John, this is not an Ultra switch, it is an aqualarm knock off. Rodger showed me an Ultra and this looked pretty wimpy. If it only did it's dance for a little while during the back wash, I could understand that (although the simple Rules I have elsewhere are immune to this) so I still don't get why bouting it any higher will change things.

Subject: Beware: Aqualarm "Heavy Duty" Bilge Pump Switch
George -
It isn't the switch's fault. That's an Ultra Pump switch and I have several. A fine piece of gear, IMO.
Because you are using a centrifugal pump, some of the water drains back when it stops and actuates the switch. If you can't baffle the area where the switch resides to stop short-cycling, raise the switch and live with a bit more water in the bilge. Or, if this is simply keeping a small space "dry" and not a primary bilge pump, use a small pump (loke a Rule 360 or 500) with small hose which will result in less drain-back.
If you want a really dry bilge you'll have to install a positive-displacement pump.
The best bilge pump switch, I think, is a home-made equal to the Jabsco Hydro-Air switch, P/N 59400-0012. Use an adjustable diaphragm switch mounted high and a piece of clear vinyl tube to reach to the bottom of the bilge. The best of these will have an adjustment that will allow on and off settings in the 1-4" range.

"Seahorse"
With the very able help from listee Rodger Wrona, had one of these (Model 20090) installed in my least accessible bilge to replace a worn out Rule which in turn had burned out a Rule pump. Rodger rightly looked askance at this product from the get-go; here I was thinking I had a premium product.
For one thing, this is only set up to be mounted to a bulkhead or stringer, none being readily available, Rodger cannibalize a bracket from an Ultra he had around (wrong voltage for me, so my next purchase).
Well the gist of this rant is the darn thing won't turn all the way off. Once the bilge is drained it rapidly switches on off three beats at a time. This will mean bye bye bilge pump before long, not to mention it is right under the Wife's pillow...
So I beseech Aqualarm for help. The answer I get is that the "sensitivity cannot be adjusted. Can you mount it higher so that it won't cycle as much?" To which I reply," how will that change anything...it doesn't know how deep the water is below it does it? Won't it do the same GD thing only with a higher amount of bilge water below it?" To which they have no answer. So now I gotta manually drain this bilge religiously (at least until the rudder packing is re-done, they are tightened as far as they can go) until I can get somewhere up the road and replace it Had to head on out of Brunswick, and of course it is the weekend regardless.
Are Rodger and I missing something or is this (and Aqualarm Inc) the piece of ----- I think it is? I was going to spring for their water flow sensors, but can't take that risk after this experience
Please someone tell us we are missing somethng! The vendor already has assigned us kite flying duties.
