Superior Pump 99555 Universal Check Valve, Plastic, Fits all 1-1/4-Inch or 1-1/2-Inch MIP or FIP, Black (Pack of 1)

I have a water feature (a Home Depot Serenity Bowl) that holds a lot off its water well above the catch basin, and quickly back drains (and floods), when I have to shut off the power to the recirculating pump. But with this device in place, it greatly slows down the process,and avoids the flooding.It's a little big for the limited space that I have in the catch basin, and I am using 3/4 inch flexible pipe, but with a few adapters and a pair of elbows, it works great all season long.So I got a second one to use in another water feature with the same issue.

Used this for my new sump pump set up. So far has been working just fine, in a vertical pipe.

Ok

I bought two of these checkvalves. They both work perfectly. I would recommend this.

Purchased it but did not need it any more but i is stronger than i taught good quality.

It works as a one way valve but when on an upright pipe it leaked a little at the threads even with tread tape and plumbers putty.

I purchased this check valve with a Superior Pump 91250 1/4 HP Thermoplastic Submersible Utility Pump. I installed the valve, along with the 1.25 inch adapter, on the pump and put the garden hose adapter on the output side of the valve. I hooked up a 50 foot 5/8 inch garden hose and lowered the whole assembly into the water. I turned on the pump, and it worked fine.But when I turned on the pump a few days later, it wasn't discharging any water. I pulled it the assembly out of the water and removed the discharge hose and check valve. I couldn't find any problems (the valve seemed to be working as designed), so I hooked it back up and put it in a bucket of water to test it - when I turned the pump on, it shot a stream of water in the air, so I hooked everything back up and put it back in the standing water. When I turned on the pump, it again worked fine.A few days after that, I turned on the pump, and again no water was being discharged. I took the valve and adapters apart again, and this time I used Teflon tape on the threads before screwing it back together. Then as I was tightening the fittings, I heard a "pop" or cracking sound, and I thought I had cracked the valve body or an adapter fitting. But When I put the pump back in the water and turned it on, it pumped fine without any visible leaks. So I guess I was lucky.I have used the pump a few more times, and it now seems to work every time. Apparently, you need to seal the threads to assure everything works reliably - I would understand this being an issue if the fittings were on the input side of the pump (to prevent it from sucking air and losing its prime), but I'm not sure why a "perfect" seal was required on the output side. In any case, I thought I'd pass along my experience in case anyone else ran into similar problems.Overall, I'm happy with this check valve and will probably purchase it again if I need another utility/sump pump.11/23/2013 Update:I purchased another one of these check valves along with another sump pump (Superior Pump 92372 1/3 HP Thermoplastic Sump Pump with Vertical Float Switch) a few months ago and put them into service - I have used this pump/valve combination with both a small (5/8") garden hose and a large (1-1/2") hose for the discharge. The inclusion of the two 1-1/4" to 1-1/2" pipe thread adapters makes adapting the valve to various inlet and outlet sizes simple. The 2nd check valve (and the sump pump) have performed flawlessly to this point; therefore, I am very pleased with both of these check valves, and I am revising my overall rating from 4 to 5 stars.

This is exactly what we needed !

works just fine as a check valve.

funciona adecuadamente para bombas sumergibles

It appears to work very well - hope it continues

Se ve que es de buen material, lamentablemente la publicación no especifica bien las medidas y no me sirvió es demasiado grande para lo que la ocupaba, pero la voy a concervar para si en un futuro la llego a necesitar mide de largo 18cm y de ancho de rosca 3.5cm espero y les sea de ayuda mi comentario

I liked the multiple options to attach this valve to your pump. The review gets 4 stars instead of 5 because the flow direction marking should be larger and more visible to prevent improperly installation and possible pump failure.
