Have one with audible and visual alarms. I test it now and then and the dogs go flippin' nuts---a good back up.

The Hatteras came standard with one in each of four bilges, with light and alarm at each helm and a horn and test button.

Our boat came standard with 3 pumps, each with indicator lights both below and on the fly bridge. Additionally it came with a larger-capacity high-water pump. If that cycles alarms sound at both stations.

Coincidently I had to pull a transducer yesterday. Our bilges are always dry so the pumps get no activity. I make sure to test them and their switches once a year. Imagine my surprise when the water flooded right over the switch and the pump sat there quietly. I wacked the switch with my hand, it came unstuck, and the pump started.

Lesson #1 learned. Lesson #2 is that even with all 4 pumps running I doubt I have enough capacity to keep up with even a 2" hole a couple feet below the WL. Impressive the amount of water that'll admit.

So true about keeping up and ultimately the underwhelming performance of electrician trick bilge pumps.

For any newer boaters out there...don't worry TOO much...

The practical reality is to know enough damage control to greatly reduce the inflow to where it is more than manageable for the pumps.

High Water Alarms

Four bilge pumps.

One that does all the work. A rule with an external float with a counter.

The second that is hooked up to the horn and a buzzer on the switch panel. That's the Hail Mary pump.

The third is in the sump under the engine. If the water gets this high I'm screwed.

And the fourth I never hope to meet a Whale Gusher hand pump.

The PO installed a jabsco water pump as a super low suction, to just about completely dry out the entire bilge. This is on a manual push button switch.

I made sure after purchase that NONE of my bilge pumps were the 'automatic' type that regularly run, and if they detect higher amps (indicating load) they keep running until no load is detected. Nothing sounds dumber to me than electric motors running uselessly when the boat is on the mooring.

Six electric bilge pumps on board, two for each compartment.

Plus an engine driven pump with a bilge manifold accessing each compartment.

Plus a manual pump sharing the bilge manifold.

I also like plenty of alarms.

Audible and visual alarms indicate bilge pumps running, with an additional siren for bilges flooding.

Among the many alarms on board only three are sirens, the watch alarm, ER fire and of course, flooding.

I do have a Johnson Pump alarm, the sensor is mounted about 6" higher than the bilge pump float switch, red light and horn sounds on flybridge.

I sort of have one. My primary bilge pumps (2 1,500 GPH pumps) have float switches at the lowest point of the bilge. I also have a 4,000 gph pump wired to a float switch located above the tops of the other pumps. That pump is loud enough to act as its own alarm since I can hear it underway. Fortunately the only time it has ever come on has been during testing.

They are easy to make if you want. I use a pezzo alarm from radio shack and wire it into a float switch. Mount the float high enough so it doesn't come on unless obvious flooding. Very simple for a great piece of mind and the tiny little pezzo alarm will wake you up quickly!

Mouse trap high water alarm.

Mouse trap, horn, wire, asprin.

Wire it up keep a good supply of asprin handy.

Old school.

All boats should have high water alarms, with really really loud alarms.

Actually, Dingy ' s not so much but

I have 3 bilge pumps all controlled by individual float switches and each can be manually turned on at the helm. I installed an additional float switch about 3" above the center bilge pump which is connected to a siren and a red led flasher both located on the radar arch. Wired electrically in parallel is a panic switch located in the master stateroom. The siren is so loud that I installed a siren cut off switch at the helm so as not to be so distractive I couldn't talk on the radio. All this is hot wired to the engine start batt with a fuse of course. Has never activated.

I have two.
1) Is a high water switch connected to a buzzer at the help. The switch is a float switch in a cage mounted about 6" above the bilge switches/pumps.
2) Is electronic switches in every bilge compartment, engine room and lazzertte that have a separate electronic buzzer in the hallway of the lower level. The buzzer is load enough to hear while engines running from the pilothouse. I installed this after a freshwater line to a shower leaked into a forward bilge. Water 1/4" sets off the alarm.

I had them make it for me. Copy and save the picture I posted. Send them (Rodney) an email (aqualarm@live.com) with the attached picture. Tell him they made it in July 2015. Customer name was Ted Green.
