Great idea! I may implement this myself. Here is a picture of what I did. I added a little tiny piece of the same silicon tubing on the exit side in order to make them fit nicely in the holes I drilled. When you get them you can test out what way the flow is by blowing into it. Air will only pass o...

You need to make sure the lines are totally sealed where they attach to the pumps. I used small zip ties and tightened it as hard as I could, using pliers, then I even siliconed over some that were still losing suction. If you seal these joints, they will not leak. Thanks for the advice I purchased...

Are the pumps physically physically located above the tank? Sounds like gravity is happening. Yes, I have a shelf system that mimics how ledgardner had his in the video. The top shelf is the controller and nutrients, the next shelf below that is the ro tank, and below that is the nutrient tank. Inc...

I have been experiencing a problem with my dosing pumps. The exit lines from the pump to the nutrient tank over time leak into the tank. This is noticeable from home assistant charting a gradual uptake in ec as well as the line visually building air pockets next to the pump. I have included pictures...
