My first day working with new Gardiners 6mm inner microbore, lovely hose very light and easy to work with, but the problem I am having is with water flow.
I work with a high flow but I'm not able to get it with this hose, with my old 8mm hose I had my controller on 80 and had a great flow but with this 6mm i've turned it up to 99 and it's still not as high as I would like.
Is there anything I can do about this, I was wondering if you do bigger pencil jets or anything that may get my flow up a bit at the brush.

You could - as an experiment - remove the flow controller, re-wire the pressure switch back up, add a £2 on/off switch from Wilkinsons and work that way.
The bonus is that you haven't got a flow controller (keeping it simple) and you might have the flow you like to work with.
We do this, using microbore, and the flow we get is spot on.

I don`t know if I am just dumb but a 100psi at 5 liters per min through a 6 mm hose or a 8 mm hose will come to the same thing as if will jut move faster in the thinner hose and slower a thicker 8mm hoes.I cannot see that 2 mm ID would have such a big different.These are some many things having an impact on the difference e.g. the fittings ID, The pole hose id, THE JETS. ETC. My advice with all these flow is just chuck you digital controller and make yourself a analog flow controller or better just a switch. The controller are not worth the money they cost.( Sorry Ian Shepperd)
Save water= SAVE MONEY TO SPEND ON CONTROLLERS ITS A NONE BRAIN-ER.
-
Yes I think you're right chaps, I think it's time to get rid of the controller and hopefully that will put me back on full flow that I require.

I've just started using the exact same hose- 100m of Gardiners 6mm. I've used 8mm for about 8 years & all I've had to do is increase the pressure cut off by ONE value (MKI digital varistream). The flow remains exactly the same as with 8mm hose on the same flow setting too.
I would check other things first, air locks, strainer etc. ;)

I'm assuming you realise you'll have to increase the pressure setting (calibration as some refer to it) to compensate for more resistance from the smaller bore?

What is the usual flow rate that you work with? Have you ever measured it at the brush head? What is the current flow rate you are getting with the 6mm ID hose?
Which pump and controller are you using?
Most users find that 100m of 6mm hose provides plenty of flow rate. So unless you are used to a very high flow rate it may be something else amiss.

I would tend to agree with this. Changing the ID of your hose will impact on the system pressure as will the different expansion rate of the new hose.
A smaller bore hose can increase the hose wall resistance and back pressure created in the system. I would suggest recalibrating the control to the new set up.
The pump is working as hard as it did before however the change in resistance will make flow appear reduced.
Pressure Dynamics link: http://www.springltd.co/node/138
The system will lose pressure between the pump and brush head + no pump is 100% efficient if you start with 5 LPM at the pump by the time the water is restricted by Hose wall, Jets, tap and length of hose you will have perhaps 3 to 3.5 LPM at the brush. Setting the control on 99 means the pump is probably running around 90 - 95% of capacity.
The controller is not just there to regulate pump speed, It also helps mange the battery and provide other information.

I don't use flow controllers and found that when I used the 6mm ThermoboreBore it came out alot slower so bought the 8mm red ThermoboreBore which was nice and fast but for some reason the heat kept knocking out my pencil jets as I use omnipoles hexagon jets which make the water flow faster, so stuck that thermo in the shed now gone back to the yellow 8mm hose which I don't go to hot anyway and the jets stay in the brush !!!! 👍😏👍

The 8mm has a lower hose wall resistance. In affect the larger ID hose means there is more space for the water to flow. I had an interesting discussion this week with a Dutch distributor who sell 10mm ID hose.

could be you've got a kink in the hose in the centre of your reel.

Alex, why can't I buy a pole from your depot, willing to pay cost of courier to N Ireland, only being told that I can only buy from one window cleaning shop here in the north,, cheers,,,

Where possible we always encourage clients to purchase direct from the Distributor in their country. One of the main reasons that we do this is to simplify the warranty and customer service support for our products.
If for some reason you are unable to buy a product from http://www.surecleansystems.com/?product_cat=gardiner-poles-brushes please let us know and we can look into a solution for you.

Most of the prices are virtually the same as ours. Any difference would be made up for in the cheaper shipping than having to have them sent across from mainland UK.
If you think that there is a serious pricing anomaly please let me know by email.

Don't think I've seen any price difference with sure clean. Only thing is when gardiner have a sale or new products, it can be quite frustrating with the shipping fees

same price, but Gardiner throws in dual trim brush an resi neck totalling 31 quid ,, bit of a difference,

RTFQ - You might want to check it again, the first drop down box says choose inclusive resi neck and brush
