WAYNE CDU800 1/2 HP Submersible Sump Pump – Cast Iron & Stainless Steel, Vertical Float Switch, 5,100 GPH, 3-Year Warranty

Very durable and easy to connect the PVC pipe to in the sump pit! Very quiet and the float seems to be of good quality!

This is my third Wayne 1/2 HP pump that I am using as a backup to my 12 year old pump that is still working great. My first one lasted 16 years before the bearings started to wear out. Pump runs for several days in the spring and fall. Other than that they set idle. Great dependable product.

Very quiet and heavy duty, you will need a one way check valve with installation

I have used this brand for years. My pumps barely shut off in a year. They last.

It is a bit loud, but I’m sure it has to do with the fact that my bed andbedframe are on the ground and the pump is directly below me. I had my boyfriend install it for me. He said it was extremely easy, he is very impressed with the pump. I spent the extra money hoping it would be quiet because my pump is in my basement directly under my bed. So I can hear it very well. All the other pumps I purchased were SOOOO unbelievably loud. It would wake my son up form his sleep. I couldn’t have that happening. So he said this was the quietest pump that there is out there. So I obviously dished out the extra money for it. It runs very well and efficiently. But it does still make noise. He said that it is very quiet but I am being picky and that it is going to make noise no matter what. But it is the quietest of all the pumps I used. It works very well also. I just wish it were a bit more quiet... I can hear it right through my pillow through my bed frame and my bed is on the ground because of how my bed frame is set up. It’s ground level. That doesn’t help with the noise. Hope this helps anyone’s decision about this pump. My bf knows his stuff! he’s great with that kind of stuff so if he loves it then I think anyone would love it!

Wayne makes the best sump pumps out there… They are definitely the most quiet

Solid pump. No complaints

I get a lot of water in my sump pit. I mean a LOT. I replace my sump pump every 2 years as cheap insurance, and I use a Basement Watchdog battery-powered backup as a fail-safe. I've had this pump for 18 months now. Last night it rained so hard and so long that this pump was only idle for 10 seconds between cycles. For hours. Water was draining into my sump pit so fast that if this pump had failed or if the power had gone out, my Basement Watchdog backup pump could not have pumped the water out fast enough to keep up by itself. (I have a gas generator nearby and a third pump (a smaller utility pump with a garden hose attachment) that I keep as an absolute last resort and fortunately haven't needed to use yet.) This kind of rain happens a couple times a year. And this pump dealt with it and never complained. I'm not going to say it wasn't a stressful night nonetheless, but you get my point. This pump has run for thousands and thousands of cycles over the past 18 months and it's handled all of it. The only thing I don't like is the style of float switch on this pump. I prefer tether switches because they're adjustable, so you can let the water level get higher and have the pump run longer. This would minimize the amount of back-flow that drains back into your pit every time the pump stops. There's no way to add a third-party tether switch either, because the built-in switch is hardwired into the unit's power circuit, rather than using a piggyback cord as I prefer. Oh well; for what this costs, I'm okay with it and I'm not going to take off a star for something I knew about when I bought the pump. Great deal for what this is.

I have used the tether float system for years , in a narrow pit . This pump offered a VERTICAL FLOAT SYTEM , protected by a Metal wire loop, which will rub FIRST on the pit wall , vs . the float . No brainer , go with the vertical , and DOUBLE BONUS , switch is tested over 500 K times , and the actual float is a replaceable part fitting ALL models of Wayne vertical switches . Must do’s : Elevate the pump with a brick , etc on pit bottom ( 1” -2” will work ) And after much collaboration, even Wayne saying No Need , drill a Weep Hole, 3” up from pump attachment on discharge pipe, below check valve . Yes , the WAYNE PUMP , prevents cavitation, in the pump itself, but not the discharge portion. A really good Pump and proudly assembled in the USA 🇺🇸.

Very powerful and effective pump. Will be replacing in a few years with the exact same one. Works flawlessly. Word of caution: the previous set up that came with the house we bought has flex pipe from the reservoir to the outlet. This pump blew through this type of hose in no time. You will need to go solid piping with rubber joints

I bought this pump to replace a Simer pump I installed in 1993. I felt it was time. The Wayne pump is easy to install and it worked beautifully when I tested it by filling my sump pit; very quiet. That may be the only time it gets used except for testing occasionally. I live in an area where my weeping tiles drain directly into the sewer system. If the sewer system backs up then the excess water will run into my sump pit. That situation is a rare occurrence but it can happen. The sump pump is basically standing guard in case that happens. It provides peace of mind.

Excellent so far and quiet!

Every couple of years I replace my sump pump to avoid any water issues. Decided to give this one a try and I am not disappointed. The pump is sturdy and easy to install. It concerned me at first since I couldn't hear it running. Checked on it a few times and it was functioning perfect. I will replace it with the same product at the end of the warranty in 3 years. I recommend this sump pump.
