My Varistream digital has burnt out so was just wondering if this is still the best set up or not. I did try an alternative one a couple of years ago which was not good at all.
Just asking before i go and order a new one, i seem to recall that a few of you dont use these pressure flow regulators at all! But i cant find any threads on it. When i first started 6 years ago wfp i used the built in pressure switch then turned to an analogue varistream.
i run two varistream to two shurflo 100psi pumps individually and onto microbore!
Thanks Craig
-
Anybody???? ???
-
I think you should. As it happens I have one that's only one week old or another that is two years old.
-
I use one, i cant see how its good sense not to. Can control flow/pressure, rather than relying on the pump which is preset.
Id get another in a flash.
-
Mark, if you got 2 up for grabs, sorry mate why are you selling? If im reading that right!
But yeah, i was just wondering whether people were going about things different as i havent been on the forum for quite some time (family stuff)!
Cheers and if you are selling Mark send me an email to craig_riverside@yahoo.co.uk
-
Bought one and thought it was faulty, bought another about two days later and it was the same proving the problem lay elsewhere! Bought two Varistreams I didn't need!

thanks Mark, whereabout are you? im in Stevenage, Herts. How much for each? Postage also if you are too far?
-
sorry, been watching telly. The older one probably £30 nothing wrong with it but would need wiring to the blocks inside because I kept the wiring on the van. The new one I used for ten minutes so probably looking for £60 inc postage. I'm in Wilts.
I'll keep the other new one on the van.

Hi Mark,
I would be interested in buying one off of you.. Can you email me on andy@iconicwindowcleaning.co.uk ?
Thanks,
Andy ;)

If you are used to a flow controller then yes you should replace the burned out controller. There are better units than Varistream but then I am Biased ;D
Check the WFP suppliers who offer a very good alternative to the VS

Sorry Mark had a few probs with internet/computer! If you still got them please callme on 07759 999303!
Cheers Craig

Sorry Craig, someone's just smashed into my van and it's off the road. I might need to use one to make up a system in a hire van to get me going again.

OUCH Mate! Ok, hope you get it sorted Mark that looks nasty! Hope you ok too mate and/ if anybody else in your van! :o
All the best and Thanks anyway!
-
Ian, what other do you suggest? I tried cleaningspot? one beforeand didnt get on with it, it didnt seem to be as good as the varistrem
???
-
CS are distributors of our controller.
I am interested in why you feel it was not as good - How could it have been better?
The VS is a good control we feel the differences between the the VS and our Control offers more flexibility

Ian, if I may hijack this post a minute. When your controller reaches pressure does the pump stop completely? I thought I had a controller problem (not one of yours). Only my pump can still be heard to run very slowly even though pressure is reached - any ideas?

Hi Mark
I am assuming the control is a digital one with DE (flow off)
Is the controller going into DE? In DE the pump will appear to pulse every few seconds - This is the controller retesting to see if the water flow has been restored.
Also can I ask have you got the pump pressure switch fitted?
-
Yes it's a brand new digital one. The pump pulses as I would expect and all goes quiet when 'p' pressure is reached. However when it's not pulsing I can hear the pump rotating slowly presumably still pressurising the system. Pressure switch disconnected.
-
Ok
I am working on the principle that you want the control to DE (flow off) or hit P (pressure) on the VS
I am also assuming that the flow is cutting of when you want it to. As I understand it the VS
will retest for (Flow off) P every few seconds, the pump will pulse. With no pump pressure switch the controller will continue to retest and in theory the pressure will continue to build. This building pressure may be what is turning the pump.
Now if the control is hitting P (flow off) sooner than you want you need to calibrate the pressure setting on the VS to be less sensitive.
-
It's doing everything it should but why would the pump continue to turn in between pulses? Or why would it overpressure with the cal really low. No evidence of air anywhere in the system.
I just wondered if there was a techy kind of answer that might lay with the pump perhaps.
-
The DE or P retest needs to have some pressure in the system to test against, Each time the controller retests and the pump pulses the pressure builds very slightly.
With a pump pressure switch the pressure will eventually trip the pressure switch and stop the pump completely.
With no pump pressure switch the pressure builds this pressure has to go somewhere so it is possible that the pressure build up will turn the pump very slightly.
In most circumstances we would advise not to leave a control in this flow off situation for long periods of time. as it can lead to damage to the pump and controller.
To be honest to the best of my Knowledge the VS is working as it is designed to. As is the pump by the sound of it.
So to answer your original question with our control because we recommend the pump pressure switch is connected so eventually with our control the pump would eventually stop the pump completely and the control would show PS or pressure switch activated.
If you think you are getting high pressure in the system it is always worth checking from the brush back to the pump and ensuring there are no restrictions EG grit dirt or kinks in the hose.
Also remember the colder weather effects the expansion of the hose and can cause higher pressure and load on the pump.
Hope this all helps
One of the differences between the VS and our control is that our unit will operate with a pump pressure switch.
-
Thanks Ian. I have an on going pressure problem with my system. I've probably mentioned it before on here, where I get too much pressure. I've changed everything I can think of (three different varistreams) all the pipework and hoses. All the calibration settings, all connectors and any o rings etc. The pump is the only thing left that hasn't been changed.
-
Just out of interest what size hose are you using. Some off the smaller micro bore does not work well with the Varistream.
-
8mm
-
Ok just a thought may be worth trying another pump.
-
I got a hydroflo from the window cleaning warehouse about 18 months ago still works a treat
-
I've ordered a new vs earlier, should be with me tomorrow! :)
Ian - I had similar probs to above where the pump just seemed to keep turning over? It may have been faulty but i soon replaced with a vs and never had the prob again.! It did however earn me the money too, so i was happy but it only lasted a year before failing!(should have contacted supplier at time but you know how it is time is money! ;D And i thought it might work differently to vs! ::))
Never mind it will all be sorted tomorrow! BUT..................................
I've learnt another thing from Mark Ettings issues and mine........ It is a good idea to keep a spare vs and pump handy!!!!! ;) ;) I'll be sorting that out asap!!!!! ;D ;D
-
me and my wife run off 2 varistreams and 2 pumps. this way if one goes down, a quick hose pipe connector and can both run off 1. so always got a 'spare' handy! :)
-
Thanks for the feed back on the controllers We have one or two things in the pipeline that will alter how the controller operates when in DE.
Both the VS and our control should pulse the pump every few seconds when in DE or P it may be that some pumps sound a little more noisy than others.
Also as said above be wary about water flows through cold hoses as the lack of expansion during this cold snap is likely to have and effect on how your pump and controller will work.
Take care out there
Ian
