HYDROPUMP DH900 and DH1800 each comes complete with its own mounting bracket that makes it possible to set the pump easily at the desired height in the sump according to your main pump position and the water level. The pump typically stays above the water line, but you may need to mount it in a position where it does get partially wet each time the main sump pump operates. This gives it a better "pump-down" when it does need to operate. Its job is to keep the floor dry until the problem with your main sump pump is resolved. The included stainless steel bracket hangs the pump against the wall of the sump, out of the way and at the desired height. If your sump is of standard size, say 15" - 20" across at floor level and 18 - 30" deep, one of the DH models will most likely fit just fine with your existing primary sump pump.

 

The ease of installation of the DH900 and DH1800 cannot be over-emphasized. The fully assembled compression tee assembly shown to the right, means no guesswork and NO GLUING!  Using this connection system and the Stainless Steel mounting system, we dare say this is a backup sump pump that can be installed in a typical sump in less than an hour!

Space in the sump at a premium? You may want a vertical float switch instead of our standard tether float to avoid conflicts and congestion in the sump. You can order either DH900-VS or DH1800-VS on our ordering page for only $15.00 extra. We replace the standard tether float with the vertical float.
The fully adjustable vertical float with its slim design and built-in clamp is easy to mount on the pipe from your primary sump pump. Click the photo to enlarge>>>
