My previous boat had a backflow preventer between the pump and the water heater input. My current boat doesn't.
I am re-doing some plumbing on the new one, de-Rube-Goldberg-izing it, I think is the term, and noticed no backflow preventer. While ordering some additional Parker "O" Ring/Grab Ring Tube Fittings (which I really like, by the way), I ordered a check valve that I plan on installing before the water heater.

I was just wondering, is this the correct way to do this? Is a check valve recommended, necessary?
Thanks.
By the way, the Parker fittings are really great. The current boat has polybutylene tubing, which is a problem in houses, apparently, but no issue in boats. It's unavailable now, so I purchased some LLDPE tubing, "linear low density polyethylene," which is food grade, good for drinking water, etc. $18/100'. It is available in colors, and cuts very easily with a tubing cutter tool, as what is used for PEX. The Parker fittings go together without tools very quickly, and hand tight is water tight, no tool needed or recommended to make them up. Highly recommended. I hate the nylon-reinforced vinyl tubing in the old boat, as it can kink, and it hardens with age, making it very tough to undo, remove from a hose barb, etc. This LLDPE and Parker is a huge upgrade for folks who do their own maintenance and upgrade work.
