.... what happens when you turn your pole tap off?

Does the pump continue trying to pump or does it cut out?

[Smurf]

It will cut out depending what the pump thingymebob is set on
Just remember it's called a pressure switch 

[Mike55]

I would assume if you connect up the pressure switch using the extra wire and ensure you have adjusted the pressure screw correctly it should cut out fine (for Shurflo pump)

[Og]

Depends on leaks!

[chris turner]

The pumps pressure switch kicks in, problem is it burns the pressure switch out very quickly.
Not sure what I was doing wrong but within 3 days of using pump only the pressure switch burnt out. Put in a new one and a week later that burnt out!
That was using an aquatap on the pole so the water was constantly on/off.

So safer to have a controller? I have the pump on full bore anyway so I just wondered what the point was in a pumpbox.

[Smurf]

At full pressure and flow using hot leaks are guaranteed for sure.

I even have a pump controller on my softwash chem pump so I can adjust the flow depending what I'm doing.

I use a tap on the rare occasion I need to adjust the flow. Won't be hot anyway. Just a little system in my truck to pick up the overflow work until there's enough for another van.

I don't use a controller, I have rectus 21 fitting on end of hose reel. When I disconnect, the pump will just cut out, no problems occur.

[Stoots]

Ive never used a controller, just an on off switch at the van

When you turn the tap off the pump stops with the pressure switch but is still under strain, so will wear quicker,

However I use cheap chinese pumps from ebay, not the 4lpm ones (use those in trolley) you can get 5lpm ones for about 15 quid each

Yes they pack in eventually, ran this way mine typically last 4 months. My system is very simple in general, i dont see the need to complicate it to be honest.

[Smurf]

Adam why not just treat yourself to a decent wfp pump and controller for van use as will last years not months.

[M & C Window Cleaning]

I recon that with a decent controller these cheap pumps are probably capable of a great deal more than we give them credit for. I've had a 5ltr/min one on my trolley now for 9 months and so far it's not missed a beat (that's probably blown it  ). However, it is being controlled by an analogue PWM controller.

If you're talking about a SHurflo pump, they have a built in pressure switch. If you switch the water flow off at the tap resulting in excess pressure the switch will activate and kill the pump. It will not "re-activate" untill you open the tap and release pressure".

Nothing to do with safety. Controllers are there to reduce flow to controllable to what you need. If what you need is less than what the pump produces (if left to its own devices) then obviously its served its purpose, add to that by doing so it will reduce the drain on the battery providing  it. If you want to go full bore anyway, there is no need for a controller. Again, i'll repeat...there is nothing to do with safety by having a controller, just fit an inline fuse.

THats not been my experience. Also the pump is purpose made and designed to switch on and off by the pressure switch. You should be aware that poor wiring/connections will cause overheating. That could be a possible/probable  cause for failure.

Changing a pump every four months is not complicating it ? Ok.

This is why I use one on my trolley. Four small bolts and two jubilee clips, job done. 2-3 minutes. I keep a spare in my motor. And it's less than half the weight of the Sureflo.

I have advocated that using a controller can help make a system more efficient by having the pump produce only the water needed at the brush head rather than flat out. Doing so reduced the current draw of the battery, reduces strain on the pump motor and reduces back pressure in the system.

With the pump running flay out you can have up to 8amp of current being drawn by the pump. This means a high energy load builds up in the Pressure switch. As flow is stopped with a tap the pump will try drive against the restriction. Pressure and current builds up and as the pressure switch opens to stop the pump there is a very high current draw across the switch (and heat) As the switch opens under high load it arcs. It is this arc at high load which blows the pump PS. There is also a high load on the pump motor placing that under strain too. In the course of a day this is happening dozens of times. Using a controller reduces the load and strain on both the motor and pump PS.

That said it is horses for course and people will work in a way that is best for them.

Fitting a fuse is an absolute must whether you use a controller of not. A pump gets hot as do cables and fitting a fuse will protect the system.

Interms of safety and controllers there is one which a has a a number of designed in safety features that protects the system as well as the controller.

It's burnt my pump pressure switch out once in about seven years.

And it cost about £2.50 to replace.

I run without a flow controller for over 2 years . Before I had no end of problems with varistreams.
I run 2 pumps and have had one pressure switch go in the past 2 years .

I bought a load of pressure switches from maplins thinking I would need to replace every couple of months. No need!

Great to have plenty of spares easily carried in van as appose to varistreams .

The flow rate is excellent- feels like you are actually washing windows.

I use the univalve /tubeless system . Works like a dream .
