SUBJECT: # 19314: bilge pumps
Submitted by Tom P. (64.12.104.47) from NEW YORK on 3/12/2001 7:50:00 PM
Hello All, I am prety new to this board and have a question about bilge pump's set up's. The previous owner had the aft and rear bilge wired thru a switch in the dash. I was thinking about just doing a hard wire to the battery with a fuse. Is there a reason I would want to have the option to turn the bilge pump's on with a dash switch ? They both have there own float switch !Thank's for any guidence....

With the switch set up as is, you can easily check that the pump is actually working before you find out that the float switch isn't.

I have two bilge pumps and two switches(both pumps in the bilge)No fuse, reset breaker.
One switch controls pump select, Large or small
One switch contols auto (float switch) and manual(bypass float switch and turn on pump)
If something happens to the float switch, doesn't work, or the fuse blows for some reason, I don't want to be without pumps to bail my boat.
I'm sure I could improve my setup by adding a fwd pump which may do very soon.
Try not to use fuses in critical systems such as bilge pumps. Circuits breakers that you can reset are much better. When you need the pumps on you don't want to wondering why the float switch is not working or is it, you want the pumps on.

caprtharv (207.243.136.35) from FLORIDA says Pumps
The proper way to wire a bilge pump is to have the float swtch "hot" all the time, so if water does get in, it will automatically be discharged. There should be a wire run to the dash from the pump side of the switch to a manual switch to either override or test for pump operation. A secondary benifit of this is that you can wire a lamp and/or buzzer to it to alert you whan the float switch activates, thus alerting you to a leak, or broken hose. My offshore boat has 3 pumps wired this way. When I am underway, the bilge is about 5' below me. having this auto system with the monitor function gives me piece of mind. And, yes, it has alerted me to problems that were easily solvable. If they were left alone, they could have been major.

You need the manual switch, believe me. My float switch quit working one time and by the time I figured it out I had alot of water in the bilge. Flipped the manual switch and cleared the water out.

Good advice so far. A couple of more things to consider as this is not anyplace to try to save money. The light or buzzer wired into the float switch is a good idea. Wish I had thought of it before I got my boat set up. I put a third float switch in mine, and wired it into the horn. Now if I get excess water in the bilge, the horn blows. If I don't hear that, I'm already sunk.
