the only problem we have had is with the latest one is that it needs a seperate isolator switch to switch everything off at night or it just drains the battery.

I enjoyed reading your well thought out post, Spruce, as they normally all are.

But I have a two man system using two different flow controllers.  My Cleaning Warehouse flow controller worked perfectly (still does), but the Varistream gave me no amount of problems.  I'm glad I knackered it by connecting up the polarity wrong, because I prefer working without a flow controller.

It took about five minutes to wire up the pressure switch again.

Hi Tosh,

I know that Nat prefers to have a controller that is still operated by the pressure switch which he adjusts lower and an electronic speed controller only so he can regulate the motor speed and hence the flow. I quite like this idea as the 'on' action of the pressure switch is immediate, where we find that we can wait a few very long seconds for the electronics to start the pump again which can be annoying. That's just minor though and I'm starting to get too old and slow to let it rattle me too much.

Since those early days of Shurflo pressure switch failure which was an expensive replacement part, we now know of the cheaper Maplin alternative, so a burnt out switch is not that much of an expense any longer and, after all, it is a wear and tear item.

With Nats concept, a pressure switch won't be doing as many cycles as it would normally do, so will last longer anyway.

Flow control starting flashing 'bat' this afternoon - flow became very intermittent  
Put my charger on battery when I got home and it's showing full charge!!

Any thoughts/help appreciated
 Thanks  

On hols so a bit slow picking up on this. The Controller will flash BAT if it detects 11V or less.

If the battery is showing a full charge and is undamaged I would suggest you check the following

Ensure the cables are as short as possible between the control and battery - Pump Cooper does have a resistance factor so the longer the cable the greater the volt drop along its length.

2. Check all the connectors replace any corroded ones
3. Check all the cable for any damage replace damaged cable
4. Avoid using tape to make connections as these will pull apart again causing a volt drop.
5. Consider a new battery

Other factors are a worn pump motor which may be worth considering

With the poor flow recalibrate the controller and also check for any air blocks or other blockages

Cheers

Recalibrated controller this morning - everything seems to be working fine now!!
No probs at all today 
Gonna look at the wiring at the weekend now just in case - probably early warning signs of pump failure or battery ??

Can't work out why it's fine today tho?

It may have been a loose connection somewhere which once the battery went back in was sorted.

I have tried to cover some issues with an FAQ page on our site http://www.springltd.co/faq

Glad all is well for now
