Customer Reviews for Everbilt Radon Mitigation Basin Cover

We just finished our basement and noticed radon levels would jump to 4.8-5 with a working radon mitigation system. Our house is less than a year old, so there aren’t any cracks in the foundation or the floor (that we know of). I noticed that the flimsy plastic cover they put over the sump pit had a terrible smell and air coming through it. So I went out and got this, and let me tell you, it works wonders. The radon levels are averaging .9 - 1.5 for the last two weeks, and the smells are gone.

I installed this today and it took a LONG time but did indeed get everything connected. It took approx 8 hours because of all of the manual PVC cutting and adjusting I had to do. Overall great product.

I installed a radon mitigation fan and was still getting readings of about 5. The person that installed it said i needed to cover the sewage ejector pump so i purchased this cover. The install was easy and now my readings are about .03.

After doing a 3 month text last year that resulted in a score of 5.9, it was time to do something. First thing was to buy a meter, this was the second. The meter showed 6.0 when it was placed in the basement. The install of the cover was fairly easy for a do-it-yourselfer. 25 years of gunk in the pit was the worst part of the project. After that its just a matter of lining up the pump with the cover and piping. Drew a few lines on the floor replaced the cover drilled one hole into the floor placed a nail in it, then drilled another on the other side and pinned it. This way the cover doesn't move while I drilled the others. Next remove the cover clean off the dust, 2 tubes of caulk just inside the holes. Replace the pump run the lines threw the cover set the cover and screw it down. What amazed me was the amount of draft that comes through that pit. I just vented the pit outside as a passive system no fan. The meter I purchased does a daily weekly and a 6 month readout. Since the install the reading on the meter have fallen from 6.0 to 2.24 for the last 2 months. The daily reading have gone from 0.48 to 2.65.

Looks great, functions awesome! Definitely worth it

I've been a home builder for over 40 years and have never cared for the end result of our sump pump installations. Lately, we also have to be concerned about radon and the sump crock is most likely a big source of it. This lid is the answer. It provides a safe covering for the crock and it seals tightly to stop radon infiltration. It has a fitting for a 3 inch pipe to hook up to a radon mitigation system if needed and it comes with multiple fittings for several different size pipes for discharge and venting. It makes for a very professional looking installation. I particularly like the window in the lid to check on the pump. A great product.

After years of needing covers finally found these and for price worked great on my sump pits

Easy to install. I have used these at least 10 times before, as I do handyman work, and these are used for mitigating radon, or part of the system. A hammer drill, caulk and impact driver.. wish it came with Tapcon style fasteners.. other then that, it's set for many applications. Would recommend this product!!

The cover on my basement sewage pit has never been securely attached and sealed since I bought the house 5 years ago. It sat pretty snugly over the cast iron pit so it was never my highest priority as it seemed to keep all the odors out of the basement even though the bolts had been snapped off, probably due them rusting out then shearing when some maintenance was done to the pump. So when the ejector pump's float switch started sticking and I had to do battle in the pit anyway I went looking for a solution to the cover issue and found this product. As it luckily happened, the original cover was made by the same company, and despite being 25 years old all the pipes lined up exactly with the holes in the new cover. Sometimes you win one. Installation was relatively easy. The instructions are pretty much useless, having very little detail. But that being said, if you are a competent D.I.Y. type it's mostly just thinking it over and figuring it out. They supply a slew of different parts and adapters, so you can almost certainly McGuyver it up with the supplied goods. A few hints might be helpful for you if you're planning on installing one of these things. 1) Loosely attach the cover to the base then dry fit it all together over the pit so that the cover will fit on the base with all the holes lined up. Once it all lines up on the money attach the base to the floor with Tapcon screws and silicon. 2) I saw a number of reviews where people had a hard time attaching the cover to the base, both lining up the gasket and getting the cover screws into the base without knocking out the retaining nuts into the pit. One good tip in the instructions is to put the screws into the cover holes, then putting the gasket on the screws. Then you just carefully place the cover on the base while paying close attention to lining up the bolts. Use a nut driver to slowly and carefully make sure the nuts and bolts line up, taking care to not cross thread them. Get all of them started, then tighten them down in a star pattern like you were changing a tire. Mine all went in with no problem. 3) There's an extra 1" or so hole in the side of the base that I didn't see mentioned in the instructions. I didn't need it for whatever it's for, so I just took a used gift card and silicon-ed it to the inside of the cover, then used a fender washer and a stainless screw to pull it tight. Worked great. So overall I'm very happy with the product and result. I's buy it again.

I found this Radon Mitigation Basin Cover simple to Install, everything you need is in the box except your PVC fittings, glue and cleaner. I have had it installed less than one week and it meets all my expectations. It took less than three hours to Install and if I had to do another one it would take about two hours. Instructions were very clear and easy to follow and I would advise to read the Instructions several times so you clearly understand what you are doing and buy the correct size hole saws and concrete drill bits. The features that stand out the most is that it is well made by a reputable company and very strong an durable.

I discovered we had high levels of radon in our new home and needed to take steps at remediation. My first step was sealing the sumo pit. The cheap builder cover just prevented someone from accidentally failing into the pit. This one seals it tight! It comes with a wide variety of gaskets to adapt to tons of potential pipe/plumbing scenarios. A feature I really appreciate is the little window so I can look into the pit to see what's going on without having to unscrew the lid. Installation was easy and only took about an hour. I used silicone and Tapcon concrete screws to permanently install it and it works great!

About 30 years ago I had my home tested for Radon with a carbon canister home test. The results came back showing negligible Radon levels so I did nothing about it. Last winter, after an impulse purchase of an electronic Radon monitor, I was surprised to find the Radon levels in my home well above the recommended maximum levels recommended by the EPA. I had a Radon Mitigation contractor give me a quote for a removal system and was quoted a total cost of $1050.00. This price seemed reasonable but after a close examination of the proposal I was not happy. The contractor wanted to put in a very cheap submersible sump pump, build a custom clear Lexan cover, and seal it all more or less permanently. This would make access to the sump pump difficult at best. I wanted a system that made access to the sump pump at least possible. So I searched for Radon mitigation sump pump cover and found the “Everbilt Radon Mitigation Basin Cover” After considerable research, I found a very high quality submersible sump pump, Radon mitigation fan and purchased the cover and PVC piping and fittings to complete the job. As the winter turned to spring, I noticed that the Radon levels in my house started to drop. The levels were still greater than recommended but about half what they were in the winter. I wasn’t sure what caused this, but later I think I found out why. Since you need to attach the cover riser to the floor with 12 concrete screws, you have to disconnect your current sump pump to prevent the discharge pipe from blocking the cover riser from around the sump. Since we had a rainy spring I decided to install the new sump pump. The directions suggested that you clear out the sump of sand and pebbles before installing the new pump. To get the sump dry I ran the old pedestal sump pump past its normal shut off point, then used a shopvac to pick up the pebbles and sand in the sump. The next day, the Radon level in my house shot up and more than doubled overnight. This gave me a clue to the source of the Radon. My sump is supplied by two 4 inch pipes. One of the pipes is much lower than the other one in the sump. The lower pipe is always totally under water before the pump turns on. It appeared to me by exposing this pipe to air by draining the sump, I allowed the normally underwater low pipe to discharge Radon into the house. This also explains why the Radon level was so much higher in the winter. We had a relatively dry winter that allowed the water in the sump to evaporate and be lower than normal. In the spring, rains re-filled the sump slowing the Radon from the low pipe. As I said, you need to drill 12 holes in the floor to mount the cover riser to the floor. The concrete screw instructions suggest that you use a hammer drill to make these holes. I didn’t have a hammer drill but found that I could do an acceptable job using an ordinary drill. The bottom of the cover riser is caulked and it was easy to screw it to the floor. The only mistake you could make here is to position the drain plug position incorrectly. There is a rubber gasket supplied for the seal between the cover riser and cover. The gasket seemed kind of floppy and I wasn’t sure it would be fully over the cover riser between the 8 bolts. So I rubber cemented this gasket to the cover riser to ensure it did not slip too close to the edge and fail to seal. Once you have put in a few bolts you have no ability to make adjustments to the gasket. Installing the cover bolts was my only glitch. The nuts for the cover bolts in the cover riser appear to be part of the cover riser. In fact, they are separate nuts press fitted into square holes in the cover riser. While installing an early bolt, I pressed too hard on the bolt sending the nut to the bottom of the sump. Luckily, they supply a lot of extra parts and I was able to replace the lost nut. I was very careful after that to start the bolts very gently by hand tightening until I was sure the threads had caught. You can’t leave out a bolt or there will be a hole in the seal. The fact that the cover is symmetric gives you eight options for the pipe placement. The rest of the installation mostly involved standard PVC piping. My new sump pump has two cords, one for the pump and the other for the float switch. The grommet supplied with Everbilt cover is set up for only one cord but it was easy to cut a slit with a razor blade into the grommet for a second cord. The total cost of this project was $539.97 for all material and electrical equipment. Once I turned on the Radon fan, after only two days the Radon level measured only 0.35 pc/l which is 11 times less than the EPA standard. I’m 75 years and found this to be a relatively easy project that I completed in a couple of days. I would not have started this project had I not found the Everbilt Radon Mitigation Basin Cover. Knowing what I know now, if I was starting this project over, I would have skipped the purchase of the Radon fan. Since it appeared that the source of the Radon was the discharge pipes in the sump, perhaps just installing a sealed cover would have been enough. If not, the fan could have been installed later. Everbilt supplies a cover to seal the vent pipe if desired. I could test this by turning off the Radon fan and monitoring the Radon levels. I am, needless to say, very pleased with the final results.

Sturdy, good looking topper. I tapcon screwed, and siliconed it to directly into the floor. Without even installing the radon mitigation piping and fan, our basement radon levels dropped from 4.4 to 3.0 pCi/l. I have since installed the mitigation piping, and it was a breeze. The kit comes with extra bushings of all sizes so you can drill extra holes where needed. In may case, I drilled an extra 1 1/2" for a back up sump pump and there was a ready-made bushing seal included. One word of caution, I ordered a new Watchdog submersible pump because my old pump was a pedestal type; The pre-drilled hole for the wiring was not big enough to have the float from the new pump thread through it (I think this is particular to the WatchDog pump, other brands may work), so I had to drill another 1 1/2" hole to accept the float and its wire. The kit did not come with a good plug for a 1 1/2" hole, just the bushing mentioned above.

This product was everything it claimed. More than enough connection options. although I did not install it myself, I worked with my handyman, and went smoothly. He commented how well built this was and wanted to know where to get this from. A great solution for the replacement of an aged and rotting sewer pit cover.

This cover was the perfect first step to installing my radon mitigation system. It is heavy duty and had all the attachments I needed for my piping. 12 tapcons and my hammer drill was all I needed.

The cover was straight forward with installation. It had several options for different pipes like the sump pump. Readings went to zero after all was hooked up. Follow the directions to ensure proper fit and function.

I have bought 2 of these now some I have dual sump pits in my basement.

The start to peace of mind. Get it done and stay healthy.

The cover, when directions are followed, works perfectly. It provides multiple options for mounting needs and exits of tubing. My plumber had problems installing it because he said he didn't need to read the directions. I was able to correct his mistakes and it works very well now. Highly recommended by me, the homeowner. Delivery was delayed a couple of days for some reason.

Reasonable cost and good quality

One of the pre tapped holes does not align with the flange

Great Product. Well built and much studier then simple lexan sheet. Ensure you have space around the sump pit since the cover diameter with the lip is ~25inchs wide so it can hit a close wall possibly. For sloppily installed sump pits it works great. Very worst case you may have to grind some concrete flat to ensure you have a level surface but the lip does have flex. The ability to remove the lid is great unlike the simple lexan lids that get fully siliconed in place. You can remove the lid super easily. The only product improvement would be to have a 4inch NPT port on top versus the 3inch but a simple 3-4inch PVC NPT coupler is no big deal. The view port is great. The red drain plug on the side should be a threaded port not a press fit. Lots of fittings to use different pipe sizes. I am glad HD has this in stock locally. The pro radon supply stores dont like to carry this for some reason. I would buy and use this again.

Haven’t sealed and screwed it to the concrete yet, but have it “dry fit” in place over my sump pit and it appears to be very high quality, and will do the job intended. If this doesn’t lower my basement radon levels enough on its’ own, I guess I’ll need to get a Radon mitigation co. to add on a powered vent stack. But at least this gets me 1/2 way there on my own.

Easy to install. It sealed really well. Read the instructions and put that gasket on first!

The kit came with everything needed to adapt to many different configurations. The cover is extremely strong I stood on it all 225 lbs of me and it never flexed from the weight. Love the see thru window which is easy to remove to test the pump

Very easy to install. Blocks RADON while giving our some a more professionally finished appearance.
