Used this for my jet pump as it was leaking on the suction line and cycling my jet pump often.. once installed it failed immediately.. I think it could work for certain tasks but didn't hold up for this job unfortunately

Used this on a shallow well with a hand pump. First had at top of pipe near pump and it worked for alittle while after priming the pump, came out a hour later and it leaked down cause me to have to prime pump again which it the whole reason i purchased it. I then pulled it up and put the valve at the bottom of pipe about 18 feet down with same results. Took it apart lubed o rings and valve and still leaks down maybe I git a dud but when i get around to fixing it Im going for a metal ball type check valve cause this rubber type heart valve in a plastic tube isn't working for me.

Bought this for the bilge on my boat. Worked fine for a few weeks and then water started to slowly drain back through the valve. Now my bilge pump cycles every 5 minutes when it should not be cycling at all. After 5 years sure, I'd expect it to need replacing, but not after a month. Do yourself a favor and buy something else. All these 1-star reviews are saying the same thing.

I used this on my sailboat's automatic bilge pump discharge. The hose installed by the builder is 1". The newer bilge pumps use 1 1/8" fittings. I have a foot or so of 1 1/8" hose that curves upward coming out of the pump. I installed this valve vertically and it connects perfectly with the 1" hose that runs overboard. In my configuration I have about a gallon of water standing in the piping. The valve effectively prevents that water from draining back into the bilge.
