    Replacing original 14 yr old pumps. does anyone know the output hose size? Didn't get a chance to pull one this weekend

    And related... Any problem setting a high water alarm sensor at bilge locations and wiring all to one alarm? Yes I won't know which area is high but I would still be on the way....

    Any thoughts are appreciated

    What kind of pump do you have? Rule 1100 and below use 3/4" hose. Rule 1500/2000 gph use 1 1/8" hose, Larger Rules 3700/4000gph use 1.5" hose. Johnson pumps use 3/4" exclusively on all sizes I believe. Use the super switch not the cheap switch if you change them. Also use heatshrink butt connectors and make sure to heatshrink them, as well as tie wrapping everything.

    Pumps

    I replaced 2 of the 3 last year on my 450 Voyager. Mine are 3 Rule 2000 gph.

    Your high water alarm is set to a float switch mounted high (about 4") so it alerts when you have water that your pumps aren't keeping up with. That float switch should be connected to your lowest blige pump along with another float switch at regular level. You don't want it on all pumps. It'll drive you crazy. The regular float switches are generally connected to lights.

    Final got mine out. It is a Rule 2000 as Rich thought. So as you suggest NYCAP, as the boat sits idle, would the lowest bilge be aft or amidship? I assume that while running, aft would be lowest. So if setting one alarm is amidship best? Thanks again!

    It all depends on your boat. However, unless there's a high water float switch already mounted I'd be inclined to mount it aft or in the engine room, wherever water is most likely to accumulate while underway. That's when it's most likely to do the most good.

    High water sensor

    I have a high water sensor mounted 2 inches above the stern bulkhead weep hole under the genset below the battery switch for the generator. Mine is integral to an onboard alarm system that uses cell phone technology and siren as an alert. Mine has gone off 2 times to save the day once underway when a sea water hose to the intercooler burst and the other at the dock when I was washing the bilge after some service. This location seems to be the lowest on my boat and works for me.

    We have a similar system on the Hatt so we're alerted by text and e-mail for high water and AC loss. Good feature, especially if you'll be away from your boat for extended periods. When I ran marinas I remember many times walking past a boat to hear that low beep, beep, beep that 100 people walked by without noticing. Although for most people that will suffice as long as it alerts them when on board. I also chose about the same location.
