I pumped out some summer rain water as well and that got me to reflect on how to get rid of winter rain accumulation this year. Well my friend last night started the reflection when demonstrating his set up for pumping water between water butts in his green house.
He has bought a little whaler orca 500 pump which he is attaching to a Yuasa 12v 12 amp dry cell battery which he is storing in a cheap food storage Tupperware tub. It's water tight when clipped down. He will drill a hole for the wires to exit through a waterproof seal/gland. He will wire up a fuse and a switch and then use a solar panel trickle charger to keep the battery recharged up. It's a clever set up. Details about this little pump can be found here. At the moment various chandlers have them on line for around £14. Good value and they are submersible as well!
I have thought about bilge pumps before. I have often looked at a whaler urchin hand pump but where to mount it? It needs to be somewhere in the aft cockpit and then tubes would need to be drilled through the centre thwart lockers and......well the pump would get I the way even if it was mounted flush in the thwart and too much drilling through bulkheads. The advantage of the orca is its simplicity and minimum drilling required. The battery could be stored in a watertight locker and only a small hole and waterproof seal would be required for wires to exit. The pump could be attached to. Piece of 3mm ply and basically be moveable. As long as the exit tube rises upwards and can form a u bend on the inside of the hull before exiting via a waterproof seal in he sheer plank...which it can....then all is hunky dory so to speak.
I need to investigate it more but for the price of a whaler urchin I could get a simpler more versatile system and if I installed a float switch them over winter it would automatically pump out water. However, for simplicity sake I'm just thinking some wiring and I just connect it up periodically to pump out once a week the rainwater collection.
I'll give it some more thought but my initial thinking is its useful. During sailing it could be also used when its raining to pump out water that collects in floor well as as well!
