Well Cap Kit with Disinfection Port

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.
