Common Questions

Can I install it vertically?

Yes. The SS07F-BP-GPM 10 is rated for horizontal or vertical lines. In a vertical run the flow must be upward through the valve, following the body arrow.

Will it slam or cause water hammer?

Possibly. This is a clapper-style check, not a spring-loaded silent check, so it closes on the reverse flow and can slam on lines with abrupt stops.

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 — it is specified for fire protection service. Watts LF-prefixed check valves cover potable applications.
