Why is the safety valve leaking air on my Probuilder Paint Sprayer?
- DDeborah RodriguezAug 4, 2025
The safety valve on your Probuilder Paint Sprayer might be leaking air because the pressure in the tank is too high. Reduce the tank pressure to 20-50 PSI. Alternatively, the safety valve itself may be defective, in which case you should replace it immediately.
