i have a sureflow 100psi pump that was used with a varistream. now it isnt and my only problem is the pressure switch doesnt kick in when i stop the flow. i think the pressure switch has been disconnected and i am just wondering how to reconnect the switch

thanks stuart

anyone

Whats the pump being used with now

[Dave Willis]

Matt will tell you 

There should be a plastic connector that clips on the pump head with a couple of wires coming out of it. Maybe it's been taken off?

[R W C™]

If your thinking of undoing the pressuere switch then becareful as you dont want to lose the spring that is underneath,

[BORBRYCE]

I think your switch is doe doed Stu. They are quite cheap to replace.

[weetot]

Dont lose the spring

the red wire from the pump connects via a spade term. to 1 side of the switch, the other side has a red wire (prob taken off) this goes to power.

hope this helps

thanks thats what i needed to know so i dont need to strip anything off the pump to fix then

its being used with a bypass which is much better in my opinion.

ronnie nothing wrong with the switch its just not connected, i have replaced one before for pennys

Hi Stuart,

do you have a pic of your bypass please, as I have a brodex pump that I would like to do the same with.

Hi Stuart,

not got any pics at the moment but you just put a t piece either side of the pump and put a loop of hose with a flow control in the middle

[Central Window Cleaners]

Thanks for that, if I dont manage to sell before end of auction I will give it a try.

thanks stuart

if you are using a bypass , the pressure switch will not activate, as water will circulate around bypass when you stop the flow, thats one of the reasons i dont use one, as the pump would be running all the time, until it is turned off.

yes i know mate it doesnt bother me that it keeps running. i only want to reconnect for the rare occasion i turn the flow up full because this stops the circulating

[Peter Fogwill]

I still connect all my pumps up with a bypass in case anyone wants to turn the flow down for any reason.  I would personally use it on full power all the time as it is faster that way to clean a window. 

I would also recommend anyone not using a flow controller to fit a relay to the system.  A relay is around £2-£3 and you all know what a flow controller costs.  Even if the pump cycles the relay takes the hit rather than the pump switch.  These relays are heavy duty compared to the pressure switch, after all how many times are they stopping and starting the power going to a cars indicators in their lifetime.  And if they do need changed then 30 second and a couple of pounds and its done.


The flow controller was introduced to save on replacement pressure switches, and the relay does exactly the same.

i agree totally peter and i will go say the same on the other forum. in fact we all learn all the time in this game and in one sense i should have stuck with the pump you supplied in the first place and not wasted money and time mucking about with flow controllers. but i always read about the controllers that much that you get thinking that may be way to go. but its not in my opinion  keep it simple is my way

I got a varistream years ago when they first came out for the same reason you mentioned, and I was told it was the only way to go.  I never got round to even connecting it up because I never seen the benifit of it, and especially when I started reading all the posts about people having problems. 

If one of my customers has a fault with their pump I can put my finger on the fault after asking a couple of questions, and their new part is on the way.  I wouldn't be able to do this as easy with a flow controller in the equation. 

The one I had gathered dust for many years until I had someone having a van system fitted recently, and he insisted on a flow controller.  There was no talking him out of it, but I did give him it cheap, with no guarantee on it.

Let me know if you want to connect a relay up to your pimp, it is quite easy.

I'd like to know how to connect a 'relay' to my pump (even though I haven't had any problems with the pressure switch, yet!).   Also, where do you buy the 'relay' and what (rating?) do you ask for?

Also, you say - "Even if the pump cycles the relay takes the hit rather than the pump switch".

Could you explain 'the mechanics' of what happens when using a 'relay' in conjunction with the pressure switch, as I don't understand.

Thanks.

Mike

[Peter Fogwill]

Mike. have a look at this page it will explain it better than I can.  http://wiki.answers.com/Q/What_is_a_relay_circuit

I know for a fact that with the relay fitted I send out no pump switches, and before I started using the relay I was sending them out on a regular basis.  When wired into the circuit the relay is stopping and starting the pump and not the pump pressure switch..  The relay has much bigger contacts in it than the pump switch, and less likely to burn out.

I get them at Maplins, and I will post the part No, and diagram when I get the chance.
