Easy install. Works great

Good

I installed and it worked great. My only complaint is that it tests itself every couple of minutes and makes a sound. I have a light on my panel that flashes a bright red light when a pump comes on. The pump was installed in a sleeping area and I had to remove it because the noise and the bright warning light on my system annoyed me to the point that I could not sleep. I replaced it with a Rule float switch model which are great. Only brand I use.

Working fine

Bought this product several years ago and waited to see how it performed. Still working as designed and very reliable. Over five years now and still going strong.

I replaced an original automatic style Rule Model 27S that failed after 7 years with this newer model 27SA. I purchased this one in hopes that my original snap-in base would fit on the new model but unfortunately that is not the case. The pump housings themselves are different and incompatible. The good news is that although the outlet hose is offset from the original, the new model has slotted screw holes so that the original mounting screws can be used and the unit can be rotated to align with your existing installation. That feature is a nice touch that I appreciated even more while in an awkward position lying down to access the bottom of my boat.

Just bought and installed this product. The 2.5min timer turns pump on for a second, but does not consistently pump out water when immersed. The auto sensor does not work reliably. Going to return it.
