| Water Change Valves
Valve 1 Main valve, Controls water to my sumps float valve, & water change valve (valve #3)
Valve 2 Storage tank drain, Used to drain the storage/water change tank for cleaning.
Valve 3 Water change, Used along with main valve to drain new water from storage tank into the sump.
Valve 4 Sump overflow, Runs to floor drain incase of sump overflow
Valve 5 Sump drain, Drains sump to its minimum operating level of 3”
To do a water change I fill the 20gal storage tank up with RO/DI water. Once the storage tank is full I close off the main valve #1 , then mix my salt with the RO/DI water. I have a small powerhead & heater in the storage tank so after the newly mixed salt has aerated & heated overnight & I have checked that it matches my tanks water it’s ready to be transferred to the sump. Now this is the hard part LOL. I open up valve 5 which drains the sump to 3” (which is still enough to keep my pumps & heater running) after the sump has drained I close valve 5! Then open valves 1 & 3 which transfers the new water to the sump thanks to good old gravity. This just happens to be my sumps running level also! Then I close valve #3, refill the storage tank with RO/DI water & I’m all set for my top-off. |
