wow!

talk about quick replies! thanks to all that posted.
Ive tried both calibrating the varistream and also just by-passing it totally, it improves some but not that much. In the tank lid ive drilled a hole with a hole saw the size of a hoselock and screwed a hoselock onto it allow air to flow in as water leaves, as well as to fill it up so its not vacum or pressure that way.
i use a normal hosepipe going from the tank to the pump, and then from the pump to the di, should i change the length going from the di to the hosereel to the microbore to see if that gives me more pressure? like its pushing it thru a smaller hose?
i know the 100 psi doesnt relate to the flowrate, its a 5litre p. min flowrate but i see ppl sayin they run with 2.5 2 or even 1.75 lpm and say theyre happy, not a problem so surely i can squeeze two pole from it? two poles of a 5lpm flow rate 2.5 each? maybe not?
The thing is,i know 5 different ppl who have set up a diy kit, nice and simple battery to pump and tank via hose to pump and they all tell me they get great pressure. ive even used two of them, one with a 60ft carbon fibre pole and the presure at the top was insane even still all that way up.
When i connect the di to a y piece splitter the flow is so bad it basically just falls down whichever side of the slpitter is easiest, theres nothing coming out the other side of the splitter. Theres just no pressure! argh!

im going to get a bucket and let the flow come out before the di and then out the end of the hosereel to see what my actual lpm is working out at. But even if its onle 2.5 lpm, surely thats enough?
thanks again for all suggestions, it really helps, even if its just to narrow down possbilities and reassure myself i havent missed something completely stupid!
