"Inspection of a previously installed sump pump system (primarily the sump pump). Inspection found that it seized up and wouldn't have functioned. Replacement made - and very fortunately - since when the pump is needed, it IS needed. It wouldn't have been good to have a flooded basement or have an upcoming flooded basement."

"4 other plumbing contractors suggested I replace my sump pump becauae it was 30years old without even seeing it. Another said he would come to evaluate for349.00, but would then return to repair for an additional cost. A tenant had turned off the outtake valve causing fuse to pop. It's nice to know that there are still honest people out there. Thank you for prompt and honest service. Highly recommend."

"Our technician, Dameyan Jackson, called the night before the day of service to let me know the time that he would be here to service our system. On Friday, he called to let me know that he was available to come earlier than scheduled, if I would like. He arrived shortly after the phone call, came in and quickly recognized that the pump had failed. He was very knowledgeable and professional. I was very pleased with his service and look forward to him returning to install a new pump."

Sump Pump Installation questions, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

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.

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.

You should be fine. Most high-grade grinder pumps have a 24-hour holding capacity within the tank. You can continue to use the facilities so long as the power outage does not stretch into days. In a worst-case scenario, attach a generator to the grinder pump, providing it has sufficient electric capacity.

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.
