I love it. I love it I love it I ...
I love it. I love it I love it I love it. It's perfect. My new 19mm shower drain pump hose fitted nicely over this check valve it and secured snugly with a lovely shiny jubilee clip on each end. Deeply satisfying and a thing of functional beauty. And what's genius about this is that it lets the water flow out one way, and not back the other. And behold my boat shower tray empties in seconds. Bob is your uncle and fanny is your aunt.

Just the job
worked well - fitted an extra bilge pump to single hose. This NRV will prevent back filling

Expensive but works extremely well.
I used this non return valve to stop water from my upper pool draining back to a lower pool and it did an excellent job. It was easily inserted in my plumbing and only took a few minutes to install.

Didn’t work.
Not very effective when used on my washing machine outlet. Just rubber flaps inside inside it and allowed sink and dishwasher water to pass back into my washing machine. Now changed to a mechanical pressure activated valve which works a treat.

Very tight fit
It's very straight forward to use but you may want to use some boiling water to use on whatever pipe your using because it is a bit tight to squeeze on

Does not work
Used it on my reef aquarium as a safety measure in event of a power cut, does not work, sump and floor flooded :(

WHALE Rückschlagventil für 19mm-Schlauch funktioniert gut
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!!!

Bilge pump
This unit stops the constant cycles my bilge pump goes through lifting water 2.5 feet up and out

No es lo que esperaba.
La compré porque decía que era 3/4 a 1 pulgada y no es cierto. Quizá de 1/2 pulgada si es, pero no me sirve. Terminé comprando una igual pero de 3/4.

Highly recommended
So far so good. My garbage disposal was backing up food into my dishwasher for years and it was gross. I finally got around to installing this check valve which stopped it and I can’t believe I didn’t do this sooner. It was so simple. No leaks and works well
