Very nice! Good job!

Can you show me more though? ;D Im not sure how you are draining/filling automaticly. Im getting geared up to automate my fishroom and all the tips I can get would be appreciated.

Thanks!

Hi:
The images show the way to put water in the sump...to put out the water I use a litlle pump inside off the sump with a electrical watch programmed to daily put in work the pump.The pump connects to a tube,to empty the water I pretend.First I empty the tanks through the pump,and then +/- 15 minutos later the water start to fill the tank.Very easy,without any sophisticated system.

Later I post new photos!

Best regards

For months now I have been planning on testing out this sprinkler solenoid valve and finally yesterday I did (now I only wish I had done it sooner > ).

First the background on my system:
- 250G storage tank with 2" PVC running around the perimeter of the room
- Aquamaster 2400 (can you guess what its for)
- at each sump location, the 2" reduces down to 1" ball valves
- I can fill multiple 40G sumps in under a minute

How the s-valve works:
-***the valve opens when there is power. Power must be on to keep the valve on
-***the valve is closes when there is no power

What I want to achieve is a good flow rate so I compared the flows rates with the s-valve to that of the flow rate with just straight pipe (nothing hindering the flow like flow valves).

I only tested the fill system so far. My first test was just connecting the s-valve as is. Flow rate was about half of the capacity. My second test involved taking the diaphram spring out (the spring assists in closing the valve). The flow rate improve to around 80-90%. However the shutoff took 6-8 seconds longer that the first test.

This completes the biggest hurdle in my automation system. I really didn’t want to spend $300+ on 1 solenoid valve. These valves run around $20cdn each. Next step is setting up limit switching (hi level, low level) and programming. ;D
