Frequently Asked Questions
Can I get a seal kit for a Ryobi pressure washer pump?
Yes — pump rebuild/seal kits for many Ryobi pressure washer models are available from Ryobi dealers and online. Use your model number to find the correct kit.
How do I prevent Ryobi pump damage in winter?
After the last use of the season, disconnect the water supply and run the machine briefly to expel water from the pump. Store in a frost-free location.
Is the Ryobi pump repairable or should I replace the whole machine?
For Ryobi corded models, pump seal replacements are cost-effective. For the lower-end cordless models, full pump assemblies can sometimes cost more than a replacement machine — compare costs before repairing.
