Forespar MF842 Vented Loop

Forespar MF842 Vented Loop - Essential Anti-Siphon Protection

Ensure the safety and integrity of your vessel with the FORESPAR MF842 Vented Loop, a crucial component for any marine plumbing system. Designed to prevent catastrophic water siphoning, this accessory provides critical protection against flooding and the potential sinking of your boat. It is an indispensable safety device for all bilge pump, toilet, and engine raw water cooling systems installed below the waterline. By allowing air to enter the line when the flow of water stops, the MF842 effectively breaks the vacuum that can cause water to flow back into your hull.

Vented loops are vital components to any onboard plumbing system reducing the risk of sinking or flooding.

The glass reinforced composite MarelonTM Vented Loops allow air to enter the lines preventing that dangerous back siphoning effect.

Use above the waterline on your head discharge system bilge pump the engine gen-sets air conditioners ballast tanks or other equipment.

Vented loops help make sure your boat stays afloat after the pumps are turned off.

Engineered for reliability and longevity in the harsh marine environment, the Forespar MF842 is constructed from a proprietary glass-reinforced composite polymer. This advanced material offers superior strength and durability while being completely immune to corrosion and electrolysis, a common point of failure for traditional metal fittings. This means you can install it with confidence, knowing it will provide consistent protection for years to come without the maintenance headaches associated with bronze or other metals. Its robust construction is designed to withstand the constant pressures and vibrations found on any power or sailing vessel.

The simple yet highly effective design incorporates a one-way duckbill valve that allows air in to break the siphon but seals tightly to prevent water or unpleasant odors from escaping into the cabin. This low-maintenance valve system is renowned for its reliability and is serviceable, ensuring your plumbing systems remain secure and fully operational. Protect your investment and gain peace of mind by safeguarding your boat’s critical systems with the industry-leading technology of a Forespar vented loop.
