What flow rate do you use? I use 45.

[Jonny 87]

Asp,depends what pump you have.

I have a shureflow 100psi 5 lpm.

I have my controller set at 90. Which works out at about 2.2 litres per minute at the brush head. Good flow is the way forward.

More like 4.5 litres per minute I would have thought.

You would be doing well to get 4.5 litres per minute from a shurflo pump even flat out.

so you think the shuflo pumps are pants too? sean

Nothing wrong with the pumps Chanster but by the time the water is pumped through the hose and brush jets
the flow will be reduced by a great deal.
I use the higher flow model I think its 7lts per minute and it gets about 4 litres per minute flat out.

I quite often check my true flow rate by filling up a bottle and timing it at the brush head.

The pump produces 5lpm straight from the outlet, not when you are restricting the flow by pushing it through microbore hose an 2mill jets at the brush head.

I use sureflow 150 psi on 50 by myself might well buy one those avyair pumps to see difference

As long as i don't run out water be interesting to see

I much prefer the 150 psi to the 100 especially on fan jets

I have it about 66. Until I used that additive were all on about   now its 99.
High flow rate is a YES for rinsing. Problem is doing the frame. Don't want to use all my water on cleaning frame and glass scrubbing.
Need something that can be set at half the flow rate, then full for rinsing glass. Now that I would pay top £ for

[NWH]

68-80 depending on what I'm cleaning but windows at least 68

[Mike #1]

40 is the highest flow I run at and get a full days work from 400 litres

[Ian Sheppard]

In honesty there is right or wrong flow rate. Each job may require higher or lower flow. Also each system is set up slightly differently to suit the person using it. As a general rule of thumb Flow between 30 - 65 should be ample for most circumstances. Although on occasion flow of 99 for rinsing may be useful.

In some cases simply running the pump faster to push more water in to the hose line can reduce the flow at the brush because of reverse water pressure created by the restriction of the hose.
these two articles touch on this http://www.springltd.co/node/138 & http://www.springltd.co/node/137

The 1st looks at pressure dynamics and the second flow.
One purpose of a controller is to give flexibility of flow rates as needed, while allowing you to use the minimum amount of water, battery power, required for that particular job. At the same time the controller reduces strain on the pump motor, and line connectors as we can reduce pressure in the system without impacting on the flow.

Duncan if you are looking for the ability to get a rinse boost have a look at the Wash - Rinse Ultimate RF controller

Or of course you have the flexi flow version of the ultimate

What's a flow rate?

Just try pinching the pole hose a little if that's what you want to do.
But on a maintenance clean you shouldn't have to spend a lot of time and water on the frames anyhow.

60 with fan jets

I've got exactly what your after.
It's called a tap

[Susan Dean (1stclean)]

we only have one switch now to turn pumps on or off as we all run with water on full but way always have lots of water on board so we don't care how much we use

[johnny bravo]

which is an adaquete flow rate on an analogue controller  1-10

[kempy]

Jonny a flow rate of 90. Wow .
About 60 me .
