Pump straight to battery?
« on: December 20, 2022, 04:43:46 pm »
Hi all,hope everyone is well.My flow controller has just packed up on me.The supplier said they’d take it back and check it out but that’s going to be a slow process over crimbo. While they’re looking at it all I can do is connect the pump straight to battery.Any thoughts on this?I don’t want the water to be on full blast so was going to control the flow with the hose tap.Don’t know why but I’m concerned that this might overly stress the pump and knacker it out.Any thoughts appreciated,thanks in advance 👍

Absolutely fine, i did this for years, you will want the pressure switch connected though otherwise you`ll blow fittings. You can also adjust the pressure switch if needed.

Theres not really any need for a controller other than save your battery.

Youll probably find you work much faster with flow on full whack and prefer it.

Yeah unfortunately this doesn’t work with employees I would wire the pump up like this on
purpose if that was the case 😂.

Thanks folks.
Stoots,I’m being a bit of a div here but not sure what you mean about a pressure switch?I’m aware that the pump itself (shurflo) has a pressure switch but beyond that I’m not sure what you mean.

He means the pressure switch on the shurflo pump.

Just a bit of advice to all. Buy at least 2 of everything just in case of a breakdown. It saves on down time. I've got a controller and pump both brand new (they were brand new) sitting in the garage just in case.
We look at them, they look through them.

At the bottom of the pump craig does it have two wires going into it?

Make sure it does, and that’s your pressure switch. Some times people disconnect them when you are using with a controller. You don’t have to though.

Thanks again for the input folks.Yes it does have the 2 wires connected so hopefully I’m good to go 👍

I did it for a few days without any issues whilst my controller was away being repaired

Hi Craig.
In the short term this will be OK. you may see higher water usage and it us the pump pressure switch that will stop the pump when the valve is closed. The pump will also run hotter than usual and battery current draw will be higher. The battery may need charging slightly more often as you will have no way to check voltage that the controller would usually display. Also keep an on hose connector joints as these may be under more pressure than usual.

Also Can I ask what controller it is and what happened to it 

Cheers

Just don’t use a tap or dead end the pole until you get back to the van and turn the pump off,I know people that have run pumps like this for years the only thing is you’re pump will last half the time.

I had to do this for two days earlier this year due to controller suddenly packing in and no spare.
Worked fine in fact it was actually making me quicker on full flow.
And it worked fine with univalve.
Impossible done straight away, miracles can take a little longer.

Yes my pump has only been running for nine years with a tap and no flow controller so far ...  ;D

You’ve been lucky controller~tap etc although they easily last that long once changed you realise how much use they’ve had,I get the same flow on 50 I was getting on 99 now.

I have two pumps. One per reel though swappable through John Guest piping and taps. My favoured pump gets 90% of the usage. Both pumps still have similar strength.

Thing is you don’t realise how used the pump is until you change it I’m not saying you don’t know this you obviously do,first thing you realise is how quiet it is I had to touch and hold my hand on top of the pump to see if it was pulsing and the pressure and flow on  half was the equivalent of a flat out worn pump.
