How to set level in sump

[Saaqib_Ansari]

Hi sorry for all the posts recently I just don’t want to make any mistakes spent a lot of time and effort want it to be perfect.

So I just wanted to know how do I set the level of water in the sump? Do I fill the main tank to where I want it, then the sump to where I want it then open all the valves and return pump?

Water in the display is set by the height of the overflow.

As for the sump, if you’re using baffles or dividers between sections, the the only section you’ll see any fluctuations in is the return area. Water height in the other sections are set by the height of baffle walls.

Water height in the return area will fluctuate as water evaporates and fresh water is added to make up for this. Set the sensors for your ATO to the desired height you wish to maintain in the return section of your sump.

Also, make sure you set the level low enough so that if you have a power outage, you leave enough room for your display to level out and not overflow the sump. To test this, turn off your recirculating pump and see where things settle and verify that your sump doesn’t overflow.

You just want to plan for every situation.

Also, depending on your return setup (like if it terminates lower than your overflow) I would make sure you have a way to prevent back-siphoning.

What does this even mean
If water siphons back through the return pipe what would happen

Most definitely simulate a power outage. while the system is running mark on the sump the level with a marker. Then simulate a power outage and see if the sump over flows it is okay if it fills all the way up just as long as it doesn't over flow. Now the level is set and you can set your Auto top off to that mark. If the sump looks like it will overflow turn the system on to prevent it. Remove some water and find the level that will allow it to run and have a power loss situation not overflow the sump.

When your main pump stops, if your return is under water, water is going to back-siphon into your sump until the siphon is broken.
