Auto Water Topup..

The third pic shows the insides of the unit.

Forgot to add earlier on that I used a two-pin connector for the mains. A three-pin connector (with a regular 3-pin plug) can also be used instead if preferred.

The fourth pic shows the first float switch which is in the tank.

The last pic shows the second float switch which is attached to the pump. Anytime the water level falls below the float swtich (but still covering the pump), it will prevent the pump from being switched on.

Hi Fantom

May I know the total cost of the floats, pump and your box????

I use the float with the pump only. This already cost abt S$40. I think ppl here would like to have a cheap and efficient device.

Just my thoughts only, hope you dont mind the comments.

Material-wise, it doesn't cost a bomb but the time and effort involved does.

The LFS at Balestier sells their own bare bones unit for about $120 (excluding pumps).

I can do a full featured one for not more than that (more like less), inclusive of parts and labour, if anyone is interested. Actual cost will vary depending on features wanted. Please note that I don't include pumps - it's not appropriate as people would require or want different pumps based on likes and needs.

If anyone is interested, please PM me. But please note that I will be away from 17/11 - 25/11 (that's why I made this unit :-) )

Adrianli,

I suppose you connect the float directly to the mains? In my design, I don't do that. It's rather risky doing that. The float switch may not be rated for 240 volts in the first place. Should there be a short, nasty things can happen. I pump in only 12 volts to the float switch - you won't get an electric shock with this.
