I am trying to create a pump that will refill a storage tank with the following conditions:

1. The pump will activate when the connected storage tank becomes less than 15k full.
2. The pump will continue to run and will stop once the connected storage tank is at least 24k full.
3. The pump will not activate again until the connected storage tank falls below 15k again.

I have been tinkering with the combinators for a while not but I have been unable to get these conditions to work.
Does anyone have any ideas?

What you want is called hysteresis.
Here's a topic showing how to make one easily : viewtopic.php?f=193&t=32432
you can then output that to a small pump that will do the job

My apologies, I looked through the post you gave me however I am having difficulty understanding how to implement it to a pump and storage tank.
What should the storage tank be connected to and what should the pump be connected to?

Additionally, what would i set the constant as? Or how would I set any of the combinator settings for that matter? The instructions in that post seem a bit lacking for describing how to implement the system to different applications, unless I am just not reading it right.

Through trial and error i have figured it out. I thank you for your assistance.

Sorry, the fact is I knew what you were looking for was there, but I'm too much a noob in combinators to understand what was needed

It's no problem at all, I finally figured it out and it works perfectly... I just needed to figure out where the pump and storage tank needed to be connected at. It appears my impression on the calculations was correct in any case. Thank you for your help.
