"E Mays Plumbing was prompt to respond to my inquiries & came within 24 hours on both occasions I requested services. During the first visit, Mr. Mays showed me how to fix the problem with the water heater in order to save me money (rather than replacing the part or the entire water heater.) After a few weeks, I decided I wanted to replace the entire unit. Mr. Mays came to my home that same day & efficiently installed the new unit & hauled away the old one. He was very professional & even asked permission to pull into my garage in order to load the old water heater onto his truck. I will definitely call E Mays Plumbing for any future plumbing needs!"

"Excellent finished product and excellent service. They installed 2300 ft.² of sod. They arrived punctually every time they said they would arrive. Extremely conscientious and hard-working, very pleasant and easy to deal with. Great communication. Afterward, I hired them for a second project, removing dead bushes and planting new ones, which they did equally as well. They are reasonably priced as well!"

"All work was done except installing the new vanity. I verbally told him I would keep the last $1000 until He came back and installed the vanity. He said he would come right over and install it when I got it in, that he needed to pay his guys for the work that has already been done. Because he said he would come right over in two or three days to install the vanity after I got it, I believed him and I paid the last $1000."

Sump Pump Installation FAQs, answered by experts

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.

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.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.
