The pump tube is the workhorse of the pump and requires scheduled replacement according to the needs of each individual application. The first time the pump tube is replaced is a fair indication of the approximate life of the tube in that particular application.
Be sure to verify that the tube replacement was due to wear and not an outside contributing factor that could shorten the tube's life.
Check for:
Chemical attack
Mineral deposits at the injection point
Sediment blockage at the check valve
Seized rollers
Exposure to extended heat or sun
Excessive back pressure
Each pump manual includes a troubleshooting guide.
