Siphon Breaker Kit

Siphons can sink a boat. We offer a kit that will keep this from happening.   A typical situation is a bilge pump which turns on when the water level operates the bilge pump switch. This pumps the water overboard and in the process, removes all the air from the pipe leading from the pump to the outlet. If the outlet is high enough above the waterline, when the pump stops, air sucks back in the outlet as the water in the pipe drains back into the bilge. The only problem with this arrangement is some of the dirty bilge water dribbles down the topsides of your boat leaving a nasty stain. To reduce this problem, the outlets are often placed just above the waterline, or even below it so the discharge is out of sight. But now, when the pump stops, there is no way for air to get back in the pipe, and as the water drains out back into the bilge, seawater comes back in the outlet and your boat starts to sink. Even outlets just above the waterline can cause problems when the boat is heeling unde
