stern bilge pumps

thinking of fitting a bilge pump to the stern and wondered where do you get power for it. all my cables run in a tube from helm to stern so difficult to tap into.
all suggestions very welcome.

I'm guessing the best place will be from a 12v battery.

Both my pumps are wired to the console switches which in turn goto the batts.

Surely there is room for some 12-14awg wire in the tube?

Both mine go through the deck glands along with all other cables.

Lube lots of lube... and a draw wire or rod, wire isnít stiff enough to push through a conduit....

Google cable puller.

I'd never seen that cable lubricant before but if £5.65 saves any more than about 10 minutes of swearing, then it will be worthwhile.

When you have pulled the runs I have pulled through tortuous duct runs you will wonder how you ever managed without it!

used to be hard to find but now even screwfix sells it....

ďMore lube, more lube, more lube, you can never have too much lube...Ē

Just apply after taping the draw line on......

Pulling lubricant? That is a wind up surely! If you are having to pay for pulling lube I wouldn't waste it on the bilge pump

Bit of soapy water will get cables through the tube no worries and I would be surprised if no rope there you haven't noticed to pull the cables through.

See if you have a cable/wire already running in the conduit that you can disconnect. Attach the new wire for the bilge pump and some strong string to the disconnected cable and use this to pull the two others through. Then use the string to pull the original cable/wire back to where it was and reconnect.

Top tip, add another string to the final stage and leave it in the under deck conduit tied off at each end in case you ever need to run another cable/wire through at a later stage.

Good luck

Andy

Thought about just buying a new boat with a bilge pump?

Too much hassle this lot.

Talcum Powder works great and is cheap. If you dont have a pull through cable or string then disconnect something and put a length of small rope, cable or string to the disconnected end at the helm, make sure its at least twice length of boat then pull through, then reconnect what youve just pulled out and attach two wires for connecting to bilge pump and pull all back through. yes its a pain but it is do-able.
