#1 – WAYNE ESP25 Review: The Best Battery Powered Backup Sump Pump.The Wayne ESP25 comes from Wayne, a Scott Fetzer Company. Wayne Pumps have a sterling reputation among professional plumbers.
Its size of 7.2x5x10 inches is similar to a primary pump, only narrower. The housing is cylindrical and solid with no external projections that can be damaged due to impact with the primary pump or the sides of the sump.
The Wayne ESP25 has a pumping capacity of 3300 gallons per hour (GPH) at 0-feet, 2300GPH at a 10-feet lift, 1500GPH at a 15 feet lift and a maximum lift of 20 feet. This is enough for most home based usage. The outlet pipe is 1½ inches in diameter which is compatible with most commercial PVC pipes.
It uses a magnetic reed style float switch which opens and closes as the water level changes. This is one of the more reliable switches in the market today.
It has a very simple battery display, with a light indicator showing green, yellow and red for the level of battery. This can also be seen in the dark which is useful in case of power failure.
It has a sound based alarm, which warns you when the backup sump has been activated.
It uses single 75 Ampere, 12 Volt deep cycle batteries and no additional battery can be placed in serial.
The sump pump is made of reinforced thermoplastic which is corrosion resistant and unlike cast iron products does not require additional epoxy based coating which need to be periodically renewed over a period of time. It can be picked up using a stainless steel ring which is corrosion resistant and strong.
The installation manual is very easy to follow with pictures in it. It comes with a one year limited warranty and a two year parts only warranty.
There are very few problems with this pump. One is that the battery, needed to run this pump, needs to be purchased separately. You also need to buy the check valve needed to be installed in the discharge pipe. Also its impeller is at the bottom and so can be clogged due to sludge. Regular maintenance however will solve this problem. The alarm is also not loud enough to be heard outside the room.
Despite its minor problems the Wayne ESP25 is one of the most affordable and powerful backup sump pumps in the market. It is the best battery operated backup sump pump.
THE WINNERS: THE BEST SUMP PUMP IN 2015
#2 – Basepump RB 750 Review: The Best Water Powered Backup Sump Pump.
The Basepump RB 750 comes from Base Products Corporation. They have been manufacturing backup sump pumps since 1999.
The Basepump RB750 is water-flow powered backup sump pump which uses water pressure from the city water supply to create the suction force required to pump water out. It has a pumping capacity of 750 to 900 gallons per hour. It needs water pressure of about 70 to 100 pounds per square inch (PSI) to work. It uses approximately one gallon of water to evacuate two gallons of water from the sump. You can purchase a backflow preventer to prevent the flood water mixing with your city water supply.
The product dimensions are 11 x 4 x 6 inches, however these do not matter as this pump need not be installed within the sump. Only the float and the suction tubes are placed inside the sump. However while installing the float, ensure that there is space around it to rise with the water level.
One of the biggest advantages is that this pump works on water pressure and does not need any batteries or power source or impellers or motors to work and hence is free from wires and any serious maintenance issues.
It comes with an alarm which sounds if the level of the water is above a certain level and the pump kicks in
The pump is made of heavy duty Polypropylene which is resistant to impact and being a plastic does not corrode. The hardware is made of stainless steel which is also resistant to corrosion. The only parts which touch the water are the float (made of plastic) and the PVC suction tube.
It comes with a five year limited warranty.
This pump does not work if the city water pressure is less than 50 PSI and a flow rate of a minimum of 12 gallons per minute. You also need to have copper water pipes; this pump does not work with galvanised iron pipes. Also if the city has installed any back flow preventers before the water pipe enters your house, this pump will not work.
Moreover, during severe power outage if the city shuts down water supply, this pump will not work.
If you don’t have to worry about batteries and power issues then Basepump RB750 with a 4.8 starts rating on Amazon is the best water flow based backup sump pump in the market.
