I was hoping someone could help me figure out what is going on with my pump controller. I hook my wires up to my battery and turn the pump controller on and it starts pumping at the rate I have it set at which is around 20-25. I go to my pole and start working I will be half way through a window or two and the pump controller starts reading 0 instead of 20-25. The lights are still on on the pump controller. But no longer any pressure. I have no idea what is going on it just started doing this everything had worked fine before. My tank is full, it’s not reading like I have a short, it’s not kicking off the power so I don’t think it’s electrical. So I feel it’s either the pump is going bad or the pump controller. Not really sure. Any ideas? Obviously I understand u may not understand my setup completely. I’ll try to post a couple pics.
So these photos where taken within just a few min and you can see the pump controller goes from 20 to 0.
I dont have that controller (have you checked the manual?)
Sometimes with my controller, it stops intermittently or completely the flow/pump (but controller stays live/on) it’s usually a flat or low voltage battery.
You dont say it stops, just no pressure… so not sure if thats what you mean?
So in your experience chris how long should a deep cycle battery last. Mine is just a year old. And I use it between15-30 hrs a week sometimes less. Charge it maybe once ever week or two.
I use a 110AH leisure battery.
After a full 7-9 hours continuous use of a day i could have discharged most of it. But that depends on the load you are draining it at…
My battery is on a split relay charger in the van, so gets charged as i drive, and then it also then gets benched charged every weekend, and more during the week after/before bigger jobs.
If your controler is not pumping you should have a reading on the screen. Like DE for dead end or a blocked hose or fitting somewhere in the line or a Bat for battery needs charging.
So why calibrate the controller to a pump?
What we are doing is telling the control what the maximum pressure the system normally operates at. To get a good flow at the brush head the system is probably running between 40 - 70 PSI. So the control knows that the normal max level is 70 PSI. When a user stops the water flow the pump will attempt to push against the restriction increasing the pressure above 70 PSI the pump sees this sudden rise and stops the pump. This is what we refer to as DEAD END (DE).
During this DE (flow stopped period) the controller periodically retests the pressure at the pump.When the restriction is removed the pressure falls back below the 70PSI maximum and the controller restarts the pump at the preset flow.
The control is designed to stop the pump before the pump pressure switch activates where the water flow has been stopped. A pump pressure switch may activate at 110PSI give or take (based on 100 PSI pump) as described earlier running the pump to these high levels can cause problems.When flow is stopped The pump draws a spike of current and the pressure in the line builds. Calibrating the control to the system means the control knows the usual PSI and current draw. When flow is stopped both these spike. The control sees this and stops the pumpIf there is air or a blockage EG blocked jet, pump pre filter. Other causes can be 90 degree angle adaptors or differing sized ID connectors, Check for any jammed non return valve.
I am available 24/7 by text phone IM Voxer Facebook messenger or WCR or @John
Hey john thank you for your response I really appreciate your experience with these things. I think I’ve discovered my battery was not charged completely. My voltage was at 10.4. I put it on a long charge last night. And post weather that fixed the problem. If not I’ll progress to weather there are blockages or other suggestions made. I appreciate your help.
Anytime you need help just contact me.
thought as much… always first thing i check when i get pump/controller issues - it gets so easily overlooked.
