Seems a few people do without them and use a bypass system. So i have been looking it up on here but i havn`t quite grasped it.


As i understand it the pump runs continually and when the pole flow is shut off the water diverts back to tank and this is done with a loop before and after the pump. Its the flow control valve in the loop i dont quite get,is it just a tap turned manually and does adjusting this mean the flow rate to the brush is controlled ?

I reckon my pump would be taking less abuse if it ran continually on a job instead of stop/starting  intermittently when using a trigger/pole valve/aqua whatever.

 At the moment i am thinking this type of set up seems more reliable than electronic controllers and far cheaper,any thoughts/facts/advice/diagram/pic   greatly appreciated.

Sean, yes you have grasped it correctly ( well thats how i see it )  the tap is used to slow or speed up the
bypass this allows more or less water through to the brush.

if you change over you will need a pressure switch (soleniod) on your pump - as ones with variflows dont
always have them

Cheers for the reply,i have a spare pump with pressure switch and as long as i understand the bypass system then i am not stuck if i get vari-problems,that will then give me piece of mind plus if i have to go to a bigger tank then i have to set up the system myself as the Brodex kit i have now is all built in and not really transferable. I`m off to remind myself and have a laugh at HOW MUCH Brodex want for a 500litre system.

Bear in mind that your pump will be running at full throttle all the time- draining battery more AND the flow will reduce as your pole goes higher.

I've run both systems & I would NEVER go back to a bypass, Digital varistream all day long! Never let me down in three years & performs perfect day in day out & because it uses only the minimum power required I can run direct from 12v cig' lighter socket ALL day.

WinPro -  enlighten me on why with bypass the flow rate reduces with height as opposed to with a flow
controller ?

Resistance smudger, more pressure needed to push water higher & it takes the path of least resistance- back to tank. A digital varistream monitors this & auto compensates meaning a constant flow rate regardless of resistance.

[Smudger]

thank you !   

i thought that to be the case but wanted my suspicions confirmed

You're welcome darling.

I personally don't think that the bypass is a great idea as the pump goes flat out even when your not cleaning windows. An electronic flow controller that is set up right (stops pump shortly after flow stops) should work far better in my opinion.

However if you wanted to save money by not having an electronic flow controller then a better way would be to use a pump with a pressure switch and have a valve fitted on the negative side of the pump where there is no pressure.

I run one pump for 2 hose reels with a bypass back to tank. Been going for over a year no fuss ... brilliant, without electronic controller its just one less thing to go wrong.

If i did it again instead of back to tank, id T before and after pump and put an inline tap on the loop.

So simple and very effective...and reliable...oh and cheaper lol

thats exactly what I do without problems

[Nameless Drudge]

So t before and after pump has the water circulating in a loop if not going up the pole and the inline tap on the loop would just be the lever ball type?

[♠Winp®oClean♠]

I don't see the cost of a controller as an issue whatsoever, it's only what, £90 or something!

I also don't see anything to go wrong? set up right in conjunction with the right accompanying equipment & it does all the work for you!

You'll get the cost back in pressure switches & batteries let alone wearing the pump out faster.

I used to use a bypass then re-circulating ( T pieces ) & always thought it was great, what else could I want? I actually got a digital varistream kind of by accident, I didn't want it after reading about people having problems with them on here.

However, am I glad that I did! Superb piece of kit & wouldn't be without it now.

You can run a pump without a controller and without bypass back to the tank. Just so long as it has a pressure switch fitted such as the Flojets on Gardiners website.


If you have a tap on your pole when you turn it off the pressure switch on the pump turns that off.

You can indeed Matt BUT it runs at full all the time & IMO the pumps own pressure switch isn't a patch on the electronic one.

Hi Winp, I notice that you have a digi varistream. Do you know how the settings work on the control buttons? Ive tried holding - and + buttons down and turning on/off etc but still seems to be running too fast.
Cheers in advance

I got a new controller and pump from Alex recently. The controller was duff, one of the circuits had gone inside I think. So for a couple of days I ran the pump with no controller and to be honest I thought the pump at that time was running at about the equivalent setting to what it would have if the controller was on 60. I reckon those controllers slow them down to be honest and when you run them at say 65 or above the pumps are actually being pushed higher than their default speed.

must admit I never use my bypass I turn it up full and rely on the pressure switch to turn off. I have no need for low flow rate.

Now that is interesting,couple that with the apparent truth that a pump draws nearly twice as much current when starting up so when cycling on/off when theres no flow then the bypass starts looking very sensible.

I can't speak for Gardiners units matt.

But yes, that's the idea, to slow it down. I can count the revolutions when my pump is on my desired setting.
