I am sure some of you know but this photo is the same concept simplified into a single pipe. (I modified your photo Rallysman) The height of the T will determine the water level height in the tank just like the first photo. I use 40mm PVC pipe for high flow rates which lies flat against the tank unlike this image.rallysman;1248187; said:
those would work the same, but the DIY overflow sticky posted here seems to get air into the system because it's skimming the surface. That's what I've experienced anyway. When a fish splashes like mad when feeding, the DIY in the sticky seems to get air in it.fishdance;1384430; said:I am sure some of you know but this photo is the same concept simplified into a single pipe.

im kinda confused by this, it looks like a piece of PVC pipe shaped like a U. i don't really understand where the T comes into place. I had planned on putting a 90º elbow on the inlet of my overflow with a filter sponge on it, to help eliminate the amount of air that gets into the overflow, also i planned on putting a aqualifter pump or hooking a line to a venturi to help make sure it wont lose prime. Rallysman can you please post pictures of yoursrallysman;1398093; said:
Mike in the DIY articles stick EH has a huge write up about the PVC overflow this is great for a DIY autochanger as it flows slower but the other writeup has alot more info for a Regular the ideas are the same just the tee has to go lower.mike dunagan;1547357; said:
