Check valve question

[saltwaterwannabe]

Does anyone use flap style check valves with a supplemental spring in their system? I have one but am a little concerned about the metal spring corroding. I bought this as a replacement for a sanitary check valve on my sewer pump at my old house but never used it. Any thoughts?

The Georg Fischer Wye check valve is the only one I’ve ever used. I had one on a bottom drilled 150 gallon FOWLR tank I used to have.

I don’t like using check valves, but if I had to do it again, that’s the only one I would buy!

The design makes it easy for you to remove the check valve mechanism for cleaning, which I did monthly. I agree with BRS (below), in that you get what you pay for.

Fwiw,
A ball valve in line with the check valve may also be a good idea, to isolate the check valve while cleaning.

I use the Georg Fischer Wye check valve on two tanks and have had no problems out of them

Check valves allow one directional water flow and are used to prevent back flow and siphoning. These are among the highest quality check valves to be found. Relative to other types and manufacturers of check valves, these valves create minimal pressure loss. They are commonly used on return pump...

The one linked above worked for us and while not as easy to clean as the Y style, you could replace them for not that much money. Just unscrew it and screw in the new one.

Thanks for the response folks, y’all are great!

I was trying to fully setup my plumbing before moving my sump. I will just reuse the true union one from BRS that is on my current plumbing.
