Re: Bilges - On vs. Automatic; Capacity?
My main bilge pump was wired to run automatically without going through my panel. It was also wired to be manually controlled. I'd recommend this arrangement, rather than just setting it up to only only automatically.
Why? Because your automatic switch might fail. I had a brand new Jabsco pneumatic switch fail the first time it was called to duty during a freak event associated with a 3 day-long Northeaster. It didn't sink the boat, but it did float my floorboards before I went to check on the boat. What if it were a more serious situation? Assuming you were on scene, you'd want to have another option to turn the bilge pump on. I do have a manual pump installed but that is only for extreme backup.
BTW, I never got a response from Jabsco on a warranty claim, not that would I trust their Chinese-made switch again. I replaced it with a Johnson Ultima switch that can be easily tested.
