Hydropump Installation Instructions

Depicted below are sketches of typical installations showing each Model and the steps in the process. For each, the process is basically "plug and play." Complete instructions are included with your new Hydropump as are all the colored parts shown in the drawing with solid outlines. Our design team has tried very hard to think of everything, and the only thing missing, besides the battery, would be an item for a very unusual situation.

Tools and Supplies Needed: Utility Knife, Hand saw or PVC Cutter, Pair of large adjustable Pliers, Slotted Screwdriver, PVC Cleaner and Cement (small can of each).

Hydropump DH900 and DH1800  

These are about the easiest backup sump pumps to install on the market today. They both install the same way using the same brackets, etc. The only difference is the size and pumping capacity of the two pumps. Using an adjustable mounting bracket and standard PVC connections, very few tools or supplies are needed. Be sure the check valve on your main pump discharge pipe is in good working order or replace it. Take note that the connection point on the main pump discharge pipe is much higher for the DH900 (Step 5) than the DH1800. We include the extra hose length needed for this purpose.

 

 

Standard Installation Steps:

  1. Put 2 parts of stainless steel bracket together.

  2. Connect hose to pump with hose clamp.

  3. Lower pump/bracket assembly into sump against side wall.

  4. Place battery case with battery onto bracket resting flat on the floor to stabilize pump.

  5. Unplug main pump, drain water out, and connect Tee fitting to main pump discharge pipe and clamp hose to barbed fitting.

  6. Attach float EITHER to pump bracket OR to discharge pipe using one of the 2 clamps provided, and adjust cord for proper swing of float.

  7. Connect the battery and test the unit!

 That's all there is to it! See instructions for details.

Hydropump RH 1400

With only the suction pipe and float in the sump, very narrow sumps can accommodate it. You must have a good quality, fully functioning, one-way check valve in the discharge pipe from your main pump, as shown, to prevent water from returning through the main pump and into the sump pit. A one-way foot valve at the base of the Hydropump suction pipe prevents water from returning to sump pit through Hydropump and keeps Hydropump primed. This installation does require setting the float at the proper operating level to keep foot valve underwater at all times, even when the main pump OR Hydropump runs. If the main pump runs while the foot valve is exposed to the air, it may allow air in to break the prime in the Hydropump. If the sump empties below the foot valve on its own, and not from being pumped out, this does not apply because the water has to rise above it before either pump runs again.

Standard Installation Steps:

  1. Place unit on floor next to sump.

  2. Unplug main pump.

  3. Install suction pipe.

  4. Install discharge hose and fittings.

  5. Mount and adjust float switch. 

Run main pump by lifting it's float with water in the sump. This primes the Hydropump.
Connect battery and test the Hydropump unit. See instructions for details on startup procedures.
