just a quick one my controller has gone chips is it ok to connect pump straight to battery for a couple of days or could it damage the pump when I stop the flow of water cheers in advance

[P @ F]

You can run it but you will have full water flow at all time plus the system will run up to the full 100psi
Make sure all connections are strong and you be good

[gregmyster]

cheers thanks for that ,I just kink the pole hose to stop the flow will the pump just stop pumping then or will I need to turn of the power to stop it cheers in advance

I operated like this for a long time prior to getting the controller, the pump will stop when full pressure is reached. It will be fine.

[P @ F]

As above , once the hose is pinched the pump will get to 100psi and the pressure switch will shut pump down until such time as the water is flowing again .
Be aware though that operating like this will wear the pressure switch much faster so get another controller as soon as you can

I just use the £8 ones on eBay, great little things , I bought 2 a few year ago and I’m still on the first one !

cheers thanks for that everyone I am going to order one of those of ebay later ,I have just tried it with the wires connected to the battery and it worked good I will have to work a bit faster for the next couple of days that's all or finish earlier when I run out of water thanks again

. Do you get instructions in English though? I bought a reversing camera and a hands free earpiece that were Chinese and the instructions were in Chinese only. I contacted the seller to ask if they had English instructions and the answer was no.

Your pump likely has a screw on the end of the pressure switch to manually lower the pressure setting. Turning it counter clockwise normally lowers it. This will take some of the strain off the pressure switch while running it flat out. You likely don't it need set more than 50 psi for everyday use. I've used one with a 40 psi setting before now with no problems, even doing three story houses. You'll know if you have set it too low as the pump will cycle on and off by itself when you're using it. if this happens just turn the screw the opposite way until the pump only turns off when you fold your hose.

You don’t need instructions , it doesn’t do any calibration or any of that !
It’s simply power pos and neg and motor pos and neg, it’s even written on the PCB which is which

I'm now using one of those (on your previous recommendation).

Works great; cheers.

Inside the box it tells you which power cables go where and which pump cables go where.

It's very simple.

I did it and I'm a Geordie.

It would however be a very good idea to carry a spare pressure switch for the pump as the controller does not dead end the pump as the more expensive controllers do .

I have been going 15 years now , my present shurflo is 12 years old  and hasn’t had a pressure switch yet , but I always carry one in case !

[Granny]

How would that work if you have a digital controller goes dodgy?
I believe there is no pressure switch in the pump when you use one of those controllers.

I haven't used a flow controller for over eight years.

A little tip I learned on here years ago and that has served me well is the following.

If you use the pressure switch on the pump to operate a 40amp automotive relay (instead of the pump motor) and use the relay to switch the power to your pump motor, you will likely never have a problem with your pressure switch burning out as the relay is far more capable of switching the power needed without burning out.

The current needed to operate the relay is about 160ma. The switching current of the pump is more likely to be 6amps or more, which is why the pressure switches sometimes burn out if running without an electronic controller or with just a plain PWM controller.

I operate like this all the time, new pressure switch from ebay £3.50.
I don't think I'll ever own a controller, i havent had one for the last 10 years anyway

I have mine flat out all the time anyway I use a controller obviously because it powers the heater and those settings,if I was cold only I would just run it flat out anyway.
