    Default Manual bilge switch or float?

    I don't remember seeing many float activated bilges in jets over the years but I did see one in action at the TP memorial. The float switches work great for hulls with deep bilges, but could I get away with a float on ye ole 19' Hawiian? With my shallow bilge, it seems like a lot of water would be needed to activate the switch.

    I have one of the cheapo floats in mine, 18' bubble deck, works OK, they make a sensor with a relay too, it uses the waters conductivity to pull in a high impedence relay, work killer, I'll try to find the link..

    ive got three automatic bilge pumps in my 19 daytona and the work great i love them they cost about 100 a piece but for me wont go to the manual bilge its nice to just pull the ACC switch and it runs when needed

    probably would save the bilge pumps life alittle bit too to have them auto, that way it's not sitting there sucking dry when your cruising and forgot you had it on. I've never used a auto one, i plan on installing one though. Right now i have two 800GPH pumps on a manual switch. The pumps with a switch built into them seam nice.

    Both.

    I left the manual switch in, and the float setup wires arround it.

    No GPS alarm in the middle of the night if I am asleep in my tent and the boat needs to pee.

    Mine goes boath ways. I guess I'll have to look at the 3 I have for my new ride. But the one in the old boat has a float and I have a switch on the dash. You might want to look to see if you have a 3rd wire on that bilge pump.

    When researching for seaplane project a couple years back, the water sensor mfr said that fresh water may pose a small problem. They were designed fro salt water environment, but will work is fresh water, but not as well. We did end up using them in the project, 10 bulkheads / 10 sensors, flooded each compartment for testing. It was decided to add a safety float once the water rose to the top of the bulkheads, to turn on all pumps. We incorporated a timer in the set-up, so that if the auto pumps exceeded a 1 minute minute duty cycle, it would turn on a white strobe light. This would alert the owner to a problem.

    I've had the same automatic Rule 500 pump in my boat for three years. Some say they're no good, but mine works great and always has. It looks exactly like the manual pump from Rule, but has a three wire hookup rather than two. I've got mine connected so that I pull the knob at the beginning of the boating day and leave it on. The pump comes on and does a check for water every couple minutes. If it feels the resistance of water it pumps till it's dry then shuts off. If no water it just turns itself off. You can leave it on over night no problem if you're at a lake and want to leave it in the water. Uses very little battery. Every once in a while I'll forget and leave the knob on. I've been out in the garage three days after a weekend outing and heard the pump kick on checking for water. Doesn't seem to hurt it and the battery is still fully charged. You can also wire it to a second switch or dbl pole dbl throw to override the automatic feature and make it work as a manaul pump (what the third wire on the pump is for). Personally I never found the need and just use the automatic feature all the time.

    I actually bought the thing by accident. Thought it was the old manual and then when I got home I started wondering why it cost 40 bucks instead of 30 and started reading. I figured what the hell and tried it out. Won't go back to manaul again.

    I will say this..........the first one I bought got some grass caught in the impeller and burned up. On the newer models they put a stainless steel screen at the base/water pickup so it can't happen again. I do pull the screen out once a year and check it. I just clean it up and put it back in and good to go.

    Highly recommended.

    Rule's description of how the thing works.

    Rule Automatic Bilge Pumps
    Float switches are not required for these fully automatic pumps. Controlled by computerised operation, the pump will turn on every 2.5 minutes for about 1 second to sense for water. If water is present, the pump will sense resistance and continue to run until all water is removed. Power use in the checking mode is minimal for the peace of mind that this range of pumps offer.

    I've got a float activated bilge pump in my 18' Avenger. Fairly shallow bilge & water only gets 2, maybe 3 inches deep at the most before it turns on. I put it in there in 2004 when I bought the boat & its worked great... Make sure the pump is secure though, if you go that route. When I tested it in the driveway, the pump just tried to float around without activating the pump, lol....

    Default 3 pumps

    a side note for tunnell boat peeps, you only have to get one w auto switch, put it in the center and wire the two outside ones with it and when the center one(auto) comes on it will light up the other two as well.

    That's smart. I don't think in terms of tunnels so it never ocurred to me. Makes sense and saves money.

    I got the exact same one. Came with my boat. Have had ZERO issues and keeps my boat dry... left my boat in the lake for a week and just left this on and never had an issue. I think they are only like 30-40 bucks.
