee hole is lower than the reservoir. When thats empty the pee stops. Using this analogy anything lower than your tank exit hole will fill up.  Gravity works on everything, beer bellies, trad guys falling off ladders, wfp poles collapsing too quickly.

thanks
     i just didnt want to buy the kit  then then realise i needed a pump

[mark dew]

for the time it takes to gravity fill, a pump would pay for itself very quickly.

[mikey]

yes  mark i understand the time might be consuming thats another one of the issues i think iam just better off  tank plus veristream pakage

thanks
