Been using varistream for 8 years n no issues till recently. Interested to see what everyone else is using.
-
pf digi controllers which are spring controllers just rebadged.
-
d .a componants at the minute running 6 of them in three vans without any worries and a great guy to deal with as well
-
The original crow electro - eco flo ( prior to becoming spring ) mk1 controller - its just an anologue dial and a blue led that gets brighter the more you turn up the flow. Robust, absolutely basic and idiot proof ( which suits me fine :D ).
Tried one of their digital ones and hated it, ended up giving it away. 11 years old now and still going strong.

A £1.50 switch know thing
-
thinking of getting analogue controller this time
-
Currently using PF digital. Took some getting used to the 3 second delay when using a trigger valve. Found it very annoying. Analogue one was instant. However, not such a problem now I'm using the uni-valve.

A £2.50 voltage regulator for a motor and have been for about 6 years.

And if mine packed up thats what I'll be doing too.
I've lost count of the number of "problem with controller" threads - seems the more they do the more goes wrong .
-
Liquid logic analogue from Gardiners.
Id never use digital.
This has a seperate dial to adjust the "dead end" psi which is great. Past digital ones I used were a pain to adjust.
-
streamline digital controller(pumpbox).now ive sorted the dead end out for gas heater its been really reliable and shuts off within 10 seconds even with very hot water.

how does this work? will this not mean pump is full flow at all times?

pure freedom analogue controller ordered.

No. The analogue controller has flow control dial instead of digital control. Other than that it it works similar to the digital one. My old analogue controller was instant in response. I pulled the trigger, I got water. The digi one has a 3 second sensing cycle I believe which means it doesn't always respond instantly. Initially I found this very irritating as I was operating the trigger every few seconds whilst working which meant I had to keep waiting for it.
-
I've never had any issue with digi controllers myself as when I turn the water off at the pole and turn it back on again the flow is instant. Maybe you did not calibrate the controller properly, prime the pump and/or bleed all air out of the system first?

Smurf with my previous varistream it was instant. This current one has a slight delay. Tried adjusting settings with no joy. Analogue this time to see how it goes.
My first varistream i had from 2008 up until a few months ago.

I posted on this problem last June in an effort find a solution to this and the responses were interesting. Here's the link:

It would seem the delay is part of improved detection circuitry in the controllers. Personally I don't like it but have learned to live with it. Have to say I very nearly took the controller off as it drove me nuts.
-
You don't get that issue on digi spring type contollers I use so can't say what varistream are like as never used one.
Going by the other link you posted your using a pf trolley with a spring digi controller the same as mine. I would diduce that you're not bleeding all air out of the system when the containers run dry and/or change them over as is sucking in air so the controller will not work as it should unless you do so.
-
Im not using trolley. Ye must have me mixed up with someone else
-
Sorry I was responding to M&C I think? Who knows as It's been a long day ;D

Hi Smurf. It's me with the trolley. The problem isn't caused by air in the system. I do get that with the trolley from time to time and it just causes weak sputtery flow and is easily fixed by disconnecting the hose at the trolley for few seconds until it reprimes itself and you get a solid flow.
According to Ian Shepherd it's how the controller is designed. And I never had the issue with the analogue version. When shutting off the flow with a long length of mini or microbore connected, say 100 mtr, the pump pressurises the hose and it expands. When turning your tap back on the hose squeezes the water it is holding out first while the controller continues through it's cycle and switches on. So it gives the appearance of switching on immediately when in fact it isn't. That is not a problem for a system that always pushes it's water through long lengths of hose before it gets to the brush. However, I like to work with a short length of PU pole hose which doesn't share the stretchy quality of mini or microbore. So when I shut off my water flow, there's next to no expansion in my hose, so the delay caused by the controller cycle is quite noticeable. However, all that said, I'm now using the univalve coupled with fan jets in my brushes and am finding I'm using a lot less water. So I'm not so concerned with shutting off the water every few seconds now

If you catch the very beginning of that cycle, the 4 second delay can seem like a lifetime. >:(
We even notice it with 100 meters of minibore, more so in the winter when the water in cold and the hose stiffer.
We are still using the Mk1 version of the digital Varistream controller. I have noticed recently that the calibration values aren't the same. A Varistream is preset at the factory to calibration C for a Shurflo 5 liter pump. Its now 'wandered' off to 7 which is way down the scale.

Like I've said before I've never really noticed any delay at all. That is using both 100 m minibore and/or just a short run of wfp hose connected directly to my old pf trolley. That's even using hot or cold it still don't make any difference. I tend to set the water flow quite high so like you say when turned off the pressure builds up depending on de settings how high and when turned back on again. Yes granted the flow is stronger to start with but still there seems no 3-4 second delay when the water starts to flow again or that would do my head in.
Mind you I don't keep turning the water on and off like some crazed posest univalve pole tuggers ;D
-
I still have my analogue controller. The battery in my trolley normally lasts about a year so when that's up I may put the analogue one back on.
-
Personally chaps (and this is just my opinion before i get abuse) i have never really seen the benefits of using an electronic flow controller.
Right from the beginning I have used a tap on the end of my hose and just let the pump pressure switch regulate the hose pressure.
If i want a small amount of water i let the tap out slowly, as the pressure drops the water flows and the pump comes on.
When I shut off the tap the hose pressure builds to 100psi and shuts of. Advantage to this is hose doesn't kink as its under pressure, i have INSTANT water and of i want to blast off some bird muck i can quickly open the tap and get a 100Psi blast (sorry 50psi blast as there are two jets)
Always thought an electronic pump controller was a solution to a problem that never existed...just my opinion.

;D ;D ;D

Controller changed over. Guess what same problem lol. Must be pump that is fecked. Pumps for few seconds then just loses pressure n builds back up again. >:(
-
New pump on now and pumping again. Some issues with dead end on pure freedom analogue controller. According to manual dead end setting should sit between 12-2 o'clock on dial. Mines has to be turned back to 0 to stop flow. ???
Also yet to see red led for pressure switch turn on. This is turning into a headache. Never ever had any issues with pump controller really over the years.
