[1] You will need to charge your battery regularly, if not daily. If you don't then the pump speed controller you just fitted will continue to run until your battery is dead. So you could end your batteries life prematurely if you're not careful.
We've never had this issue. I'm not sure I understand. Could that be because we fitted a simple on/off switch?
[2] Unless you start adjusting the pressure switch on your pump then your whole system from pump to tap (or brush head, depending how you operate) will be primed at 100 PSI. So make sure all your connections are really watertight. Operating like this will find the weak spots.
I'm not sure I understand this either. You've got to adjust the pump pressure switch. It's very simple, you just set everything up and turn on the pump and adjust the hexagonal nut at the base of the switch so that it turns the pump off the moment you kink your hose (or what ever method you use) to stop the water flowing out of the pole.
It's simple to do and it only needs done the once. Unlike the flow controllers I've had before where a change of temperature could mean recalibrating the controller.
Tosh it will depend exactly on what the operators are doing. Lest deal with [1] 1st....
If you're operating with the above motor speed controller then how long are you working the pump during your day and how often are you charging your battery, and how often is there more than one of you working the same battery ? Do you have a voltmeter to tell you how low your battery is going or do you carry a spare battery just incase. Or do you not have a problem with any of it ? And how long does a battery last you ?
Just to add.....there's a current richywilts thread about batteries where the advice ranges from charge everyday to be sure..to "i charge mine every three days" .
What i'm getting at is , are you just running for a few hours a day and carrying a spare? (like me) Or are you hammering it, two of you all day from 8.30 to 4pm? I operate the former and my current set of batteries is in its second year ,i use a controller,and i charge a battery about every five days. My friend who operates the latter has to charge everyday, he has burnt out several pressure swithches on his sureflos, he has gone through several "controllers", and has ended up with these motor speed controllers. gets through more than four batteries a year . We've also found that the motor speed controllers heat up when in continuous use to the point where they melt the plastic box. They still work fine, but they do generate some heat.
I suppose in short i'm asking ..have you ever run your battery out. If not, why not? WHat do you have to prevent that happening ?
[2] I'm not sure if we're at cross purposes here. Straight out the box a Surflo is generally set at its max, 100PSI. Turn your tap to off, or kink your hose it stops the flow. The pressure quickly builds up to 100 PSI and it shuts off? yes? I use a tap. So thats my whole system sitting pressurised at 100PSI, yes? Water now starts dripping out of my hozelocks, not significant to cause alarm, but it drips out. It makes my van wet and causes my pump to kick in every now and again as i'm driving along. If i use a controller i can set the calibration of the pump pressure to say...30 (on the dial), i assume that means 30 PSI, although i'm not certain, but it sort of makes sense to me anyway. This means when i shut my tap off there is 30 PSI sitting pressurised in my system? I don't get the leaks or drips as i'm driving along and my pump does not kick in every now and again to make up the lost pressure?
If you do not use a pump controller, and just use a motor speed controller and you want to lower your pump pressure then you have to unscrew the two screw on the cap at the end of your pump, and then adjust the screw in the end of the pump ?
