Battery dirty water pump

I’m installing septic tanks and treatment plants at a rate of knots at the moment . I usually hire a self priming pump for wet installs or go like feck and try to get it done before the water gets above my sump hole .
Either way I was wondering does anyone make a battery pump that can lift water from a sump hole . I say dirty water but it’s usually fairly clean sometimes with a bit of silt in it . It wouldn’t matter if it was self priming as it could be just switched on when the water rises to a certain level .
I’d like something small enough that I can keep in the van permanently so not a petrol pump .
Anyone used anything like this ?

Not 18v but Makita do a tiny little 2 stroke pump. Can't imagine even a battery one being any more compact.

I’ve got a little Honda 1” pump really handy for these jobs only as big as a football but pumps well

I have used 12 volt bilge pumps to pump through a 3/4 hose, they don’t really like pumping silt but they are ok if you keep them from sucking the bottom of the sump.

Do you need to prime it every time you start it or does it self prime?
If pump chamber empty then put a small amount of water to cool, kink the output seems to self prime, can prime it with 2 litre bottle.

Also got 2” trash pump but 240v and on a float switch that works well but 240v

Other option is a JCB hydraulic one off the breaker circuit but might be a bit of a nuisance to connect every time you need it

No use, back pressure kills them quick. Needs direct to tank or a beaver pack.

Sounds great in theory but you tie the digger up which could be backfilling as you pump. 110v submersible and a genny if you can't run leccy to where you are.

If its just smallIsh amounts of water, I’ve been very impressed with the Milwaukee 12v pump stick for emptying the bottom of footings etc. it has a pretty good filter system at the bottom of the stick. Worth a look, wins for me on convenience and is also pretty effective.

Basically if the water is coming in as you dig then you need a petrol diaphragm pump. But for pumping out once or twice a day then the pump stick and possibly a cable tie for the trigger is pretty nifty. It may even have a lock switch, can’t remember.

By far the best price I could find and they had stock:

I have a compressor which runs of the vehicle battery- it puts up a tyre in no time. Would have thought a pump running off the same could be handy.

I've seen a vid online somewhere of somebody pump water with makita cordless leaf blower by putting a pipe on the intake but i don't know how long it would last 😁

Got one of them too. Works really well. Lightweight, easy to handle and Honda reliability :)

Well speak of the devil. Guess what I got called out to today?

We all know what customers really mean when they say ‘yeah, I’ll shutter it’. They mean ‘I won’t shutter it and I won’t bother calling for concrete for a week’ most of the time!
