"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

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

Submersible and pedestal sump pumps are two popular types of sump pumps. Submersible models are covered by water in a sump pit, which helps keep the motor cooler and quieter. Pedestal sump pumps stick out of the sump pit, so the motor stays dry and is easier to access. Submersible sump pumps are the pricier option, but they also have longer life spans.

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

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.
