If your Ridgid wet/dry vacuum is spitting water back out when you turn it off, there are a few potential reasons for this issue:
Air Leakage: The most common reason for water spitting out is air leakage in the vacuum system. When you turn off the vacuum, air can enter through small openings or cracks in the vacuum's seals, pushing the water back out.
Check Valve: Many wet/dry vacuums have a check valve that prevents water from flowing back out of the vacuum when it's turned off. If this valve is faulty or blocked, it may not be working properly, leading to water expulsion.
Filter Issues: If your vacuum has a filter, it may be clogged or damaged. A clogged filter can reduce airflow, causing back pressure that pushes water back out of the vacuum.
Incorrect Operation: It's also possible that the vacuum is not being used correctly, leading to water being sucked into the wrong compartment or container that is later expelled when the vacuum is turned off.
To fix this issue, you can try the following steps:
Check for air leaks: Inspect all the seals and connections in the vacuum system for any signs of damage or gaps. Ensure everything is tightly sealed to prevent air from entering the system.
Clean or replace the check valve: If your vacuum has a check valve, locate it and clean it thoroughly. If it's damaged, consider replacing it with a new one.
Clean or replace the filter: If your vacuum has a filter, remove it and clean it thoroughly according to the manufacturer's instructions. If it's damaged or too old, replace it with a new filter.
Ensure proper operation: Double-check that you are using the vacuum correctly and that water is being collected in the appropriate container, not in the exhaust or blower section.
If you have tried the above steps and the problem persists, it's best to contact Ridgid customer support or take the vacuum to an authorized service center for further inspection and repair. They will have the expertise to diagnose the issue and provide a more specific solution.
