Rule automatic bilge pumps have an internal computer chip to cycle pumps every 2-1/2 minutes. The pump runs for one second and shuts down if no water is detected. If water is detected, automatic pumps sense resistance at the impeller and run until water is removed. No float switches required.
500 (Rule 25SA), 1100 (27SA), 1500 (51S), and 2000 (53S) GPH pumps handle the spray and rainwater that can quickly fill a small or open boat. 12 volt DC. Minimal power use or current draw in sensing mode. All pumps are completely submersible, rust and corrosion free, and ignition protected. Built in strainer base snaps off for easy cleaning.

Can I install a float to prevent the battery from running down? My boat is not operated for 3-4 weeks at a time
You could, but it won't run until the float switch activates and the pump senses water.

Can you wire the pump such that you can force it too run in a manual mode just like the typical float switch?
Yes I can flip it on where it will bilge water.
With an automatic float switch I would think not without manipulating the internal float switch, which I personally would not recommend, however, if you bought a non automatic, then yes you could run on a manual mode by using a normal relay switch instead of an external float switch.
Yes you can. It is a 3-wire pump. But I can tell you that if the pump is stressed, and runs empty, it heats up the electronics and fails. To date, Rule has replaced the pumps we have had that failed with an argument. We had customers who had pump failures during recent hurricanes.

Yes the Rule 25s has 3 wires one for auto and one for manual. I use a Seachoice bilge pump fused toggle.
Should I install a hose check valve with a rule pump?
Depends on the length. Over six feet, maybe.
Not really necessary if you make an upright loop in the hose so that water doesn't come in through the bilge pump hose.
I did on my J-105 and it works well. Keeps water from running back down into the sump and turning on the auto switch multiple times.
I do not know the answer to that question. Sorry.
If the pump runs all the time how do you stop it?
It kickes off and on as long as it has power to it. I hooked mine up on a switch and turn it on when Im using the boat and off when not using the boat. Theres another wire that bypasses the float switch which I didn't hook up
It doesn't run all the time. Cyles
1100 rule pump it will not shut off at all.?
If it runs all the time, you have a huge leak in our boat.... if not, the float switch is in the wrong position. I never replace my original pump... this models hose fitting was too small. I do remember reading that there were 2 setting. I'd contact Rule or search the web for a printable pdf file of working instructions
When I come off the water, I separate the fuse in the line so the power is shut down.Wish they would come up with cut off switch to make it easier.
J-While your pump doesn't actually run all the time, it will continue to "sample" every 2 minutes or so. Your options are ;1. Wire in an on/off switch somewhere; console, dash or wherever2. you will manually remove a lead from your power supply.

It stops automatically when it senses that there is no more water. It works flawlessly as long as your battery is good.
I have a 500, 2 years of very light use. Now pump runs constantly, no shut down & battery runs down. Is there a recommended fix or should I replace the unit?ThanksCB
You may try taking the cover off the base and see it there is gunk stuck in the screen. I clean mine out every once in a while. Other wise replace it.
I did not install an on/off switch. Pump only runs to check for water. Have not had any problems.
HelloYou can try to clean the pump by running in soapy water and see if that helps; otherwise replace the pump.Ed
My pump has an in line fuse. I simply "unplug" it when I am done for the day, and plug it back in on the next trip. No extra battery use.
How do you secure this pump to the bildge?
I secured the pump to hull inside my engine compartment with a marine grade adhesive. This pump works great. -Steve
The blue plastic piece on the bottom comes off easily with two side clips. The blue piece has 4 screw holes so that you can secure it to the bilge. I have used small wide screws. There is also a screen that sits inside the blue peice to prevent debris from getting into the pump.Then you just slide the white bilge pump into its clips.
The bilge pump has a strainer attached to the pump (colored blue in the photo) which detaches. There are two screw holes in the bottom of the strainer which allow for the attachment of the pump to the bilge.
Can I leave this pump on my swimming pool cover during the off season so it will automatically remove rain water?
Yes it will but you can't permit the pump to freeze. You also have to keep the plug on the cord out of any water or it will short. The automatic functiomn on these pumps is very sensitive and cannot handle power surges, etc.Hope that helps.
J L FULLER
Will work fine as long as the water doesn't freeze.
pump if fully automatic. I would think you could leave on swimming pool cover. Its 12 volt so you would need to hook to battery or transformer.
Will the pump activate at less than 3 inches of water?
I don't know, but I believe the specs that come with pump can tell you that. Good luck
yes, but not much less than that. Mine runs in a little less than 2 inches
Mine activates with about 2 inches, but that's about the backwash from the hose line. My pump is the 2000 that automatically samples the water level every few minutes. It's been in service for a year and so far so good, however I have a very tight boat.
I installed mine and found the automatic feature didn't work. Since this was one of three bilge pumps in my boat, I didn't bother to pull it back out. Because of this, I have no idea how much standing water will be there in automatic mode.
Yes it will if you mount it flat with the hull. In my boat there is a slight V at the bottom so I placed it on a flat piece of marine plywood that I epoxied in place so it will not start pumping until the water is about 1.5 inches deep. These really are excellent pumps. Installed both of mine over two years ago and they work flawlessly.
yes, down to about 1/2"
which pump would work best in a crossbase?
I have two RULE pumps in my boat, They are a quality product. However this is the first automatic bilge pump that I purchased and as of yet I have not installed it.
Sorry, don't know what a crossbase is.
What's the head limit on the 500gph unit? Ten feet? More? Less?
Well, in a 12v system at 3.35 feet it will pump [310gph]; at 6.7 feet it will pump [180gph], I wouldn't recommend going another further than that, if it's a vertical hose set-up to reach the thru-hull instead of let's say a 20-30 degree angle from the pump location then you shouldn't be going over 3-4 feet for a little 500gph pump. In general, for a 10ft set-up I would purchase the "RUL-27s" 1100gph or larger, thank you.
Purchased this pump last season. I have a small boat 25' every 2 1/2 minuets you hear the pump cycle on. Try setting your sleep cycle to this pump. It does not always turn itself off. When we launched the boat this year it ran my cranking battery down to nothing. I have cleaned it several times but it continues to run after cycling.This pump is located in the aft bilge and not very accessible which adds to my frustration. I paid about $175 for this pump and am changing it to a non automatic wihth a separate float switch (Water Witch electronic).
Piece of junk
After taking great care to ensure the correct installation of this product and sealing all electrical connections last May, the 2 1/2 minute automatic timer failed after about 2 months. So we used the unit manually. This fall I left the pump in the boat while occasionally charging the batteries so that I could quickly bilge rain water. It died in December. What a pathetic piece of junk.
Will never buy another one
I bought this to replace my float switch pump. I am very unhappy with the product. Sounds like someone is constantly tapping on the hull of my boat
Fail On / Fail Off
Replaced similar pump with a float switch. Solved the problem of the pump running dry when heeled on a tack. Go a few hundred miles... pump fails. New problem is 3 failures of the fully automatic pump. Fails off 2X. Fails on 1X. I installed a parallel larger pump for several reasons, but I still would like this pump to work as primary, low flow, bilge pump. Last failure (Failed ON) was three weeks after install.
Boat Bilge...mainly for raineater build-up.
I recently installed this pump in the back of a small outboard-powered skiff. I chose it over float-switch operated pumps because I didn't have much room. Also, looking at internet ratings, these automatic pumps seemed to be consistently higher rated than similar pumps with float switches, leading me to surmise that float switches are more problematic. This pump has 3 wires, so it can be wired to come on continuously, or for the characteristic on every 2 1/2 minutes to "test" for water. I only wired the intermittent circuit, although I see myself wiring continuous mode in the future to force it to run, for example during clean-out of the boat after use. The pump works very well. The slight noise when it cycles on is noticeable, but not objectionable. I will only occasionally use it to keep the boat pumped out while unattended. I have not yet used it long enough to judge long-term reliability.
This is a GREAT pump. I bought two to replace older and much larger pumps with external float switches. Since this one cycles, and detects water, it is trouble free.I have a leaking outdrive boot, and a stream of water is leaking in. This pump not only keeps up, but cycles off when it catches up.Yes, I do plan to replace the leaking boot next week.
Keeps on Running
I liked this pump until I found it running none stop with no water in the bildge, Paid over $70 for the pump this spring, about 90 days ago. Waiting to see how the marine store is going to back up my purchase with no receipt.

These pumps are the best idea ever! Forget broken and/or unreliable float switches. The pump cycles regularly (and you get used to the quiet sound), staying on only if it detects resistance - water. The other review here is a small boat, obviously, with no charger. Pump uses only a very small amount of amps, and if you're hooked to shorepower it's a no-brainer. I LOVE these pumps! So will you.
Works fine for me.
I have used a RULE automatic bilge pump for years. I have owned several of these and have had no problems such as Fred describes. The pump cycles periodicly to sample for water and than shuts down. In doing so, it uses very little current.I find this much more reliable than a float switch, which is prone to hanging up.The only thing I can think of is that Fred had a small leak, causing the pump to constantly be pumping out his bilge, leading to a dead battery.
