Fast fill v Submersible Pump

[dyson123]

Hi, for those of you fill a backpacks from your van tank. Is fastfill/gravity fast enough or is a submersible pump so much faster? Aside from the Gardiner backpack I have a 70l trolley that I could be using on occasion so wouldn’t want to be standing forever filing it….

Subversive pump everytime. A decent pump and 1 inch reinforced pipe is what I use to fill my 450 tank. Fills in from empty in around 3 minutes. Gravity fed would probably take an age and the holding tank would have to be off the ground to get it to be at its most efficient.

Cheers, in your situation it’s a no brainer.
I’m only filling 70l but usually just 20l and the van tank would be well above the level of the backpack which would be on the ground…

Sorry I read it wrong thought it was a external storage tank...

Gardiners do a small submersible pump that fits through the hole in your van tank.
I’ve got one for filling up the odd barrel if I or my son uses the trolley.
It’s miles faster than gravity ???‍?

yeah those gardiner pumps are really good

I have a fast fill on my tank... Its great when the tank is full, but when it's down to half it really slows down.

I think a sub pump is the way to go ?

From what I have seen these 12v Bilge Pumps are nice and cheap at about £18 and do something around 1100GPH so about 70 litres a min!! They only come with 1m of cable though.

Exactly what I wanted to hear in terms of the flow rate coming from an empty ish tank ?

That wasn't the question though was it

Ive just put a bilge pump in mine £12, way faster than filling from the tap.

Does anybody actually have the pump fitted or do you just drop it in the tank when needed

Just leave it permanently in the tank.

Can someone check PJJ is ok. That question was posted 42 minutes ago and he hasn’t responded ???‍?

Thanks for the reply
Leave it through a drilled hole or just through the lid in the tank

I wouldn’t know the answer as we don’t fill back packs or trollies so that’s why I didn’t comment ???

some have a submers then on the hose have a petrol pump type handle to fill whatever needs filling . plug in or connected to leisure battery

I just drilled a hole close to the lid of the tank. I have no ‘handle’ at the end of mine. I just turn the switch off then put my thumb over the end, then lift the end of the hose higher than the tank to release the excess water back into the tank.
If I remember I’ll take a couple of pictures ?

Thanks again for the reply, might have to try that as I keep forgetting to put the tank lid back on .................

the inner of my tank lid dissapeared a few years ago. a nicrofiber cloth bunged in the small hole does the job . easier to fill tank up just pull cloth out and replace
