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).

Typical Installation of
Hydropump  DH900 & DH1800

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. 

Standard Installation:

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 compression Tee fitting assembly to main pump discharge pipe and clamp hose to barbed fitting.

6. Float comes clamped to pump, but you may remove it and use smaller hose clamp (included) to attach it to discharge pipe and adjust cord for proper swing of float.

7. Connect the battery and test the unit! See instructions for details on startup procedures.

Hydropump RH1400

Hydropump RH1400

With only the suction pipe and float in the sump, it fits in very narrow sumps. You must have a 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 requires setting the float at the proper operating level to keep foot valve underwater when either the main pump OR Hydropump runs. If the main pump runs while the foot valve is exposed to the air, it will allow air in to break the prime in the Hydropump. If the sump goes down below the foot valve on its own, and not from being pumped out, this does not apply.

Standard Installation:

1. Place unit on floor next to sump.

2. Unplug main pump.

3. Install suction pipe with check valve and suction screen. and adjust to reach near the bottom of the sump. Cement parts together only when you're certain of final position. 

4. Insert tee assembly into main pump discharge pipe above your existing check valve. Cement into place when you are certain of its final position.

5. Connect discharge hose to barbed fittings and secure with hose clamps provided.

6. Mount and float switch to suction pipe using attached clamp and adjust so pump operates only when main pump fails.

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.

Typical Installation of
Hydropump PH3000

Hydropump PH3000

This is a very simple project for a Saturday morning. After attaching the float and a few discharge parts to the pump, you are ready to place the pump in the sump and make the final hookups. Typically, this would take less than an hour. Refer to drawings in the installation manual for specific instructions, but here is a brief breakdown of the procedure.

Standard Installation:

1. Connect discharge pipe, check valve, and hose to PH3000 Pump.

2. Attach float switch to the PVC pipe using the included stainless steel clamp.

3. Lower pump into the sump and place next to main sump pump, as shown.

4. Use hose to determine location on main sump pump discharge pipe, cut out short section of pipe to receive tee assembly, and glue into place. Tighten fittings and clamp the top end of hose to tee assembly.

5. Mount water alarm on wall and attach sensor to pipe in desired location using cable tie and clear tubing around sensor wire.

6. Mount inverter on wall within cable reach of battery case. Make sure power switch is in "Off" position.

7. Place battery into case, connect cables to battery,  plug in float/pump to inverter and charger to wall outlet.

Charger will start automatically. Turn on inverter and test pump. Even a new battery may need charging, so it may take a day or two before full operation is possible. See instructions for details on startup procedures.
