quick question. i am installing an automatic bilge pump. the manual bilge pump is in a side compartment, on the starboard bench. it has a hose that runs to it, from the lowest point, just above the keel bolts. this is, of course, where i am putting the pump. i was going to route the hose, from the pump, where the manual hose is routed. that would bring it out into that storage compartment.

there is a small well, that extends below the level of the cockpit sole, where any cockpit water is dumped and runs out through the hole in the transom. is there any reason i can't just put the through hull in the side of the bench ( higher than sole level ), dumping any water into this well, so it runs out of the hole that is already in the transom.

i think it's a great solution because it keeps me from adding another through hull and i won't have to worry about water backing into the hose. i figure, if i have that much water in the cockpit, to where it can backflow into the pump, the backflow is going to be the least of my worries.

thanks

Bilge water may not be as clean-smelling as the rain and spray that drains from the cockpit. Our electric bilge pump pumps into the anchor locker, and drains from there, but it is up forward by the shrouds so we don't care so much.

Anything that saves another thru hull could be a good idea.

Can you test it for a while and if it doesnt work then do the thru hull?

If its stinky a bucket of water with flush the cockpit.

sure. if it doesn't work out, i can always add a through hull. i am thinking like you: one less through hull can't be bad.

That is a really interesting idea! I will be re-thinking my installation plans!
that's pretty cool. it seemed logical, to me.

As long as the sump is low enough that you don't end up puddling in the cockpit it should be fine.. but you could also direct it out the transom at a similar height and avoid water/smell in the cockpit. The added bonus with that would be an audible indication that your pump is running when you hear the splashing aft.

thayt was my other option, actually. the sump is pretty deep and sizeable. not sure if i have a pic i can post depicting it. Michael might have one, in the photos he posted in his profile, for me.

i like this option, though, because it avoids another through hull...less risk of back flow. i would add a check valve but the pump instructions expressly say not to do that.

got it done! it works great and it looks good. i will post pics after dinner.when i bought the boat, it had no hatch or hatchboard. so, it had been rained in. they had maintained it with a pump, however. it still had about an inch of water in the bilge. it hasn't taken on any more, since i closed it in. so, as soon as i flipped the switch, it pumped out the water. it worked perfectly. poured into the well and out of the boat. no fuss. no problems. and no back up. tgat pump made short work of that little bit of water. i didn't even have time to snap a picture until it was just a trickle coming out.

Great !

How are you running the pump, from shore power or a battery..??
battery. i wired it permanently to the switch panel. at present, it's the only thing hooked up. all the rest of the wiring was BS harry home owner junk. really bad. small ga wires leading from the power source to heavier ga wires. poorly crimped, hard plastic automotive connectors ( the kind i never ever use on cars or bikes). not even any electric tape at the crimped ends. fire hazzard. getting ready to begin rewiring the whole thing.

i used a Rule automatic bilge pump. not the type that cycles every two minutes, though. the type with an actual float. it's rated at 1000 gallons per. i used tinned 12ga wire and the appropriate connectors with the adhesive in the shrink tube part. then i used liquid electric tape over the joints. i routed the wiring away from the hose so water is less likely to run along the wires.

once i get the pics on photo bucket, i will post some pics of the well and the new through hull ( which is not through the hull:D ). not sure, yet, how the pics turned out. you may or may not be able to see the last bit of water coming out. it didn't take long to clear out what little water was there.

by the time i got the pump ( $89 ), the through hull, hose, wire and connectors, and battery, it cost me around $200. as everyone knows, it adds up quick.

i am not going to buy the wire or connectors i need, for the rest of the system, from west marine. that would cost me a fortune. i am going to see if i can find a better source and buy bulk. it's more cost effective that way.

i also need to find some interior lights, too. 3 or 4. again, not from west marine. too expensive. going for LEDs. brighter with less power draw and heat.

Fuse?

i'd never run anything without a fuse. that's asking for disaster. the switch panel is set up with glass fuses built in. the hot wire runs to the top of the fuse. then a wire leads from the side of the fuse to the switch. it's a nice panel, actually. it's just that all the wires, from the switches out, are done with mickey mouse style.

here is a pic of the well. the new not-through-the-hull through hull is on the left of the pic. unfortunately, by the time i snapped this shot, the water was done running out of the through hull. in the pic, you can still see the water draining out of the well, though.

starting from the outlet, going in, the line 90s up, to keep water from flowing back in ( an unlikely possibility due to location, in any event ), then levels out to run to the pump. of course, it has to drop down into the bilge, after it reaches the middle of the boat. if you guys like, i can snap some pics of the rest of the set up.

An added advantage of running a bilge pump into the cockpit: If your feet suddenly get wet, it's a dead giveaway that something needs attention.

lol. that is true. if my feet get wet it will be a serious problem. the water that pumped out of the bilge, while not a ton, pumped out fast but it never came close to filling the well. if that well fills and begins to fill the cockpit, i think last rites might be in order. lol
