FAQ
Q1: Where are the check valves located on a TU26 sprayer?
A: TU26 sprayer pumps typically have two check valves: one on the inlet (suction) side and one on the outlet (discharge) side. Both may need replacement if pressure issues occur.
Q2: How do I know if my TU26 check valve has failed?
A: Symptoms include loss of spray pressure, the pump running but not priming (no fluid output), fluid leaking back into the tank, or inconsistent spray pattern with sputtering.
Q3: Should I replace both check valves at the same time?
A: Yes. If one valve has failed due to wear, chemical damage, or debris, the other is likely in similar condition. Replacing both ensures balanced performance and saves future repair time.
