Common Questions
- Can I install it vertically?
- Yes. The IN 1/2 is rated for horizontal or vertical lines because the spring, not gravity, closes the disc. In a vertical run the flow must be upward through the valve, following the body arrow.
- Will it slam or cause water hammer?
- No. The spring closes the disc before the flow actually reverses, so the valve seats silently instead of being slammed shut by the returning column of water. That is the point of a silent (non-slam) check.
- Does it come with a strainer?
- No. This is an inline check valve only. If the line carries debris, install a strainer upstream — grit on the seat is the usual cause of a check valve weeping by.
- Is it potable rated?
- No. This model is not certified lead-free, so it is not for potable-water piping. Watts LF-prefixed check valves cover potable applications.
