Most people realize they need a back-up sump pump a day too late – after the basement has flooded due of a power outage or sump pump failure. Then, they find out that home insurance does not cover flood damages to the finished basement (say $20,000). Nor does it cover mold remediation (say $12,000), should that become necessary. So, they pick up a pump in a store but nobody warns them that:

• it has less pumping capacity than the primary pump although it will be called on during the year's worst storms.
• it has a lower reliability than the not-so-reliable primary pump it is supposed to back up.
• it may interfere with the primary pump float or the check valve, causing basement flooding.
• its short useful life is only 2–5 years before it needs replacing.

What makes our battery-powered sump pumps so unique?

Location, location, location! That's also key to the reliability of back-up sump pumps. Unlike other pumps, our pumps and their floats are placed out of the sump water. (See RH-1400 illustration.)

Keeping the backup pumps and floats out of the water avoids continuous exposure to dirty water, mud, and debris. No clogging, mineral deposits, corrosion, or deterioration means maximum reliability and longevity of the backup system.

Our back-up sump pumps do not interfere with the primary pump or its float. Most residential sump pits are just too small for two pumps. Installing a second pump inside a small pit makes it likely that the primary or secondary pump floats will get stuck or even entangled, preventing both pumps from operating.

For maximum reliability, our pumps feature a slim-line vertical float switch instead of a tethered float. This practically eliminates the risk of a stuck float inside a busy sump pit.

The discharge pipe connects to the main discharge pipe high above the primary check valve (2-4 feet). Other backup pumps are placed inside the pit above the main pump. Consequently, the primary check valve is just inches above the main pump, where it is exposed to strong turbulence and constant pressure fluctuations. Such a stressed check valve tends to break or develop a hole. Once that happens, the back-up sump pump will just recycle water through the primary pump down into the sump pit and flood the basement.

The suction pipe of RH-1400 and PH-3500 back-up pumps reaches to the bottom of the sump pit, so that it can fully empty the pit in each cycle. Other back-up sump pumps are installed above the main pump and do not have a suction pipe. They drain the pit only partially, resulting in short pumping cycles, frequent starts, and a shorter service life.

Unbeatable pump performance

The lift ("head") is the vertical distance from the bottom of the suction pipe to the highest point of the main discharge pipe. The higher the lift, the lower the pumping rate – however, it does not drop dramatically until about a 15-ft. lift.

The Residential Pumps RH-1400 and DH-1800 are powered by a heavy-duty, high-efficiency DC motor (submersible). The Professional Pump PH-3500 has a powerful 120 V submersible AC motor and a power inverter for converting the direct current from the batteries to alternating current. (If ever needed, you can bypass the batteries with the inverter and plug the pump directly into 120 V AC.) View a photo of PH-3500 and the layout of PH-3500. For more technical information on both pumps, check out Backup Sump Pump Specifications (PDF).

Each pump kit includes a high-impact battery case to protect the battery and terminals. An automatic finish charger keeps the battery fully charged and also maintains a steady Voltage (unlike a trickle charger). The standard PH-3500 kit comes with 2 battery cases. To double the pumping time of residential models, you can purchase an extra battery case with a set of interconnecting cables for a dual-battery set-up.

About back-up sump pump DH-1800

This is the same pump as RH-1400 which it is placed inside the sump. There is no suction pipe and it delivers a higher pumping rate but at a lower price.

For maximum reliability and longevity, the pump and its float are placed high and dry well above the normal high water level inside the sump. The pump hangs on a very unique stainless steel L-bracket and its height is fully adjustable.

The vertical float switch is clamped on the pump. For minimum interference, the pump with its float has a small footprint inside the pump – 8" deep from the wall, 9" wide and 10" high. It is suitable for tight sump pits.

Of all the backup pumps on the market, this is the easiest pump to install! You should be done within half an hour

The complete pump kit makes it easy

RH-1400 kit

DH-1800 kit

PH-3500 kit

All accessories for a typical installation, except batteries, are included. Each RH-1400 and PH-3500 pump kit includes:

• Powerful pump and motor
• High-impact plastic battery case with cables (2 cases for PH-3500), battery status lights
• Finish battery charger, pre-wired (and a power inverter for PH-3500)
• PVC suction pipe with one-way foot valve (check valve) and stainless steel screen
• Vertical float switch and clamp
• 1-1/2" Wye connector for inserting into the main discharge pipe, 1-1/4" adaptors included
• Flexible discharge hose and clamps
• PVC fittings for a typical installation
• Integrated buzzer alarm to let you know the primary pump needs attention
• Illustrated installation and maintenance instructions

Easy do-it-yourself installation

Make sure there is a good-quality, fully functioning main check valve well above the primary pump but below the backup discharge connection.

The pump installation is a breeze! Tools and supplies needed – a PVC cutting tool or hand saw, PVC primer/cleaner and cement, Phillips and slotted screwdriver, utility knife, tape measure, large adjustable pliers.

1. Place pump in position on the floor
2. Install “Wye” connector on the main discharge pipe and connect with a flexible discharge hose
3. Install suction pipe (not on DH-1800)
4. Mount float switch and alarm
5. Install battery and plug in.

If there is a sump pump cover, you have to drill a hole for the backup pump discharge hose.

You have to purchase locally a 12-Volt Marine Deep-Cycle Battery size 27. Unlike car batteries, deep-cycle batteries have thicker plates to allow repeated complete discharging. Ask about the best battery quality and warranty. A GFCI outlet is needed nearby to plug in the unit.

The included PVC suction piping includes a 1-ft. section for the horizontal distance from the pit, an elbow, and a 2-ft. section for insertion into the pit. The piping can be cut as needed or substituted with longer piping, providing the suction height does not exceed 4 ft. Make sure that the end of the suction pipe remains submerged after the primary pumps empties the pit, so that the backup pump does not loose its prime.

About the pump operation

Widely adjustable float: The vertical float can clamped at any height on the main discharge pipe and the float travel is also widely adjustable (about 9 to 3 inches). Whenever the water level in the sump pit rises too high, the float reaches a switch at the top of the float rod and activates the backup pump. The pump will shut off when the float fully returns to the normal down position – the bottom stopper (the Off switch). The placement of both switches is easily adjustable up or down.

The high water level in the sump should not reach the drainage tiles. Filling the tiles and gravel bed underneath the slab would greatly extend each pumping cycle and if not sealed with RadonSeal, the concrete slab would wick in water.

The bottom foot valve holds water inside the pipe and the pump, which keeps it primed. During a dry season, the water may evaporate but afterwards, the first run of the primary pump will refill the backup piping again through the Y-connection.

Inspect regularly the main check valve to ensure it is in good order. Its failure could cause the basement to flood.

The installed pump must be protected against freezing.
