Your Well Cap Is the First Line of Defense Against Contamination. Make Sure It’s the Right One.
Most well owners never think twice about their well cap until something goes wrong. But in our 30 years of conducting well inspections across the Northeast we have seen firsthand how an unsealed, damaged, or poorly designed cap is one of the leading causes of bacterial contamination, insect infestation, and surface water infiltration in private wells. The right cap is not just a cover. It is one of the most important structural protections your well has.
The ETR Laboratories Premium Well Cap Kit was developed by our own engineering team, the same team that has conducted over 1,000 in-field well inspections, disinfections, and cap installations. We started with the trusted Campbell 6-inch well cap and modified it specifically to solve one of the most common problems we see with standard caps in the field: making routine disinfection unnecessarily difficult.
Most well caps require you to remove every bolt and fully lift the cap off the casing every time you need to disinfect your well. Our engineering team drilled a custom twist-off disinfection port directly into the cap, so you can complete the disinfection process without removing the cap at all. It is a simple modification that makes a real practical difference for any well owner who wants to stay on top of routine maintenance without calling a professional every time.
What Is Included
The ETR Premium Well Cap Kit includes everything you need for a complete installation with no additional purchases required. The kit contains the modified Premium Well Cap with built-in disinfection port, one half-inch to one-inch converter nipple, one one-inch to one-inch converter nipple, three metal hose clamps, six half-inch nuts, four silicone shrink-wrap tubes, four silver wire connectors, a one-inch diameter plastic pipe, a complete illustrated installation manual, and our Well Disinfection Kit with EPA-recommended chlorination agent and a follow-up bacteria and fungi test to confirm your well is clean after installation.
Cap Specifications
The Premium Well Cap fits any standard 6-inch well casing and conforms to Water System Council PAS-97 standards. The top of the cap can be removed without affecting the seal, conduit, or wiring, making future maintenance and inspections straightforward.
Installation
This kit is designed to be installed by any reasonably handy homeowner. The illustrated manual walks you through every step clearly and our customer service team is available by phone to answer any questions during the installation process. You do not need to be a plumber or well contractor to complete this installation successfully.
Why This Matters
An unsealed or compromised well cap is one of the most preventable causes of water quality problems we see. Insects, rodents, surface water, and airborne contaminants can all enter a well through a damaged or improperly sealed cap. Installing a quality cap and keeping up with annual disinfection are two of the simplest and most effective things a well owner can do to protect their water supply year over year.
This kit replaces a cracked, loose, or poorly sealed well cap with one designed to keep insects, rodents, and surface water out. A damaged cap is one of the leading causes of bacteria problems in private wells we inspect.
It also suits owners who disinfect their well every year. We drilled a twist-off disinfection port into the cap, so you can add chlorination agent without unbolting and lifting the whole cap.
The cap fits any standard 6-inch well casing. If yours is a different size, call us before ordering.
The kit is made for a reasonably handy homeowner, so you do not need a plumber or well contractor.
Our team can answer installation questions by phone while you work.
The cap itself is hardware, not a lab test. The included Well Disinfection Kit comes with a follow-up test for bacteria and fungi (yeast and mold), which confirms your well is clean after installation.
The cap kit ships free to you. When you send your post-disinfection water sample, use the prepaid label in the disinfection kit.
Under our money-back guarantee, physical products such as well caps may need to be returned to process a refund. We will send return instructions if you ask.

“The test was simple—collect a water sample from a faucet in the home. We sent the test to the lab and received a water quality analysis within a few days. The test included analysis of the water sample for the presence of: coliform bacteria, E. coli, iron, lead, pH, turbidity, and nitrates/nitrites.”

“Incredible lab, they really care about their customers. As someone who doesn’t know a whole lot about water quality, they took their time to help me understand everything about my water quality situation.”

“I’ve used ETR for several tests, both water and air. The test kits are easy to understand and the reports are very comprehensive. But what really makes them stand out is their quality of service. There is a lot of terminology in these reports that I don’t understand, but their staff is very knowledgeable and always available to assist. They really take their time to review the results with you on the phone, and answer any questions you may have.”
