**Q: Will this work to maintain the prime of a kitchen soap dispenser? (I had to use long 3/8 tube, down to container sitting on shelf)**

We do not recommend the use of our check valves with kitchen soap as the soap will be too viscous.  If you have additional questions please feel free to contact our technical support department at 877-700-4242.
