Are these correct for Intermatic model T104P3?
Hi, Jay. These Trippers - 156T1978A can be used with the Intermatic T104P3 unit.
Is there an advantage to run the pump for two shorter sessions instead of one longer session? Also, Is it possible to get two on trippers instead (we have two off).
Hi, J. There are no advantages to running the pool pump for two shorter intervals.
Would these trippers work on Model T110
Hi, Jane. These trippers are compatible with the T100 series timers. The T110 falls under that so these trippers will work with the T110 timer.

Pros: works great
Cons: little pricey
I had tried other timers but they just would not work. I was having to go home from work everyday to turn my pump on. It was really becoming difficult. I was so glad to find your website and the shipping was awesome! I would definetly recommend your site.
