Does 8mm have more flow than 6mm
« on: December 11, 2019, 04:37:55 pm »
I know, it seems obvious it should have but I've never tried.

So I got a new reel and fitted 100m 6mm microbore.

The flow is rubbish compared to what I've been used to using.

Compared to my old reel the flow is poor. Then I realise on my old reel I only had about 60m of 6mm not 100m.

So I stuck my old 60m of hose on the new reel and hey presto the flow is back where I like it.

I just wondered if anyone had compared 6mm to 8mm and if I bought 100m of 8mm would I get a better flow?

If not ill just use it as 60m and keep the 40m spare in the van if I ever need it
 although I seemed to manage on all  my work without the extra length.

the longer the length of hose the more friction with the water so the pump needs turning up - but ultimately you are governed by the size of your jets in the brush head - you can only force a certain amount of water through them

Yes 8 mm will give better flow than 6mm for the same length of hose .

6mm is pole hose? For those that use 100 metre of 6mm, is it strong enough to pull hard around corners, through bushes etc without snapping.

I’m thinking of moving over from my trusted 10 year old 8mm hose.

We have 1 reel of 6mm on the van and 1 of 8mm. I notice a big difference in flow rate with colder water.

Microbore is just about 1/2 the size of minibore.

 Not sure if you mean 100 meters of pole hose or microbore ? We use 100 m microbore and drag it around 3 sides of a house no problem much easier than 8mm

Yes, that’s why I only use 8mm Adam, far better flow, I run full wack and want as much flow as possible.

Once you’ve got an electric hose reel, there isn’t much of a reason to not have 8mm. 6mm is great when manually reeling in, but with a leccy hose reel, 8mm is a doddle.

OK thanks

I'm a full whack man myself and with 100m 6mm microbore it felt like a drizzle.

Are you aware that Grippa only recommend 6mm for hot !
Might be too much water to stay hot in the journey to brush
I'm so lazy I'm getting tired of it !

So pole hose is 6mm (microbore)?

And minibore is 8mm?

Noob questions I know but I’ve never had to change my hose or reel in over 10 years.

You can have
6 mm pole hose connected inside your pole
6mm microbore yellow hose goes on your hose reel
8 mm minibore  yellow hose goes on your hose reel

Still worth a go mate 👍🏼 I’m sure it’ll be ok when hose reel is only 20-30m out...

I run 3mm pencil jets as well mate, that helps as well.

Zesty , we may have to investigate if we are compatible  :-*
Big hose and big jets have not been tested yet , mind you if you do come down for a fit we can test  before you buy !

hot water,standard 2mm jets and 6mm microbore and my flow is fine on a controller setting of 45 in this cold weather.....

your just making your job harder using minibore hose....its a real drag(pun intended!)to drag around when using 100m......

adam just turn your flow up or get some sort of hot water system...you ll regret getting minibore hose for sure if your used to microbore.....
price higher/work harder!
