I have an underground water tank that is not pumping water so I’m using mains. I think the issue is the sensor in the tank, but I may change the wall switch and tank pump too…I can’t get a plumber out to do this, I don’t know why. Perhaps it’s too messy a job. My question is, is changing the pump in the tank difficult? I believe I can change the wall switch myself. Based in Australia

Yep get a new pump and operating float (make sure it's not a signal float - pump rated for amperage equal or in excess of the pump's FLA). Pull it out, plumb the new pump in with your ball valve check valve union as they presumably did there. Probably need some pipe a few male adapters some primer glue etc. You'll see what components you need. It's tough to plumb out of the hole usually you evacuate the tank then plumb so it all fits but still can be done. Make sure your check valve is on the discharge line below the ball valve so you can isolate it. Check valve is a must make sure it opens with the discharge flow not backwards.

Thx. What do you mean no signal float? Also is excavating the tank necessary? Mine is made of concrete

Not at all on digging up the tank.
And a signal float is intended for a control panel where it sends signal to a relay etc for a control panel. Not enough juice to run a pump... CV byBut if you just tell them you need a float switch, that's what you're going to get. You need to tell them you need a wide angle pump rated float or an operating switch.

What kind of water is it pumping? Sump pumps are dead easy. If you undo that union you can pull the whole pump out. Buy a new pump with the same dimensions, spin the MIP out of the pump, Teflon tape it, spin it into the new pump and put it back in. You might also find out that the pump is just jammed or only need to replace the float.
Edit I see it's pumping rain water into the house, cool what for?
Anyways I'm surprised you can't get a plumber this sort of thing is easy money, you should be able to figure it out yourself.

It’s rain water for the toilets, washing machine and yard taps. When making the replacement should I empty the tank?

To my knowledge, you split that pvc union right there and pull the whole thing out. The ones I have experience with often have a pull rope right on them
