Hi, all,

My basement system was tested working the first day and then after I put all the rocks in, for some unknown reason, the snorkel stops working so it just keeps siphoning!! Anybody has any idea to help? I checked everything I know such as snorkel tube length, outlet length, height of bell siphon, etc. It siphons beautifully but it just won't stop. The snorkel tube is making a lot of noises right now but just can't stop. All the measurements are correct and it worked when it had water only....very puzzling. Thanks.
