"Marchett came over to install the water filter that was in back order when the water system was installed a couple months ago. He saw that it would be awkward changing the filter in the location where it would fit, so he suggested rearranging the entire system to make it easier, which he then did. Very respectful throughout and led me through the process of changing the filter, which doesn‘t require Turing off all of the water in the house. Efficient product and great service!"

"I forgot to do this review but am glad I did because I am two years out having waterproofing services by this company. The drain and sump pump recommended by Robert Ellis is absolutely worth it. I no longer am anxious about weather forecasts because of the work done. Robert evaluated my home, gave me options and soft recommendations then allowed me space to make the best long term decision. Completely satisfied and would recommend."

"Tommy B was efficient and courteous. I knew who to expect since I got the name and a photo of the plumber in a text. He covered his shoes upon entering the home. He gave the price for parts and labor upfront. He replaced my old sump pump with a new Zoeller Sump pump. As he was working he patiently answered my questions. He cleaned the work area thoroughly. Excellent job."

Sump Pump Installation FAQs, answered by experts

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.
