I pondered on this for a bit now, spoke with vyair today and he told me the 10 lpm, and not the 12 lpm would be best using 8mm hose or less
Will get it fitted over the weekend and let you guys know what I think of it.

had mine now for about 2 weeks wired straight up the the controller. Works well ....

Hello mate,
I spent the week hating my new pump, set calibration to 30 as says in booklet but controller keeps flashing de ( dead end ) which then cuts the pump out,
Tried speaking to Phil at vyair but he's about as much use as a chocolate fire guard
I have tried cal on every number tried auto cal and have now worked my way back from pump though Di and into hose reel which is were the problem seems to be, entering the 8mm hose.
Any suggestions before I end up putting it in the bin.
Or
Could u by pass this by using a switch instead of the controller supplied or buy another controller
Thanks for any help it appreciated

I don't know what size hose a 12 lpm pump would require but a 10lpm needs 8mm hose. I've used a 10lpm pump on 6mm hose without a controller and it's no good. The pump cuts out due to the pressure. I don't like 8mm hose so have downgraded to 6 mm and now run a 7lpm Vyair pump which is a very good flow rate.
Don't like 8mm hose so the 10lpm pump is just a spare really.
-
You need to adjust the pressure switch on your new pump, calibrate your controller to the recommended setting
then turn the screw on the pressure switch anticlockwise slightly until it stops dead ending.
I think its anticlockwise for your problem but if that doesn't work try it clockwise.

Pressure switch on a Vyair pump?
Yes its like a small cylinder that sits out on the side between the pipe connections ( that's as good as I can describe it)
I think the screw is between the wires but 100% sure on this.

Am on way home now so will check wen i get there
Fingers crossed
Thank you very much for the help

I just wired mine straight into the controller, Varistream mk 1. Phil from Vyair told me not to disconnect the pressure switch on the pump and just re- celebrate the controller which i did and its been working faultlessly since....
100 metres of 8mm minibore
-
It all started great, connected up looks good and bang de on the screen,
Only thing I have in mind, is I have an in line hose connect about 70m into hose, would this effect it at all
-
I can't find nothing on the pump that may be pressure switch to turn
-
All this talk about 6 and 8 mm hoses is a load nonsense. When the water enters a 6mm pole hose(4mm Id) and 2x 1 mm jets, does not make sense to me. Vyair on a B/s trip. I am not impressed with there advice I have had from them in the past.
-
Am not very happy and won't be buying again.
Phil can't even be bothered to email me back and I was going to buy 4 of these, lucky escape I think

I've read so many different variations of what to do with different combinations of pumps (flo jet, shurflo) married up with different controllers............(spring/varistream) that i forget what they recommend.Some are disconnect or bypass your pumps pressure switch others are leave it as is . Safe to say if your new pump is not performing with your controller, then bypass your pump pressure switch and all should be fine. You did say initially it all started up fine and looked good, but went downhill after that ? Thats your problem. Bypass the switch. I also notice the bumf for the vyair pump says 100psi, switch cuts in at 80PSI ?
-
There is no pressure switch adjustment on those pumps. Switch is either on at 80psi or off at 100psi as per label. The best results I have had was when solid tubing was installed all the way to hose reel which resulted in better calibration. I have messed with 7l pump for over 2 years and found that it can be temperamental depending on hoses used due to expansion under different temperatures.
Additionally it uses more juice from battery than flojet or shurflo pumps as de flashes for a while and the pump cycles until switch activates. If pressure switch is bypassed you will need to sizeable battery and bench charge every night. It uses 10 amps constantly and can easily discharge battery below 50% in a single day easily shortening its lifespan.
-
Loads of info guys but I still don't know what or how to do this bypassing, all the equipment works.
I disconnected hose that goes to hose reel with 8mm and the pump kicked in with water flying out so my problem lies as the water goes into the reel ???

Top right hand side of pic you can see two wires going into a switch ? Pull them off and join them up together so they are not "switched" on or off.
-
Looks very similar but am sure the top is different we're the wires go in, am in bed now so will have to get back on it in the morning between jobs were I can,
Thanks mate

Isn't this a shurflow pump your describing?

.
The ten liter pump does not have that layout. The 10 liter has a round plastic cover over the pressure switch which slides out in a upward movement if the pump is standing upright as in the picture.

Thanks slap dash !!
This forum is the way forward !!

No if you look at CleanClears picture the pressure switch has the 2 wires coming from it, that's what I was trying to describe
badly.

Thanks Sean, I'll have a look later. I'm sure when I spoke to Vyair a couple of months back they said there weren't any adjusting screws. I'll have a look and see, on both pumps, the 7 and 10.

Yes I think your right there doesn't seem to be any adjustment on the pressure switch they are set to switch off at 80psi
-
Only just finished this job so am back in the van, I haven't looked on the pump it self but the invoice says and I was charged for a 10 lpm, not stopping til I get home but will look on the pump,
Phil has been in touch from vyair, he's offered to replace but am all for fixing it first.
He's suggested running pump direct from battery without controller which I will do this afternoon and will bypass this pressure switch if possible first.

Pump is 10 lpm says on the tin, took cover off and it's pretty much the same as cleanclear pic.
-
Just gone onto the vyair website and from there pics, you have a pressure switch wired in (the part where the blue connectors go in)
http://www.vyair.com/scripts/prodView.asp?idproduct=107
(Click on the different thumbnails to see the difference in pumps)
You need to disconnect the two blue connectors
Then the two wires at the other side of the pump (barrel side), they go into the controller
-
Ok, so I disconnected the 2 wires that go into pressure switch, with the controller still connected up. This then gave me nothing and when I connected them together it showed P5 was flashinging on controller 😡😤
So I have ran the wires from the pump to the battery which at least has gave me a working pump, well impressed with flo of it just need to speak to vyair tomorrow and sort this controller out
Thanks for all the help guys it's appreciated as always.
