Am going to put 2  350 litre tanks in van.  Ma problem is   How do you connect the 2.  I.e. When the first one empties you don't have to disconnect pump etc     How do I get it to  suck out the second tank when say the first one is half empty   

[nathankaye]

Why are you doing it this way anyway? Because you happen to have tanks or are you keeping then seperate due to chemical  use?

If first option, sell them and invest in one tank!
Alternatively, are you stacking them on each other (with support) or side by side (infront of the other)?  Simply feed tank a into main tank b. So as water level drops, its automatically starts to fill. But maybe incorporate a tap so you have control (for whatever reasons your doing this)
Whats your plumbing skills like?

I take it the two tanks are going to be used for just water and not chems?

First put taps/stop valves on each tank outlet so each tank can be turned off independently. Then connect the outlet pipe/hose from each tank with a joiner so you end up with one pipe/hose to the inlet of the pump.  Best to put a stop valve on that pump inlet too so if need be can turn the water off say if you need to remove/service the pump. What type of fittings you need will depend if you are going to use just 1/2 in hose or plastic pipe.

Myself I use two tanks and just drop the inlet hose into the lid of whatever tank I want to use as I'm still using a pf trolley static in the van. That way I can still use the pf trolley if/when required so have the best of both.

Regards to using chems for now I'm testing a small 55 litre quid bike crop spray setup (8 lpm chem pump) static in the van. I will probably be modding the inlet hose from the side outlet of that tank to the chem pump with stop valves and a joiner with another drop suction hose simular to the pf trolley. That way l have the option to draw from either that 55 litre tank or 20 litre containers etc with the same chem pump when wanting to use different chems. Not only that by adding the stop valves and drop hose will be easy to flush the pump, hoses etc through with water when there is chems still left in the tank.

we have two 650s joined to togather via a simple t joint ,(  we don't bother with taps as they never get used )  from that single pipe get lead  from the front of the van  to a different  t joint where it the turns it back in too to pipes for two pumps

we did it this way because we want both tanks to empty at the same time so the water didn't go off , and it works very well , if theres only one man going out we will just fill one 650 and with in an hour the pressure of the water as pushed the water in to the emity tank so they are both level (i.e. 325 in each )

cheers for reply..... will try one of the above.... like the sound of smurfys

330 swb transits were running at the minute biggest pay load you can get with going to a 350 lwb

I always use taps on outlets of tanks now as had a 450 which was full at the time empty into the back of the van when the gardiner nylon outlet snap off.  Was a finger in the d**e moment I can tell you

Biggest payload for any transit 330 is 1,588Kg.  SWB 2.4TDi (115ps) 330 Low Roof RWD

With 1,300Kg of water, you have 288Kg for fuel, water tanks, tank mounting, driver, driver's mate, equipment.  Good luck on the weighbridge.

That's a mental amount of water to carry about when both tanks are full in that type van surely Susan

we don't care simple as that ,  we have work to do and it get done , we ran for years and year over weight like most vans do that are running out of dhl , dpd ect ect  its like when I am out on my r1 do I think oh should I not do 140mph along this road because  "good luck with the speed gun ?? "

you have no idea on what weight is like on a van , we ran 14 vans in at dhl and city link back in the day , mostly exlwb sprinters, and jumbos which would only carry around 1 ton or so most days they went out with over 2 tonne in weight added to them ,

 I can remember being fully loaded and the last pallet they put on the rear end was 900kgs by itself ! the good old day of losting your mud flaps at the first bump in the road ,

I'd be more worried about how dangerous it is especially with a load like water....to the driver and to other road users.

Some folk are utterly selfish and self centred, mate.

They don't consider stuff like that.

yup  and I am one of them , you should see the looks you get when dropping two gears  at 70 and power wheeling away from  crapy slow cars on the m25

It's rare I agree with you, but you've nailed it here.
