For a vertical riser, use a spring-loaded silent check instead.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWill it slam or cause water hammer?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt 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.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes it come with a strainer?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo. This is an inline check valve only.
