Description
Overview

Compatibility and Fitment
E-Treat Concentrate works in both fresh and salt water flush systems, making it versatile for different vessels. It suits portable toilets, standard marine toilets and larger pump-out installations. Because the formula is safe for plastics, hoses and fibreglass, you can dose directly through the toilet bowl and flush it into the tank without concern.
Compliance and Safety
Always follow the safety directions on the bottle. Wear gloves and protective glasses when handling the concentrate, and keep it away from food and drink. Store the container upright in a cool, ventilated space. Dispose of contents only at approved pump-out stations, and follow all local rules on sewage and greywater discharges.
Marine Applications
Boaters can rely on this product across a wide range of scenarios. Cruising yachts, liveaboard vessels, trailer boats with portable toilets and powerboats with holding tanks all benefit from regular use. Because the formula is pump-out compatible, it ensures compliance in marinas and waterways where direct discharge is not allowed. With continued dosing, the system stays cleaner and odour free.
