It’s bloody annoying when your sprayer let’s you down, and it’s often right when you need it!!
So follow this handy ‘self-help’ guide to diagnose the problem with your pump and avoid calling in the experts (that would be us!).
To fix your spray pump, ask yourself the following questions:
Is the pump suction filter working properly?
- Is the suction filter blocked?
- Is the suction filter sealing correctly? (check the o-ring)
Is the pump suction line in good condition?
- Is the PVC suction line cracked or hard?
- Note: Even a suction line that will hold water can still to suck air which is no good!
Are the pump fittings in good condition?
- Check the joins/connection points to ensure all fittings are sealing correctly
Are the pump valves operating fully?
- Each valve seals the unit which stopps pressure loss – is there grass or a stone stopping it from sealing?
- Is there an oil or water/chemical leak around the pump itself?
- If the pump oil is white then it’s likely the chemical has mixed with oil – not ideal!
Are the pump diaphragms in excellent condition?
- Diaphragm’s can have a hard life, so check for any holes or foreign objects
- Each diaphragm needs to be in great condition (eg, not perished)
If your pump passes the checks above, check the pressure control (regulator)
- Check that the manual valve operates fully
- Check that the main (bypass) valve opens and shuts fully
