      They fail, buy the extended warranty

            Comments about Rule Industries Automatic 12V Bilge Pumps:

            I have used these pumps for over 20 years. I have a second large pump in case I get a big leak and use this to keep the sump almost dry. They last a couple of years and then fail. The first one I bought had a lifetime warranty but it turns out you only get the terms of the warranty when you try and collect, not the terms in force when you buy. Last time I bought the extended warranty and will try and collect on that tomorrow. If I have to buy another one, I am looking for another solution

                  This bilge pump is set up to go through a switch which is not what I wanted, and certainly inappropriate for a bilge pump. I had to try to seal up the wire for the switch - hopefully water in my wet bilge will not get into the wire!

                              I have bought half a dozen of these, they USED to be great. After so many repeted failures, (2 right out of the box), I finally called ITT and complained. They said they had just moved their facility to Mexico and had not noticed any problems yet. They mailed me 6 free units to appologize. One year later all 5 were dead. I have to leave for the holidays and Was going to install the 6th in my boat, some slight tugging on the wires to straiten them out from packaging was all it took to crack the red housing at the top of the pump body.

                              Every unit has failed differently... some the electronics stop checking for water and the manual circuity works, others the automatic circuity stays on and burns the motor up (fails to turn off), some fill with water in the "sealed" part and some just stop working all together.

                              I dont think there is another single person who has bought sooooo many of these units over the last 10 years and used them consistently...

                              ...and its with the utmost of certainly that I will never buy one again AND I WOULD WARN ANYONE WHO VALUES THE SAFELY OF THEIR BOAT NOT TO BUY ANY RULE PRODUCTS MADE IN THEIR MEXICO FACTORY BECAUSE OF EXTREME POOR QUALITY STANDARDS!!!

                                I bought this pump as a second bilge pump because of the auto sensor / no float switch feature. It worked fine - came on every 2.5 minutes for the first 2 months, but now it will only work in manual mode.

                                    Like many others I wanted an auto bilge pump. Like many others this pump failed after only two year as the switch is broken and won't turn off.

                                      Comments about Automatic 12V Bilge Pumps:

                                      I installed this pump as a 12 volt back up for my basement 120 volt sump pump. After the power went out, this pump ran for 14 hours straight with no problem keeping the water out of my basement during hurricane Irene. It kept up. I powered it with a 27 frame deep cycle boat battery and got no water when my neighbors all took on between 4 and 8 inches. None had a back up. I will get an 1100 to insure it has the capacity during the worst conditions and keep the 500 as a back up to the back up.

                                          I wish it would cycle like every 15 minuts instead of 2.5. it would be great as a shower sump pump that you only turn on wile taking a shower, but as a bilge pump it cycles too often and draws almost 2 amps for 1-2 seconds every 2.5 minuts. I'm going to add a float switch, but it would be great if the timing was adjustable. it would be better every 15 minuts or every half hour. for my install, I would like it at 1 hour intervals.
