The 3/4" vented loop acts as an anti siphon valve for head and sump pump installations. Installed between the pump and the bowl when used for the head.

Some boat models built in Florida are equipped with a sump, a box that collects the outflow from showers etc. A single pump is used to pump the water collected in the sump overboard. Often a 3/4" hose is employed. In these cases you will find this 3/4" anti siphon valve in the outlet between the pump and the through hull valve.

Molded Marelon offers superior strength and corrosion resistance. Marelon is lightweight, corrosion and electrolysis free, ideal for thru-hull valves. Marelon is a modern material formulation of polymer composite compounds that uses resins and additives to produce an extremely strong marine-grade product that will not deteriorate like traditional bronze marine plumbing parts.

An anti siphon valve introduces a small amount of air into the hose whenever a small suction is detected. This breaks the siphon and prevents flooding your boat. There is a tiny rubber "duck bill" valve that is critical to its proper function. If the rubber gets old and stiff it may not function properly putting your boat at risk.

Order the replacement part below under "May we also suggest".

Always measure the i.d. of the hose before ordering. Although we believe the boat categories this part is listed are accurate, there is no guarantee that your boat was built exactly as expected.
