SEAFLO 03 Series Max 25A Bilge Pump Float Switch - 12V/24V Automatic Water Level Controller, No Filter Housing, 14 AWG 1m Wire for Marine Boat Pumps, SFBS-25-03A, 4-Year Warranty

Bueno

It’s a flapper. Low profile. Works good.

After a little over a year from installation, this switch still works well. I also purchased a SeaChoice model about the same time that has already failed. This has been the best level switch I've used in several years, including the "Rule" model. I have become frustrated with buying new switches every 6-12 months due to horrible quality. This one seems to be among the better ones but would still rather have a real old-time mercury-wetted, tried and true, type.

Works like a champ. Prior to this one, I've had two other different brands of bilge switches quickly fail after only a month. This one has been going for over four months with no issues. That is very appreciated given I have a deep bilge and it is a PITA to pull the pump/switch assembly out for repair/replacement.

Good Quality Built Float Switch for my Sailboat , can register it with SEAFLO to double warranty , I like that !

I installed this switch yesterday and was annoyed that the weight of the float is not quite enough to depress the switch. It would just stay up after the water was gone and the pump would keep running. After 4 or 5 buckets of water it seemed to work okay. The build quality is pretty good otherwise. UPDATE: 1 month later and the switch is not working and seems to be jammed. Found the boat full of water and the battery dead. Total junk. I think the shaft is normal steel as well as it is rusting!

Very sturdy plastic construction with clear installation instructions. The float and the base come apart to make installation of the base on a weighted or stable surface much easier. This was one of the less expensive options I was able to find, but it has worked flawlessly and held up to a harsh outdoor environment with no problems. I don't use it as a bilge pump, I use it in my garden to stop the fountain pumps if the water runs low and it does that job perfectly.

Replaced arm type, kept sticking in off. Used to make bilge pump automatic on boat. Also wired strobe alarm light on console, if bilge turns on I have audible and visual notifications. Very pleased with operation and installation instructions

Original RULE switch (fairly new) would occasionally not "start" unless given some wave action, and needed a larger swing area under engine block. Heavy rain and calm marina was a recipe for disaster. After checking on boat and finding it didn't engage (starter almost under water on new 5L merc.) I installed this this one. 3 days of rain and every day I check it, it has done it's job more efficiently than RULE brand. Cheeper than a $25K engine replacement.
