Jackel The Original Radon/Sump Dome (Model: SMR114-V) (1)

Great sump dome cover! Glad I ordered it since I was initially on the fence. It is very well constructed in terms of material, so now I understand why it is priced the way it is. My sump pit was originally covered with a piece of wood that was sealed with silicon caulk, so I had no access to check on the pump. My pump ended up going out and I had a little bit of flooding in my basement. Luckily was able to catch it before spreading too far and decided I needed a way to access and test the pumps as well as maintain radon venting. This dome was the solution. My pit was not standard, a little over 16 inches in diameter, but this cover fit well over it. I was able to get a 1-1/2 inch pipe through the pre-cut hold for the sump pumps to drain out and a 3 inch screw on fitting for the radon pipe. There is a provided rubber sealing piece for the sump drain pipe, but I was not able to get it to fit in the hole with the pipe. Maybe you have to drill a slightly larger hole, but I just used some clear silicon caulk to seal it. I had to use some elbows on the radon pipe since the dome was a little taller than where my existing radon pipe was. I didn't want to drill into the sides of the dome since I feel like it would be easier to service or take apart from the lid cover. I then used a hole saw to drill a 2 inch hole for the rubber wire insert that is provided. Since I put in 2 pumps, I had to drill two holes in to the insert, but was easy enough to do. I still need to screw into my floor, but for now sealed all around with silicon. One Con: The plugs for the screw threads that the bolts go into can fall out. I did have one fall out when I was putting the access side of the cover on, but luckily it didn't go into the pit. Be careful of this and maybe when I take the access cover off next time, I'll put some duct tape to hold the plugs in place a little better. I see the point of being able to swap them out, but they should secure better so you don't lose them in the pit.

Product arrived very quickly and is exactly as described. Product is very sturdy, you can stand on it, and is very well made. Product installed easy and I have never drilled into concrete before. I have two sub-pumps in my finished basement and this one definitely took away the smell of the sub pump basin. I believe this will also eliminate any radon coming up from the basin however i will not know that until the tests are back, and I have just ordered the Safety Siren radon-detector that is highly rated on Amazon. I will order a second one of these for my other sub pump later this year. Highly recommended.

Bought this to cut down on my radon level. I had already bought a digital radon device and my radon level in my basement was running around 16. Following the instructions pretty carefully, after installation, my radon level is down to less than six. This is an excellent product! Very sturdy, and gives me peace of mind.

I wanted my 1-1/2 sump pump discharge PVC pipe to exit from the top. The existing two holes are a 3 inch threaded hole, which I plan to use for a radon vent pipe, and an unthreaded 2 inch hole. The rubber gasket that fits that hole is too small for a 1-1/2 PVC pipe - I needed a 2-1/4 inch hole, and enlarging a 2 inch hole to 2-1/4 inch is not easy. A hole saw needs a small hole for the pilot bit, so I had to place a scrap piece of wood inside the 2 inch hole so the pilot bit had something to drill into. But it worked out nicely. I then had to drill a 2 inch hole on the side, so I could bring the electrical connections from the side. Lots of work to get the setup the way I wanted, had to buy a 2-1/4 hole saw (I had a 2 inch one), but fortunately the design of this radon cover allows customization.

Very well engineered. At first glance you may wonder why you're spending $100 on a sump pump cover, but this thing is well designed and thought through. I'm using this as part of a radon mitigation system. There is no skimping on fittings and various pipe seals/flanges. They even included a drilling template for the sump pump discharge pipe . Typical design is to have the discharge pipe come in from the side and the radon vent from the top. Cords come in from the top (even though mine enter from the side. Snugs up to the floor for air tight seal. I didn't understand how a 3" PVC pipe was going to work from the description but you'll need a 3" PVC threaded adapter from Big Blue or Big Orange. The black ring is included with the dome cover and has a seal on the back side. Sure you can spend $30 for a piece of Plexiglas and silicon chalk but after installing this and seeing the quality of the work, why go there. Jackel gets an A+ here. See photos.
