I have a drain with a 1/4in opening and hose attached it is at a 90 degree angle. My problem is the drain will not work if water enters the channel very quickly and covers the hole completely. I have noticed that there will be a pool of water in front of the drain sometimes and will not drain then it overflows.
I tested the drain and when water enters the channel to drain it works fine and even creates a siphon if there is a lot of water constantly draining. My problem is if water quickly covers the opening it will somehow not drain. I assume this has a fancy term in the hydraulic world but I need to know how to fix it. The drain hose/line is clear and drains perfectly when water enters slowly. Even if I pour water in and it covers the drain, but only after it has started to flow. If I cover the drain very quickly with water it seals with air pressure or something..
Any ideas of what this phenomenon is called or how to fix it? I was thinking of putting a pin hole in the top of the drain line at the entry.
Thanks in advance
