Faulty pump, controller or something else?

[SPECI4L]

I'd previously been running the flow on 55-60 but without warning this became far too high & I was running out of water over the course of a day.

I had to drop flow to around 40 to get a similar flow, since I changed the battery a few weeks ago this setting has dropped even further... I'm now down to 30 & getting a similar flow to 60 from 6 months ago.

Throughout the day the water will randomly stop as if it's dead ended but no DE on controller... up the DE setting a couple & we're fine.

Flow can vary through the day too... 35 can be a little under what I like to use then 15 mins later I have to knock it down to below 30 & it's blasting out of the jets!

Apart from the battery, nothing has been changed in my system.

As the title suggests, I'm trying to figure out what's duff & needs changing before my head explodes!

I don't know tbh.

But the viscosity of the water has changed as summer is approaching and the water is definitely much warmer than it was a month or so ago.

Many dams and reservoirs are also low this year as we haven't had the winter rains, so the water has warmed up much quicker than normal. I doubt it would increase the flow by double though.

Maybe the controller is on its way out, maybe your new battery is delivering a higher voltage. I would just reduce the speed of the controller and ignore it. If its a fault it will soon show up.

We often had electrical fault issues in the motor trade that only appeared when the customer was miles away. Much like a toothache and visiting the dentist. It always goes away when you get to the dentist. Often we suggested that they leave it be until the fault got worse or it failed altogether. It would be easier to diagnose then.

These sort of issues tend to end up being faulty connections or a bad earth.

You could try wiring up a cheap PWM controller like many use off ebay. I've got a mate who swears by them. It won't cost a lot and if your problem goes away then it's likely your controller was the problem and you haven't spent a pretty penny only to discover it wasn't your controller. Then you can decide whether to carry on with your cheap controller or fork out for a new digital one. It is a bit odd that your flow should be getting faster as generally when things start to go wrong it seems to slow down, go intermittent or stop.

numbers are good as a reference but mean diddly squat in real terms,your flow rate with the same number would be vastly different to mine, the roberts number comes into the equasion many many times,

my first thing to bin would be the controller imo,denby on here or da components as daz is known makes a solid,reliable controller that would work better,the spring ones aren't always the best for some people,re-connect all the wiring helps to solder the connections if you can,it helps massively re:resistance in the circuit,as spruce has said the water is a bit warm for the time of year so the de would need adjusting but not everyday-best to do away with it altogether-one less problem to deal with mate

Are you getting airlocks in between driving to jobs if you don't disconnect hose from hose reel to check then that could be causing a issue.

I have a flat tank so first thing on a morning and 2-3 times throughout the day I will run the pump flat out to get rid of airlocks.

Thanks for the replies fellas, I should hopefully be able to figure something out.

It's defo not airlocks @Iron Giant, I use a trolley so I'm pretty good at getting rid of those now. lol

How long have you had your trolley now if its a 4-5 years old then it could very well be the controller starting to play up as I found with my last 2 controllers they lasted a few years.

It's about 4 & 1/2 years old... I was wondering roughly how long controllers last.
