Hydropump Model RH1400 Battery Backup Sump Pump with NEW Battery Watch System

One Pump, Two Installation Options:

Inside the Sump OR Outside the Sump

This battery backup sump pump is the most unique pump on the market today. Never before has a pump been designed to be installed either Inside the Sump or Outside the Sump, depending on the situation. If you have a standard size sump, no problem, this is the backup pump for you.

However, there are times when the typical backup pump just will not fit your sump. You may have a very small sump with no room for another pump in there. It's not going to happen! What to do?

Enter the Hydropump RH1400 that can sit on the floor, outside the sump. And not only that, but you may think your sump is too small, but in reality, it may be larger than you think. The new, improved Model RH1400 gives you the ability to change your mind right up to the time you install it, whether to mount it Inside the Sump or Outside the Sump.

The Battery Watch system.

Before we show you the installation possibilities, we want to introduce our newest feature.Mounted right on the cover of the battery case, there is a display readout that indicates the voltage of the battery. This removes much of the guesswork when it comes to battery life. The simple directions for using the Battery Watch are right there on the cover as well.

Simply unplug the charger from the wall outlet, wait an hour, and go back and read the numbers on the display. Above 12.5 Volts, all is well. Below 12.5 Volts, time to get the battery checked and possibly start looking to replace it. Simple, straightforward, and clear.
