Comments about Johnson Pumps Johnson Ultima Combo Pump - 500 GPH Open Flow:
After two good seasons, the water sensor failed. The pump works great but my boat docks in deep water an hour's drive from my home; operating without an automatic pump is out of the question. Now I need a new sensor but they don't sell that part by itself.
Pros
- Pump works fine
Cons
- Ineffective
Best Uses
Comments about Johnson Pumps Johnson Ultima Combo Pump - 500 GPH Open Flow:
The pump itself works fine and I like the replaceable cartridge feature. Unfortunately, the "field effect" auto water sensing feature doesn't, at least not after two seasons. The sensor is not available as a stand-alone item, so I guess I have to buy a float switch from someone else.
Pros
Cons
- Not Durable

Comments about Johnson Pumps Johnson Ultima Combo Pump - 500 GPH Open Flow:
The Ultima bilge pump switch would be a good product, if it lasted longer. Mine lasted slightly more than one year, causing damage to my flooring in my boat. After reading on-line reviews at various web sites, I purchased a Waterwitch electronic float switch, which has a 7 year warranty and is used by the Coast Guard. I suggest that you do your research before buying this switch.
