"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

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.
