If you have an ugly, open or unsealed sump in your basement, it's an invitation for radon gas, odors, insects and critters of all sorts as well as a hazard to small children and pets. The Original Radon/Sump Dome™ can make your home healthier and safer. It's easy to install and preserves access for servicing your sump pump and controls. Cover and seal your sump with The Original Radon/Sump Dome™ to mitigate those issues. Tell your plumber or radon remediation company that you want The Original Radon/Sump Dome™ made by Jackel.

The Original Radon/Sump Dome™ comes with the base ring, split cover with 3" radon vent flange, gaskets, and hole drilling template.

And we don't just sell you the Dome!

  • Basepump Residential Sump Water Alarm Included too!
Basepump High Water Alarm with Float Switch

The Basepump water alarm is a single point, battery operated water alarm that sounds the alarm when water lifts the float. It has an 85 dB loud alarm that should be able to be heard from the basement.

This is the same alarm that is INCLUDED with every Basepump water powered backup sump pump. If you bought a Basepump there is no need to order this here unless you need a second one.

It uses a common 9 Volt battery that is designed to last up to one year in stand-by mode. It chirps to alert you to a low battery condition. There are "dry contacts" inside that may be used to connect to your home security system or to a simple auto-dialer. These may be able to notify you of a water problem before it becomes a bigger issue and much damage is done.

The sensor float on this alarm is mounted on a stainless steel bracket in the sump, either on the sump pump pipe, or on the side wall of the sump. Either way, you set the position based on the water levels in the sump.
