Hi all
should the variestream 2 stop the pump from running when i diconnect the pole on the stop valve .
i have had problems with pressure build up in my system and connecters popping off . as the pump just keeps on running .and i thought it is supposed to stop the pump. ???
-
I had similar problem and phoned Williamsons up after the top blew off my di - in fairness the threads weren't the best and I had a replacement ready
They told me that the pump continues but only builds to 75psi before recyling the water - I think that meant releasing the pressure and letting it build up again
All the same, I got told before I bought the pump and varistream, that I could leave it running for hours on end (with no water flowing) with no probs - unfortunately I cannot be so confident and tend to leave the hose disconnected for no more than a minute or two
when I reconnect the hose after much longer, it is a bit tricky and I get a good blast of water
They said to call them if it was still a problem but I don't fancy experimenting - too much like playing with a time bomb ;D
-
75 psi seems quite a lot under sealed pressure . can all hoses and conneccters stand up to that . i thought it would sense the flow had stopped aand shut off a lot lower than that.

Dave I have a stop tap at the end of the hose when I stop the flow, the varistream stops straight away and no peasure build up at all.

just a thought you did bypass the switch on the pump?
Roy
-
yes i have disconnected the wires to the pressure switch at the top of the pump and just use the 2 wires coming from the bottom of the pump straight to the controller

Inside the varistream there isa little blue turning switch, it is in increments from a - j, turn it down a notch or 2, this will cause the varistream to cut the pump at a lower pressure.

i have just noticed the red power light is not coming on even with the switch turned right down and pump stopped the green pump running light is on all the time.
there is a sticker saying warranty void if opened so i do not want to do that yet
-
Roy - is yours the mark 2 varistream - if you are getting it to stop with a shut off tap it should be the same for the stop valve - also what pump are you using - I got the sureflo 100 - bit of a puzzler this :-\
-
i got the sureflo 100psi to ???
-
Mine iss a mk1 and a 100psi flowjet pump. stops dead evry time I turn the flow off.

Had the very same problem...as I also have a stop tap at end of hose and once I turn the pump on in the morning I leave it on all day.
I reconected the pressure switch and to date works great..
my green light stays on, why don't know.. I have 100 amp hr battry that gets carged over the week end and it now last,s me all week.

you are correct about the blue dial inside the controller .i have just phoned williamsons and they have confirmed everything you said .
the controller is set up for different pumps and should be adjusted accordingly .
thanks

I had problems with mine not cutting out when i first got it.
Phone williams pumps they told me how to turn the pressure down but adjusting the blue dial inside.
Have had no problems since disconnect a hose or pinch the hose and it's off straight away
Mine is also the MK2 model.
I wouldn't be without it now

Dave, I must have got the office cleaner when I phoned Williamsons - will you let me know how you get on and which setting you choose inside the Varistream - I'll have a go later today - it's gonna be Danger UXB all over again :'(
-
Installed mine yesterday ....works excellent. i ahve 60psi pump and works great.i have dial set to half way and i done a job today that normally uses 3/4 of a 700ltr tank used half so all in all great bit of kit

i have just set to `c` that is all my connectors can stand before 1 of them starts to leak i have 100psi pump.
to test put short hose to your outlet with a auto stop connector .it saves waiting for 50m hose to pressurise .
then after 2 mins the pump should stop .you will hear the pump start to operate for a split second every 2 secs then after 10 mins of leaving the pump powered but not running. the pulsing was every 10 secs .
if you dont fully understand email me and i will give you my number.

Cheers Dave I did understand that, and that's a good tip about the short test hose - I should have known it would be C cos that's what I used to put in multiple choice when I didn't have a clue what the answer was ;D
-
well i will see how i go on "c "
it should be good enough ,
i tried with 50m attatched but you have to wait for ages for it to pressurize
i will see how i get on tommorrow.
dave
-
Used it on "c" all day ,and it worked fine for me .no problems at all .well behaved :)
-
mine is alot higher than "c", but have been meaning to turn it down as you get so much pressure built up it is hard to get your hoselock to snap in!

The Varistream is, among other things, designed to act as the pump pressure switch and turn the pump off when the system is deadheaded. Unfortunately many different pumps are used on systems, so to take into account all options the Varistream is fitted with an adjustment to adjust the shut off pressure (the small blue pot inside the box).
On the vast majority of systems, the factory setting of this unit will suffice, however on some systems this setting may need adjustment to tune it into the relevant pump.
Adjustment is made by turning the small blue pot one increment at a time, to increase or decrease the shut off pressure. Normally a one or two increment adjustment will be enough.
This feature will be added to the Operating Instructions.
If anyone wishes to discuss this adjustment, please ring Williamson Pumps on 0845-226-3638, who will be happy to advise.
