"Robert and his team saved us from an emergency with groundwater flooding under our house. I called them at 8pm and they were out within a couple of hours that night and worked until midnight to install a sump pump. They did excellent work and were very communicative about the work they were doing. I highly recommend Facilities Plumbing."

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"Fito Plumbers installed a new sewer line at my house. I appreciate good customer service when I see it, especially when it is with a contractor. My experience with Fito Plumbers was a positive one from the very beginning. From the quote, all the way through the final signoff Fito's team was great. Fito was honest and kept in communication with me over the one month period that it took to get the permits. His team showed up when he said they would, they were courteous and they respected my property. They did not kill one plant on my property which is a first. They cleaned up at the end of each day and they restored the pavers to the point where I can not tell where they had to remove them. I also appreciate that Fito's team power washed all the utility paint markings not only on my property but in the street. My street is covered with paint from previous work by others. Overall, Fito Plumbers was competitively priced and went beyond expectations with the installation."

Sump Pump Installation FAQs, answered by experts

First, you can try unplugging the two sump pump cords, one for the motor and one for the float switch, then plugging them back in to reset the sump pump. You can also reset the sump pump by turning it off and back on at the breaker. Many sump pumps have a reset button, which you can press and hold for a few seconds to reset the device.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

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.

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.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.
