This worked perfectly for me!

One thing, is if you fill with too low of a flow of water, the siphon will never open up and drain. We thought we could just use a really low flow to save on electricity, and only try and fill it about once an hour. We ended up buying an on / off adjustable interval timer with a much higher flow that fills the tank in 4 minutes, where the old pump took about an hour to fill. So, the interval timer is set to 4 1/2 minutes on, 60 minutes off. - Then, everything worked great, and probably a much better solution in the end, as i believe that slow pump would have probably clogged...The seller was helpful and customized our unit for our height needs and sent out documentation that helped with setup. Kudos, and much appreciated in this robot customer service era!

This has never failed to operate.
