Check fittings are attached correctly; confirm valve is hooked up the intended way.
About the Check Valve
- Purpose of the Check Valve: Allows flow to go in only one direction.
- How it works: Flow moving toward the ball (the catch), it'll catch. Flow moving away from the ball (around it), flow will continue.
- Because of this, it is critical that the check valve is hooked up correctly (in the intended direction).
- When it's used: When flow is needed only in one direction. Example: Pumps.
Common Component Failure Problems
- System is not working as expected.
- Is the valve hooked up correctly? Are there any leaks?
- Is the valve hooked up backwards?
- Are hoses hooked up to the correct ports and connected to the correct components?
- Are the hoses attached correctly?
- Is there any scarring or damage on the fittings?
- Check pressure.
- Is valve getting proper pressure?
- If not, problem is likely upstream.
- Check flow.
- Is the flow high enough for the valve to function properly?
- If not, problem is possibly upstream.
