Problem with siphon

  1. Jan 7, 2009 #1
    question -- When I go on vacation I set up a watering system for my plants.
    I set up a siphon by placing one end of a 30 foot hose in my toilet tank and
    the other in a bucket with a submersible pump and timer. It works very well
    BUT every day the level in the bucket is reduced slightly. After a week the
    bucket is only half full.
    The syphon is obviously working but not completely. The only thing I can
    theorize is that there is a pinhole in the hose that allows some air to
    enter. Or maybe dissolved air accumulates in the hose between cycles
    .HOWEVER, how can the syphon work at all then?
    Note: the hose exits the tank and then runs along the floor and then up and
    over and into the bucket.
    Thanks for your help

    Did you check the timer? Maybe the water is leaving the bucket faster than it is coming in.

    That is not a problem. The timer is only on for a few minutes and then the bucket(never empty) re-fills from the siphon action - only a little less each day
