Actually it's the other way around,
I have the through holes that I get in the electrical department on both ends of the tube, but they don't limit anything (except the size of the hole). The one that has the white P.V.C. tubing that runs up and down and directly into the reservoir is the overflow. I simply stuck a piece of clear 5/8 inch vinyl tubing in the P.V.C. "T" and then stuck it onto the through hole. The key is the placement of the hole in the end cap, so the water level does not rise above where the hole is located. I tested the system and marked it before I glued the end caps in in place. This system is a flood and drain type system. When the
pump shuts off the
nutrient solution simply drains back into the reservoir through the inlet.
The one on the other side that runs horizontal is the water inlet. Again the through hole does not limit anything it just lets the water pass through it and provides a watertight seal. The pump itself has an adjustment that is set at low because it's a powerful pump. The corner is made using just a few small pieces of different sized vinyl tubing and a couple of P.V.C. connectors to connect the vinyl tubing to the P.V.C.. The black is just paint that covers regular 1/2 in P.V.C. tubing to light proof it. I could have just used a long piece of vinyl tubing instead of the 1/2 inch P.V.C. tubing, but it's cheaper and I already had it anyway.
