Campbell Quiet Sump Pump Check Valve

The Campbell quiet check valve is rated so highly, a 5 star, because it is quiet. The swing gate and its hydrodynamically design cause water hammer to be greatly reduced. Consumers are shocked that they cannot heard the thud of the water against the valve gate when the pump shuts off.

The great reduction of water hammer is due to the fact that the check valve is designed to fit snuggly so no air or water can seep through the sides of the gate which flops shut (down) when the pump shuts off and the water pressure subsides. The less air and water that seeps around the gates edges, the less water hammer there is.

When reviewing over 200 consumer reviews, the first thing that is consistently mentioned by those that purchase it is that they have found the Campbell to be the quietest check valve available to homeowenrs.

A quiet check valve really makes a difference. In addition to being ranked 5 out of 5 starts is that it is also as a best seller.

Dale, a consumer from Iowa asks: Why is there such a loud sound when my sump pump shuts off? It is a loud clunking thudding sound. The sump pit is below our dining room and we have a bedroom in our finished basement. How can we get rid of the irritating noise? I thought the noise was the pump. I called the manufacturer and he said the sump pump is not making the noise; it is the check valve that is making the loud clunking thudding sound.

The loud sound Dale heard caused him to ask: Is there such a thing as a Quiet Check Valve For The Sump Pump?

The following information is provided to help you understand how the loud noise happens, how the design makes a difference in the noise level, where you can find the quiet check valves, how to install them, and what other customers say about the quiet check valves for sump pumps.

The force of water flowing backward through the discharge pipe when the sump pump shuts off causes a loud clunking thudding noise as the water hits the check valve. Eliminating the check valve is not the solution.

A check valve is placed in line with the PVC discharge piping connected to the sump pump discharge port to prevent water remaining in the discharge pipe to flow back down the pipe through the pump and back into the pit when the pump motor turns off.

The check valve prevents the sump pump from pumping the same water over and over and prevents unnecessary wear and tear on the pump.

The sump pump motor and impeller give velocity to the water as it moves upward. The check valve gate opens upward as the water comes through. The profile of the gate makes a difference in how the liquid flows through.

The more specifically the gate is designed to give passage to the water and air without causing a change in its velocity, the smaller the amount of pressure loss. The lower the pressure loss, the quicker the gate moves back into closed position preventing air and water from going through the sides of the gate and causing water hammer.

The more precise the fitting of the gate to the wall of the inner chamber the better the seal and the lower the chances of water hammer.

By applying the explanation provided above, it becomes obvious there is a distinct difference between the hydrodynamic design of the Brady or Campbell check valve and the common hardware stocked check valves.

In addition, when putting ones finger inside the inner chamber and feeling the movement of the gate, it becomes obvious that the spring gate of the Campbell check valve will close rapidly.

The Campbell check valve is most quiet. It has a highly defined hydrodynamic design and a ½ pound stainless steel spring for the spring gate.

The Brady is as quiet as the Campbell check valve. It has a highly defined hydrodynamic design; however the flap gate is hinged and does not have the strong steel spring. Customer reviews indicate the Brady check valve is as quiet as the Campbell.

The Basement Watchdog comes in third. It has an additional air chamber to absorb the noise.

Zoeller, Little Giant, Flotec and Wayne rank fourth. Some of them are designed with an inner chamber with some hydrodynamic design and a looser fitting flap. They work fine if you don't mind a noise every time the sump pump shuts off and a small amount of water running through the check valve and back through the pump and into the sump pit.

Quiet sump pump check valves are slightly more expensive than other sump pump check valves.

The Campbell and Brady check valves were very comparable in price at the time of this comparison. Campbell was $16.56 and Brady $17.55. The Basement Watchdog Klunkless was most expensive at $24.99.  Wayne was cheapest at $9.61. Zoeller and Little Giant check valves were the same price $11.25. Flotec was $13.25.

Based on price comparison, the Campbell and Brady  check valves are the best choice - their price is competitive and they are rated by consumers as the quietest check valves.

My plumber put in a new sump pump. The new sump worked fine, but I began to notice after it finished its cycle there were two loud "clunks". I began to investigate and found the noise was due to the check valve closing and the pressure in there was making a "water hammer" clunk. I mentioned this to the plumber. He told me he put in a good quality check valve, but I could tell he did not seem to know as much on this topic. So I did more research and found the Brady valve online, purchased it and asked him to install it for me. He seemed a little skeptical, but said he'd try it. There is barely a sound when the check valve shuts off now. I am so glad I found this.

Total silence. This has changed my life. To think I listened to the clunking thudding sound for over 20 years. Its so quiet I have to remember to check the sump pump system to make sure it is working. I don%u2019t hear a sound. I really think it is cool to see the gate work through the clear plastic. I love my Campbell check valve.

I have a one horsepower pump. I was having trouble with all other manufacturer check valves either blowing apart (rubber type) or failing prematurely. I was wondering if I would ever find a good check valve. I found the Campbell. It works with my one horse power pump. I can see the internals to see if everything is working properly. There is no noise either. If you want a reliable quiet check valve look no further. I have bought 3 of these, one for each pump in my house, and will never turn back to any other type.

The Pasco check valve has changed my life. Everything is so quiet in the house now. We live in a high water table so our pump runs every 15 minutes during dry days. I got so used to hearing the clunk of the check valve I have to remind myself to check if the sump pump is actually working now. I can't hear it upstairs any more. This is a great invention.

For years I listened to the water hammer sound when our sump pump went off. I installed a Pasco check valve 23 inches above the pump, and it solved my problem completely. No sound at all now! I have a 1 1/4 PVC so bought adapters to transitiion to the size of my 1 1/4 PVC since the Pasco check valve ends are 1 1/2 inches. It was not that expensive either.

Our sump pump made such a noise when it shut off. I thought it was the pump. In talking to a plumber I learned it was the check valve. I asked him what he would recommend. He suggested the Campbell quiet valve. I found one at Amazon for a great price. I installed it myself. Not really hard to do. Now it is so quiet when the pump runs. This is a great product.

Listen for yourself. Can you hear the difference between a standard and quiet check valve? The following video clearly demonstates the difference in noise level.

Quiet check valves are easy to install. Here are the steps.

1. 1) Hold the new quiet check valve next to the existing valve. Note the difference in length. Quite check valves are around nine inches in length. If the new valve is longer, then the PVC discharge pipe will need to be shortened. If the new valve is shorter, an additional length of PVC discharge pipe will need to be added.
2. 2) Before turning the pump off by unplugging it, remove as much water from the sump pit as possible.
3. 3) Remove the old check valve expecting the remaining water in the discharge pipe to shower out when the old valve is disconnected.
4. 4) Determine if the distance between the two ends of the discharge pipe where the check valve is installed is sufficient. To shorten, mark where the discharge pipe should be cut and use a hack saw to shorten it. To lengthen, add an additional piece of discharge pipe attaching the extra piece by either using a rubber union and stainless steel clamp or gluing a PVC coupler to attach it to the existing PVC pipe. We added an additional coupler.
5. 5) Make sure the new check valve is in the 'up' position.
6. 6) Glue (prime first then glue) the quiet check valve coupler to the PVC discharge pipe. Wait for glue to dry according to manufacturer specifications.
7. 7) Plug the sump pump into the electic outlet.
8. 8) Listen how quiet the check valve is.
