Review: Das WHALE Rückschlagventil, an dem Schlauch unmittelbar nach der Bilgenpumpe montiert, tut letztlich das was es soll, nämlich dass die Wassermenge, die von der Bilgenpumpe abgepumpt wird und die es nicht ganz bis zum Bordauslass schafft, nicht wieder zurück in die Bilge läuft, einfach super!!!

## Questions & Answers

**Q: will this valve fit a 3/4" ID vinyl hose?**
A: Yes. But it did not work and I lost about 75 gallons out of my saltwater tank when the power went out. Only took about 3 min. For half of my tank to empty.. I would find a nicer piece if i were looking.

**Q: How does this fit both 1" & 3/4" pipe?  From the pictures I don't see any way to support multiple diameters.**
A: The smooth is 3/4 the ridged is 1 inch.

**Q: Will this work to keep water from draining back into my washing machine?**
A: I will say it does. I use it to keep water from draining in my dishwasher machine

**Q: Can this be used with a dishwasher drain hose, to prevent backflow from the garbage disposal?**
A: Provide an easy way to maintain prime in a suction or discharge line. Suitable for use with manual or electric pumps

### ⭐⭐⭐⭐⭐ Review
*by S***E on 17 April 2025*

As many others have said, this works perfectly to prevent backflow into a dish washer. The item can be cut to accommodate various hose sizes. My advice would be to carefully check and re-check sizing before cutting the part. Ask me how I know..... I was able to recover, but cutting a bit too much off cost me some time and effort. No fault of the part - all on me. Good luck!
