Just arrived this afternoon my latest order from Gardiner.

I have bought 3 poles, But noticed they have 2mm water jets in the brush head.
On the Y adapter above the brush it reduces the pole hose from 6mm ID to 4mm ID.

How will this affect flow rate with microbore hose?

Will I get a more powerfull jet of water for Rinseing then if they were 3mm ID jets?

Does anyone else use 2mm water jets? and do you recommend them?

Many thanks if you reply.  Nel.

I'm no WFP expert having been at it for just a few months.

But I use both a Peter Fogwill Salmon Brush, that has two fan jets and an Ionic Residential Brush that has two pencil jets.

Both seem similar to me in that the aim of the jets is to be able to push water out of the brush to give them window a scrub; then to rinse.

I really don't think one is better than the other.  Smaller holes may increase the jet's speed, but we're not 'power washing' the windows.

As Jeff Brimble said in an earlier post, as long as the jets travel past the brush head, he said that was okay.

I also like a fairly good flow rate, around 1 to 2 litres per minute, as it seems I can work faster.

Do any of the more experienced guys think jet size or type makes a noticible difference?

tosh sorry to trouble you but this might be a dumb question but how do you measure your flow rate thanks darren

Darren,

Get an empty bucket, your WFP set up, a watch and a measuring jug.

Turn on your WFP at the normal flow you use it, point it in your bucket and look at your watch. 

After one minute take the brush away from the bucket.

Measure the water in the bucket by pouring it into the measuring jug.

see how long it takes you to fill a container

ie  3 mins to fill a 5 litre bucket

I have 2 Vikan brushes one has 3mm jets the other has 2mm jets. I much prefer the 2mm jets. The water comes out much faster but overall uses less.
I am coverting the 3 mm jets to 2mm ones. You can hear the water hitting the glass.
I think that small and powerful is better than big with low power. That's how pressure washers work isn't it. DAi

With my brodex jets i can squirt about 20` away with my 100psi pump.  I think this is a bit to powerful.

I think i will drill them out soon.with this type of jet you should not lift to rinse as you get to much splash back up to 6 ins above the brush head.

Cheers Dai,

I will be pleased if they increase the power of the water coming through as the rinse I get with the bigger jets is a bit limp to say the least when I use it with my microbore hose.

The 1/2" was fine with the bigger jets, but after 4 weeks of wfp, the 1/2"is comming of the reel and 60 mtr microbore is joining its bigger brother (100mtr microbore)

Nel ps. it seams a contradiction to have a stronger jet but use less water.

Have you got a varistream

[leegooner]

Ive just started using a new vikin brush from wintecs
with brass jets not sure size 2 or 3 m normally us (omnipole0
rinses off much better on new glass but run out of water a lot
quicker

Dave.  NO.

Been working on the van today due to the garage door cable snapping, So had to stay home while waiting for some wire to be deliverd so I could fix it. So I Transfered all pole fittings to m/bore and fitted pole control valves to the M/bore. Taken my 1/2" hose off the reel and put my 60mtr m/bore on. Alltered all the fittings on my Backpack,so I am now useing the handlever that came with the backpack.

Racked up my new poles so they can travell in safety. So I have been running a couple of tests.

Flow rate of 60mtr M/bore, 2 ltrs out of hose (not pole) came in 52 sec.
Flow rate of 100mtr M/bore 1.6 ltrs in a min.

So I may take 20mtrs off the 100 and stick it on the 60 so I have 2x 80mtr. Which should give me a flow rate of 2ltrs a min.

The smaller jets work fine, the water has a little bit more pressure then the others but not a lot of difference.

I am looking forward to tommorw, no more frustrating 1/2" hose, Great.

Nel.
