3/4 inch Check Valve, Marine Boat Bilge Pump Hose in-line one way, Non Return

It worked perfectly for 2 years and then it just stopped. The rubber flapper now gets stuck immediately after taking it apart and blowing through it. Otherwise it's been a great check valve and worked perfectly for my bilge in Salt water. Maybe would last longer in less harsh conditions. I'm going to try the whale brand valve and see how it does. Time will tell.

no problems with the check valve

Yo lo uso par que la water pump saque again fires de mi boat y la Del Mar no retorne es buenos buenisima ya lleva tiempo conmigo y functions perfect

Unit has limited flow restriction however if you order the 2 pack it only comes with 2 hose clamps. You will need to purchase 2 additional clamps to have 2 functional check valves.

Used this check valve to prevent my gas furnace condensation drain from backing up into the fire chamber.

Item as described

Works great as a backflow inhibitor to a dishwasher

All good all works

Not sure if it was supposed to, but it came with 2 valves but only the two clamps (as advertised). I used it on my boats shower/sink bilge drain hose and it does not back up at all, so it works. We'll see how long it lasts.

Fits and works perfectly

Exactement ce que je cherchait. correspond a la pression de la pompe de cale que j'utilise.

Fonctionne tres bien sans perte de débit de la pompe de cale, le clapet est étanche, Bon produit!

J'ai réglé le problème de retour d'eau continuel lors du pompage de l'eau d'un puits souterrain.
