An improvement to a corner-box drywall taping tool. It uses a housing similar to the existing tools. This housing has a quick release spring-loaded one-way valve attached to the mud area of the tool. One a roll of tape is installed; the unit is attached to a mud pump by the quick release fitting. A pump then fills the housing with mud in about 20 seconds. To prevent the case from opening under the pressure of the pump, additional latches are required to seal the housing. When the mud is exhausted with this device, the operator returns to the mud pump, attaches the fitting to the pump and in another 20 seconds is ready to go. This process can be repeated until the tape supply is exhausted. In this way, the device saves a lot of time during the filling process.
