Adding automatic bilge pump to manual bilge pump

Ok, I have a manual pump that is operated from the cockpit. I would like to add a second automatic pump in the bilge. I think I understand the wiring end. However, do I need to run a second pump hose out of the boat, or can I rig a Y valve on the stern side of the manual pump, and shut off the manual side when it is not needed? Also, should I add a check valve in the hose, close to the pump?
thanks!

Re: Adding automatic bilge pump to manual bilge pump

You could probably add a two way valve. Leave it open to the autobilge normally, but when you want to manually pump the bilge, flip it over to the manual bilge pump..

just do NOT forget to flip it back to the autopump when you are done

Check-valve - can't confirm but read that ABCY does not recommed check valves in the bilge outlet line. I just removed the check valve in mine.

Not sure the reason you want to do this, but I would only join with a Y valve just before the thru-hull, and only when the hoses are as close to horizontal as possible. Otherwise the auto bilge pump will need to work harder to push the water up to two hoses and you will have a lot more standing water that will run back down once the pump turns off.

Adding automatic bilge pump to manual bilge pump

I set up my Oday 272LE this way when i bought it. I keep the Y valve to auto bilge the whole time and use the manual bilge only for emergency ops if the need should arise or just to test it monthly. They key is remember to move the valve to correspond to manual pump or electric bilge mode obviously. a reminder by the switch is a good idea.. I didnt install any check valve as i wanted utilize the KISS principle for any bilge system.

Re: Adding automatic bilge pump to manual bilge pump

What happens if you need to use both pumps at once? That may sound scary but a possibility. Do you have a manual pump below? Why not? I realize that it's a 27 footer. So this may be a little bit to redundant. But, You could be 10 miles off-shore get caught in a storm and get swamped; then lose power. Is your electric bilge going to work? Probably. Do you feel comfortable being in the cockpit when you may have issues down below?

I'm a believer in a manual pump up top and one below where they are easily accessible and Piped separately if possible. Sure that one below might not be pretty; but it's no different then the fire extinguisher. I run two electric pumps as well. One fully auto and one bigger pump for emergencies. (My boats a little bigger) I plan as if i have lost all power.

Sorry to be the pessimist. Just my thoughts.

Re: Adding automatic bilge pump to manual bilge pump

I agree I would use a separate thru hull for the new pump. Adding Ys and check valves restrict flow and on a de-watering system the fewer restrictions the better. And has been said you may need both at once.

Re: Adding automatic bilge pump to manual bilge pump

good points on being able to run both systems at once.

I myself like to keep holes in the hull to a minimum.. but sometimes you need to make an exception.. and I think this is one of those times

Re: Adding automatic bilge pump to manual bilge pump

I hate holes in the boat, but having them above the water line is less scarey. Having two or more completely redundant systems is not a bad thing.

Adding automatic bilge pump to manual bilge pump

I actually have do have a secondary manual only pump below aswell as the primary manual pump (and would assume all boaters would so i didnt make mention of it) making for three pumps with the electric one and dont sail alone but if it ever got to the point that even two out of three pumps are actually necessary i think it would likely be a lost cause at that point and time to "pull the D ring, ride the rails and hit the silk"
