Anyone have any experience with THIS pump?

I'm going to use it to fill my toilet cistern from my rain water tank, given that it has a flow sensor I imagine that it should be a pretty simple setup. Straight from tank to pump to toilet. Ball valve drops, flow starts and pump kicks in until ball valve closes and flow stops.

Will probably put a valve of sorts in at the toilet to switch between mains water and rain water, depending on whether there is water in the tank and in case the electricity runs out.

That pump is used to create and maintain pressure. So yes, it would be perfect for what you want to do if the JOJO is lower than the cistern. The ball valve in the cistern will cut once it has enough water and the pump will maintain water pressure till the next flush

Edit: Yes you ware right, pipe from water tank to pump, from pump to Cistern. Add power to the pump and Bob's your uncle.

I see JoJo has a submersible pump as well, wonder how that would compare to the booster pump.

You need a pressure pump. Else the water won't make it to the cistern. Submersible pumps just pump, they don't maintain pressure. It will work but you will have to manually put it on and off to full the loo.
 
The booster pump is dead simple to connect. I've got a different brand but it is identical and the same setup and installed mine over the weekend. Mine pumps water throughout the roof into my garage without issue.

The pump will switch on immediately when it detects a tap is open and will run for 2-5 seconds once the tap closes to build pressure.

Important part is to run the correct thickness pipe to the pump, 25mm. From the pump you can run 15mm. You can use polycop as there is not much pressure.
 
Great, thanks for all the info - think I'm going to go ahead and get this in.
Just need to find a decent valve that I can put into the bathroom that will allow me to choose where my water comes from.

There is a bylaw issue with that. You need to checks valves installed to prevent water contaminating the municipal supply. https://www.builders.co.za/Plumbing...Valve-Spring-Type-(15mm)/p/000000000000366187

My setup is for my washing machine and dishwasher and we disconnected the pipes from the municipal supply. If the tanks ever run dry I can always fill the tanks manually or reconnect back to municipal supply.

For our toilets we use MyWaterLoo (http://mywaterloo.co.za/) water banks and just manually fill them with rainwater. The one cistern has been removed from municipal supply as I tossed out all the internals (old toilet) and the other is switched off at the stop cock. I'm also considering connecting these to the pump directly and removing them from municipal supply.

Reality is we are stuck with DayZero until at least next year winter so no need to be able to quickly switch back to municipal supply.
 
Be careful with the valve: I'm planning to do the same, and plumbers I've consulted on this say it has to be a specific grade of non-return valve so as rain tank/other water doesn't back-flow and potentially contaminate municipal supply. There are standard non-return valves available but apparently it has to be what's called an 'RPZ' valve, of which there is limited supply. Fitting this can also in some cases invalidate your building insurance unless correctly fitted by a plumber, so check this side of it out too.
 
I'll probably get a plumber to do the install for me, I can do most DIY things - but plumbing is not my forte.

Or have a float switch in your cistern.
