Will replacing a a sump cover with a openings in the top with this sealed model reduce the radon levels from 4.6 to below 4?

By itself it won't do anything unless you create an active ventilation system. You will need an external powered fan to draw air from the sump to outside of the home through the cover. It is very sturdy and well designed though.

Hard to say, sorry for that unclear answer. I wouldn't be surprised if it did, it depends on what other entryways it has. It's all based on pressure. If you cap it off, you're putting a cap on the 2liter soda bottle. If the bottle doesn't have another hold in it, or in the case of your basement, cracks in the foundation floor, where the floor meets the walls, etc, then yes, you should see a drop. The only real way to be sure of a drop is to exhaust the radon, a project you'd clearly like to avoid. This is a 5 star cover, but understand to do it right, you'll need to drill some holes in your floor around the sump opening and then caul/seal the bottom. Hard to say, sorry for that unclear answer.

Good chance. Sump pits or any crack in the floor can be a source of Radon. This is the easiest place to start since it is usually a large opening.

Should reduce radon entering the home but if u have that level I'd recommend installing a vent system

Sorry! Yes I didn't answer the question. I just thought it is the product review. It should be some problems 1) the pipes have air leaking or ground is not sealed well 2) fan is not so powerful.

It's 1 1/4. I don't think that will cover it . I would suggest 3/4 bulkhead would work for you but I don't know that it's outside diameter is 1.5. I think so but ask someone who bought a 3/4. 1/2 does. Cover a 1.5 hole it just won't have a as good as a seal. It will seal . But ask someone who bought a 3/4 one see if it has a 1.5 o.d. first if it's bigger than go with the 1/2 it will work

While not necessary in this scenario, I suggest you go ahead and install the entire seal to act as an additional dust blocker. It really does a fantastic job and only takes a few minutes to install.

no.Here is a link to the instructions to replace the seal on that model.http://www.dometicsanitation.com/QBank/EPiServer/SeaLand/Manuals/Replacement-Parts/300-310-320-Flush-Ball-Seal_6412.pdf

I have not noticed any difference, I don't know technically if it does. I have not found any where that has allowed air to pass being that it had pulled away . I was just running new water and sewage lines in the basement and was inspecting for air leaks of places that I missed on the original install. I found none. You might want to contact the manufacture for technical data. They were very helpful and addressed all questions. I used the closed cell exclusively . Full fill . I can tell I am BLOWN AWAY with the low cost of my heating this year so far. I have used only 1/4 tank of oil. I keep that house at 70 degrees. I live in western pa. Hope this helps

I am not sure. Are the lid deminison the same and just the depth different between the 4 quart and 6 quart? I have a six quart so I really can't tell you what size sealing you need

no it won't. it seals concrete, meaning, water won't flow through the pores of the concrete you treat. your problem is not these pores--your problem is the small gap between 2 slabs of concrete. the radon seal is the consistency of water, and will not fill the crack (the joint between wall and slab) you are talking about.

I would. The trick may be to get the material into the crack without further cracking from the pressure used in the application (an epoxy caulk may do the trick). Also, the plastic material used to form your skimmer box is likely deteriorated so this product may act as a catalyst in this decomposition. Try a small swatch on the inside of the lid to your skimmer box. It should be the same material and any decomposition would be visible within a few days. Just a thought!

I removed the old caulk and applied a thin bead of transparent silicon caulk and smoothed it out to be mostly flush. I then applied this strip on top of that and then used the remaining transparent silicon caulk to seal the grout lines along the top. Based on reading the reviews I think sealing the strip after you apply it with transparent silicone caulk is a very necessary step. Just spend some time wiping up the excess and you won't notice the transparent caulk, but you will have piece of mind that the strip will be water tight.

It will work, just not as well. The biggest robber of heat from your pool is actually the wind, not the outside temperature. So 4 feet of exposed area is not going to completely negate having the cover, but also not as good as it could be. Hope that helps.

I would not install this inside the house because if the outlet is restricted or there are leaks, you'd be pumping radon into your house.

I would advise sealing any major openings or cracks, but that may be hard to do in an attic. I used mine in the basement and was pleased with the results. Be sure to wear eye protection when activating spray!

I cut a round of 3/4 inch mdf just slightly smaller than the diameter of the lid. I placed that on the underside of the lid and then bolted the dust deputy to that. I used a piece of rubber pond liner I had laying around for a gasket but you could just seal it with caulk. I use it with a 20 gallon craftsman shop vac and have no problems at all with the lid collapsing inward. I hope this helps a little.

Definitely, NOT! Radon Seal works by a chemical reaction between it, and the cement in concrete. It does NOT work unless it's used on clean, porous concrete. There is less cement in concrete blocks (also known as cinder blocks) so more radon seal is needed in this case. NEVER use RadonSeal on anything but cement based, porous concrete walls, floors and blocks. Sorry!

Sorry, I did not notice that your question was about a seal from above the unit. Still - no provision for it. You will have to cover the opening with your own materials - plywood, plank etc.
