How could I wire this?

[Maebh]

I have no idea when it comes to electrical stuff, but I want to wire an auto water changer. Not completely automatic, as I'd set it up weekly, but automatic enough. Bucket #1 fills with tank water, the float switch activates, it turns the pump on (which is in bucket #2) and new water is sent into the tank. Im thinking the plug sends electricity to the pump and the float switch acts as an interuppter?
Would the pump I chose be okay for water?

is this to be set up scheduled for certain days or times or just when you want it to work?

I'd be filling the buckets and plugging it in myself once a week. Small space so I cant have much kit out full-time

No.

You can not plug a 12 volt pump into a 230 volt outlet.

Absolutely DO NOT use that pump. It is designed for Petroleum products, it will CORRODE in salt water. There is a reason why nearly all the pumps we use today in Marine applications are made of plastic with ceramic shafts, those can't rust!!

Pretty much but I would use a regular aquarium pump and use the float switch to operate a relay, not power the pump directly

Okay, good to know I was also thinking of using a car battery or a ac/dc converter?

12v wall wart will be under 10 dollars. If you are just looking to recycle something you may have laying around I would use a computer PSU.

But would you use a diesel fuel pump?

No. They are usually mostly bronze internals. Also going to be very inefficient.

How does bucket #1 fill with tank water? What stops bucket #1 from overfilling?
