SUMMARY

The discussion centers on the mechanics of soap dispensers, specifically addressing a malfunction where soap dispenses when the pump end is blocked. It is concluded that certain valve types in soap dispensers require back pressure to function correctly. When the pump is obstructed, the pressure changes, allowing soap to flow. Understanding this principle is crucial for diagnosing similar issues in soap dispensing mechanisms.

PREREQUISITES
  • Basic understanding of fluid dynamics
  • Familiarity with pressure and vacuum concepts
  • Knowledge of mechanical valve operation
  • Experience with troubleshooting household appliances
NEXT STEPS
  • Research the mechanics of different types of valves used in dispensers
  • Study fluid dynamics principles related to pressure and flow
  • Explore troubleshooting techniques for common household appliances
  • Learn about the design and function of soap dispensing mechanisms
USEFUL FOR

Homeowners, appliance repair technicians, and anyone interested in the mechanical workings of soap dispensers and fluid systems.

Homework Statement


My soap dispenser does not work, but when i block the pump end the soap comes out, can someone explain to me why?


Homework Equations


I am looking for a relevant equation to prove why it doesn't work
