Common Questions
- Can I install it vertically?
- No. The LFWCV 1 is a swing check — the disc closes under its own weight, so it needs a horizontal run with the bonnet up. For a vertical riser, use a spring-loaded silent check instead.
- Will it slam or cause water hammer?
- It can. A swing check closes on the reverse flow itself, so on a pump discharge or any line with fast stops it may slam. Where that matters, choose a spring-loaded silent check or a dual-disc wafer 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?
- Yes. The LFWCV 1 is certified lead-free for potable-water piping.
