Dear Reefers,
I need some suggestion on my setup of auto top off (ATO). Due to limited space I can’t fit in the RO water storage tank under my DT, so I have came up with this setup as per in the drawing.
Tap water flow is control by electrical solenoid valve (24V) which is connected to float switch. The valve will be activated (water will pass thru) when the water level at sump reduced via the float switch.
Water will pass thru the RO filter and then to the Kalk reactor, and finally to the sump.
Solenoid valve will off once water inside the sump is full via float switch.
Hope to receive comments (pros and cons) on this setup before I implement it.
