        Q:Any tips for getting the cord grommet into the hole cut out for it? I cannot get it to squeeze in there. It seems like either the hole is too small or the grommet is too big.

          Significantly Reduced Radon
          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.

            Great to cover sump pump and setup radon fan
            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.

              Radon now at safe levels
              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.

              GREAT PRODUCT
              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.

                What I've been looking for
                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.

                  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.
