Here is where the sump return pump drains the water from the sump out through the wall to the sewer drain. The other two pipes through the wall bring RO/DI water and Salt water from the garage.
The Maxi-Jet in the skimmer section and the refugium pump water into the return section during water drain so I can change 60 gallons of water.
These are the two 65 gallon barrels in the garage. There is now a RO/DI unit above the water heater. The top barrel is RO/DI water. The bottom barrel is Salt water. Via an in and out manifold, one pump moves either salt or RO/DI water through the two pipes to the sump.
Here's the RO/DI.
Here's the path from the garage to the sump.
