"Had them pump my septic. Quoted me $550 before tax. Charged me an extra $100 to break up the top solid layer, which is a little deceptive since that layer is always there. Will go with FloHawks again next time, they didn't charge me an additional fee to break up the top layer last time I had my septic pumped."

He got right to work identifying key issues and provide multiple options. Found out that we had an sump pump that failed and recommend we replace that 1st. Everything was replaced and tested within 40 minutes."

"The seal for the master bath toilet was leaking which he replaced. I was concerned about the shower leaking which he checked and offered to replace the cartridge, but in his opinion didn't need it and showed me why. He also checked the sump pump, which actually was working. Noel was friendly, polite, efficient, and had everything he needed to do the repair on his truck. He gave me an estimate before beginning the work. I'd definitely hire again."

"We were in a jam. We are attempting to buy our first home. We had our inspection scheduled and on the morning of, we learned of a potential plumbing issue. There was a report filed with the city stating that a couple of years ago there was some kind of sewer back up. This house is old, so I wanted to make sure we weren't signing up for any potential problems. I called around to local plumbers in the area. NONE of them were able to accommodate our need on this shortened time frame. I got Zach's number from a contractor friend of mine and in a last ditch effort gave him a call. Unlike some of the other plumbers I'd spoken with, Zach validated my concerns and informed me that he would recommend that I have my system inspected. He was very patient with my partner and I, making room for us that evening to show up in exemplary fashion. He did a full inspection of our sewer lines with a camera and explained to us what the different piping meant. He then tested our water pressure and advised us to request that the seller offer concessions to cover the cost of putting in a pressure reduction valve. He explained the reasoning behind his recommendations and took time to insure that we understood why he was recommending these services. He also took the time to explain and answer questions about potential upgrades as my partner wants to upgrade the hot water tank. He outlined different product options and explained with great knowledge and detail the differences between the products. I would highly recommend this company. If we get the home we will definitely be having this company come back and preform the necessary work that is needed for our new home."

"Diagnostician/Estimator and Plumbing team were just excellent. Sewer work and team very good, but also very pricey. Repairs on system were well done - crawlspace access area was damaged to extract the old sewage tank. Damage is still being repaired by homeowner. Harts rebated some cost to cover access damage. All Harts team members were fully vaccinated, wore masks, and were great to work with. Harts completed work within 1 day within quoted costs. New sewer pump alarm system system malfunctioned right after the install was finished - Harts sent a repair tech out to fix it on next day - excellent service - fixed the twisted tank float problem - no charge. Building inspector noticed new sump pump was tilted and alarm wiring was not properly affixed to the house - minor issues, I would hire Harts again but negotiate hours and pricing ."

"Gardner came to do an inspection of my basement and provide a quote. I had received other quotes that only provided for a single sump pump install at outrageous prices. He was very thorough, took two hours to measure, inspect, provided videos and explanations on everything, and the quote was shockingly affordable with so much more work I was ecstatic! I am getting a three sump pump with back up battery, and so much more for basically what the others quoted. And, to have the option to finance through Greensky was the cherry on top! If you are in King County, ask for Gardner @ GROUNDWORKS - you won’t regret it!"

Sump Pump Installation questions, 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.

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.

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.

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.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.
