"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

Common problems include motor failure, clogged discharge lines, and float switch malfunctions. Regular maintenance prevents many issues.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

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.

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.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.
