emergency! advice on van mount not working!
« on: January 27, 2009, 01:42:45 am »
please  please read this over and give me some advice,i know its a bit wordy but i figure its best if i put all the info out there for ppl in the know to see possible places ive gone wrong.  :-\
 I did it at the weekend as the old gammy backpacks are done and I really wanted to get it working for the start of a new week. i already lost today and worried i wont get much done for the rest of the week. been up all night pouring over the forum and googling any piece of advice i can find/think of.  :o

SO! I have just put together a van mount system that consists of a 650litre tank, going straight into a 100psi shurflo pump (with a filter) which is controlled by a ecoflo(?) varistream type controller that goes from 1-99 (bought from pure freedom). From there it goes into my di filter and out to (well, what i hoped would be) a y-splitter hoselock connector which then went into two 100metre yellow microbore hosereels, and the two 24ft poles fit in with schrader(spelling?) valves. The controller is wired straight into the van battery (transit swb), and via a fused switch. ???
 NOW! can anyone tell me where i am going wrong, cause when i try to use just 1 pole its.... meh, not good. works good sometimes, millions of pressure then crap, then its good. Ive been over every joint to exterminate loss of pressure thru leaks etc all is tight as a drum. Theres not a chance of there being enough pressure to run two poles off it, when i try it barely trickles out of the second pole. I have read many times 1 100psi will be able to run two poles but am i expecting too much of it?  :'(

suggestions, comments, request for pics of it, anything that could help would be appreciated.

thanks in advance!

sounds like the pressure setting on your eco flow isn't set high enough - I don't have one so don't know how to set it.  either that or its the pressure switch that is cutting out.

I've never been to bed with an ugly bird but I've woken up with loads!

oh by the way 100psi is only the pressure switch setting, it has nothing to do with flow and therefore has no bearing on whether you can run two or more poles from one pump - flow rate is much more imortant, you need a high flow rate for two poles.

Am sorry i haven't got an answer, just an alternative but you could try running your setup with the ecoflow disconnected.
I just have the pump with no flow controller. I Have an on/off valve between the water tank and the pump to regulate the flow.
I personally prefer this setup to using a flow controller. (I also used to have a freeedom trolley plugged into the tank).

Take off the outlet hose off your pump and then try it .If it pumps ok without the the hose on then its your pump.If it still doesn't work then bypass the flow control and then try.I had the same problem with my pump not working under the pressure of a 2ft piece of hose.Took the hose off the pump and it worked.

also do you have a vent in the tank ? if you dont unscrew the lid a little and see if that cures it, if you cant get the lid off it is locking air

Have you set the calibration on the pump?

To start with check the 'dead-end' setting on the Eco-Flow. It may be turned right up so is too sensitive.

Next disconnect the eco-flow and just use the pump, does this cure it?

Doesnt turning it up make it less sensitive?

hummm. this is quite weird as this was happening in one of my vans yesterday. I have just replaced a flo jet with a sureflo and digi varistream. it sometimes just starts to splutter and loss of pressure for no reason so if anyone has any ideas on this also i would be interested to know. Thanks

When that happens Steve its the calibration of the dead end setting.

Press both up and down arrow at the same time, the display will show 'CAL' you can then adjust the pumps sensitivity with the two arrows, up or down, when youve altered it press the < arrow, next to the two up and down arrows to save the new setting.

I meant maybe  it was turned in the wrong direction, as you say up is actually less sensitive. So it might be turned right down I should have said.

just tried it but when he is holding down both arrows the setting just goes up to maximum...no 9! any ideas?

Aaaa, no sorry, my fault, you have the varistream, I was talking about the digi-flowmaster. Sorry mate.

Did you get it from PureFreedom?

no i didn't. i can't even think where i got it from. how good is that? ;D so does this not have the same thing for sensitive setting?

wow!  :o 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!  ???

is the pump running, and your not getting any pressure out hose??

Steve

You mention 'microbore'.

I use 80 metres of 5mm internal diameter clear pole hose. That is microbore (6mm is also microbore). My flowrate into a bucket, from one brush-head is 2.5 litres per minute without any other restriction than the size of the hose.

I have been given to understand that it is more usual to use 'minibore' hose where the pump needs to move a lot of water.

Minibore has an internal diameter of 8 mm, which puts much less 'drag' (friction) on the water so that the flow rate should be much better.

If you are using 'microbore', this could be one of the factors involved.
