Whale Supersub 650 Bilge Pump ?

[endoftheroad]

I am considering purchasing this pump but can not find any comments or reviews here or on the web.

Any comments?

Thanks

We have one under the engine. The idea being that if an engine hose goes the auto version will pump water into the cockpit and warn me something is wrong if I am sailing solo topside.

I've installed it over a year ago, and the only work it has had to do is me switching it on manually, or dunking it in a bucket of water once in a while, to test both auto and manual functions. Works everytime. Was easy to install, and the rotating head and port is a treat, specially that I had to have the exhaust hose go sideways first, and then out. Am sure you've looked at their catalog but if not, double check the minimum dimensions required to see if it applies to where you want to put it in. Hope this helps.

good plan!

Whale makes great products.

Why is it that there arent reviews for this pump to be found?
There isn't even much on this forum to be found yet I have found many distributers that sell the pump.

I tried to use a SuperSub 650 as a sump pump, but it didn't work well. It would sometimes run, run, run without moving any water. I suspected some kind of airlock. Turning it off and back on would sometimes help, or reaching down and giving the pump a jiggle. Ultimately it allowed the sump to overflow several times and I got tired of dealing with it. I replaced it with a diaphragm pump and haven't had to worry about it since. Quieter too.

I installed one earlier in the year to replace a fried little Rule unit. It works well and the price was right. I use it to slurp up water in my aft bilge, which is flat. This type of pump is the only thing that will fit.

Be aware it won't get the last inch of water and the "fall back" can be a cup or two if the hose is going into the sink or something.

"electric field sensor tecnology"?

Does that draw from the battery?

I cant understand why there is so very few reviews for this pump online.

DIY Boat Owner magazine Review: Whale Supersub Smart 650

“... During 500 test cycles at a lift height of 4.5 feet, the pump drew just 3.3 amps at 13.1 volts, emptying all but the last ¾ inch of liquid in the bilge. It also worked well on a low battery. And so, it garnered an eight on our DIY Rating System.

However, we observed no resistance to backflow and recommend considering backflow protection in each installation.

PROS: Amazing capacity and ultrasonic water sensor/switch at just 0.71 pounds and 3.3 amps.

CONS: We wish it included integrated backflow protection...”

Why isn't there any info to be found anywhere concerning the draw, if any, on the battery due to the "electric field sensor tecnology"?

Okay, so I got the pump.
I also bought some 16 gauge 3 wire.
I have 2 new 12 volt batteries (starting and house).

I was told that I can wire my Whale pump to both batteries.
Is that true?

Thanks

You can wire it to as many 12v batteries as you wish. What are you trying to accomplish? If for some reason it fails to shut off, it will drain every supply its connected to, eventually.

I would like my pump to have as many pumping minutes as possible.
I have 2 new batteries.

Using my 16 ga 3 wire, do I simply connect a wire to each positives of my batteries and then the negative to one battery (as the negatives are connected together)?

Thanks

16 gauge is a little small if the cable run has any length, just hook to pos/neg and make sure to put an inline fuse as close to the battery take off as possible
