EverPrime from Waterless Co., Inc.
EverPrime® is a proven drain odor prevention solution designed to stop sewer gas smells before they escape into restrooms, laundry rooms, and other building spaces.
By preserving the water seal in floor drains and plumbing traps—even in unoccupied or low-use buildings—EverPrime helps protect both indoor air quality and occupant health.
When drain traps dry out, they can release foul odors, harmful bacteria, and dangerous gases into the air. These issues are common in vacant properties, seasonal homes, and commercial buildings—and they can lead to tenant complaints, health concerns, and costly maintenance calls.

“I use it in the drains in our Florida house. It works great, and after a couple of months of dormancy, the house doesn't stink.”
Important Clarification from Waterless Co.
One reviewer experienced a clogged sink after use. It’s important to note:
EverPrime is not a drain opener.
It is an odor-blocking liquid designed to prevent sewer gas from escaping when the water in a drain trap evaporates.
Our recommendation:
If a drain is clogged, use a drain auger to clear it first. If that does not resolve the issue, consult a plumber before applying EverPrime.
“Great product.”
