Learn what the six most common problems are and how they can be solved.
1) Small stones get caught in the check-valve body. All sump basins get small stones in them because the drainage pipe system running underground around the perimeter of the house is bedded in small pebbles. Cleaning the basis periodically to remove them helps; however sooner or later one of more will get caught in the check-valve body.
The flapper style (traditional) attached to the discharge pipe using hose clamps is most vulnerable. . Stones get caught in between the flappers.
The spring loaded gate style is least vulnerable. The gate is controlled by a spring which happens quickly and tightly preventing stones from getting caught. By the way, both check-valve body styles can be removed from the discharge piping and cleaned; however most people do not like the task of maintenance.
2) Water hammer or clunking sound occurs when the sump pump shuts off
A spring loaded gate check valve body uses a one-half pound spring which controls the closing of the gate. The gate controls the rate at which the water flows back on the gate. Read more
3) Attaching the check-valve to the discharge piping system can be challenging for those not adept or who do not like the task of measuring and cutting.
Until recently only the traditional flapper style bodies used the hose clamp method for attachment to the piping.
Now the spring gate loaded bodies also provide a hose clamp method for attachment. Read more
4) The hose clamp fasteners can fail by coming loose when you are not home and water sprays all over the sump pump basin area and can even result in basement flooding.
The spring loaded gate check valve connection types are numerous. Read more about each connection type and how they are installed.
5) Viewing the flapper is impossible to see if it is operating properly or if there is a problem. The check-valve must be removed in order to see if the hinge is bad or small pebbles are caught.
Clear check valve bodies made from clear PVC plastic allows viewing of the gate when water is pumping through and returning after the sump pump stops.
6) Limitation of installation angle limits choices.
The best check valve is the Brady Campbell Model 0823-15c 1 and 1/2 inch diameter. Magic Plastics also makes the quiet check valve for Zoeller. The one recommended is Zoeller Model 30-0041. Other diameters are also available.
Small pebbles do not get lodged in the gate as easily because of the spring.
The spring loaded gate is controlled by a one-half pound spring which operates something like a screen door with the tension bar. The screen door opens easily, but when it closes the tension bar keeps it from slamming shut and making a loud noise. That is what the spring on the valve body does. It controls the closing of the gate and thus eliminates the thumping sound.
The initial installation of a union connector may be a challenge for those who do not like to measure and cut. See how a union connection is done.
Remember, once the union connection is in place, thereafter whenever the check-valve is replaced, the body is easily screwed out and a replacement is easily screwed back in.
A union connection is secure and will not come loose.
The body so action of the gate can be observed. If it flops around or closes in an abnormal movement, it needs replacement.
The angle of installation is very flexible: 45 degrees, horizontally or vertically.
A one-fourth horse power motor is strong enough to push the spring-gate open.
I believe this is the sump pump part I appreciate the most. We have battled with sump pump noise for many years. One of our friends told us the noise was our checkvalve and not the pump. What a surprise. I was thinking the wrong thing all of the time. So we tried this checkvalve he recemmended and it really makes a big difference. The sump pump is below our bedroom so sometimes we wake up at night because it sounded so loud. Now we do not hear it any more. We recommend this checkvalve to anyone. It does make things much quieter.
It took me a while to believe a check-valve could make a difference.But this fantastic product is slieint. Our old check-valve on the sump pump was so loud I could hear it on the other side of the house. I must say the Campbell valve, we got the 0823-15C, is silent.
This is extremely quiet. I will not settle for the big box store cheap check-valves any more. They do not last and they knock. You will not understand the differenc euntil you install it. We use this on my basement sump pump and it is awesome!
Amazon consumers rate the Quiet Check Valve by Brady, the 0823-15C 1.5 inches port diameter and the Zoeller 30-0041 1.5 inch port size - 4.9 stars out of 5.
