"Gregg and his team were on time, extremely professional, neat, all of the above! The quality of the job done is 100% effective. I had Hydro-static pressure and water coming in through my basement floors every time it rained, Gregg analyzed everything in a matter of seconds, gave me an absolute fair price, best in the industry, gave me a commercial quality job at my residence and even took care of relative issues that I had in my basement concerning the garage area, the level of the floor, and an old sump pump. I would absolutely recommend Gregg Segnit and Contractor's Waterproofing, Corp. for anyone's water proofing needs. He has been in this profession for years and knows what he is doing. He stuck by his word to everything he said, and actually left my basement in better shape than it was before, outside of waterproofing. Since him and his team completed the job I have not seen one ounce of water in the basement. Not one drop. Before then, every time it rained outside I would get water coming into my basement from all angles, the wall and floor. He installed in my opinion the perfect interior drain system for my home, at a reasonable price, and with a lifetime guarantee, I cannot be happier as a homeowner. I will never go to anyone else for my waterproofing needs. Thanks again Gregg and team"

"I cannot say enough good things about this company. A power outage at our house over a weekend caused a lot of damage to various motors throughout the house. Joe called very quickly after I left a message (on a Sunday!) and went through a lot of possible things to check in order to try to save my paying for a service call (much appreciated). Ended up scheduling an appointment for 8 a.m. the next morning. He was here on the dot and quickly diagnosed the problem. Fixed not only that, but helped my husband get other things restarted as well (water filter and hot water heater) before he left. The best experience ever with a service professional -- I'd highly recommend him and Old Faithful anyone with well or well pump problems."

"The technician was very knowledgeable and explained the problem and the solution options clearly. The installation of the additional equipment needed to get the heating working properly was very well done. From the initial phone call to job completion, it was a very good experience."

"Water backing up from sump pump in basement into bathroom sink pipe. Pipes snaked by said company. Told me sump pump too strong for pipes. I purchased new sump pump with less horse power. Problem still present today. Collecting water in bucket from sink pipe. I have been talking to manager of company since last Thursday. Someone is supposed to come back today. They have been very busy I am told. $350 check has been cashed as I approved because they were here last week on first visit for 2 hours and they snaked the line,but the problem still exists. Waiting for a re-evaluation today as promised."

"This gentleman is a certified master plumber. He was an absolute pleasure to deal with. I called him at about 1:30 pm and he was at our house by 5:00 pm replacing our sump pump. Not only did he complete the work as required, he made some suggestions that should end up lengthening the service of the new sump pump (which was a better pump than that replaced). He even made a side trip to pick up some supplies from Home Depot (at his own expense) that would lenghthen the service of the pump. He was pleasant, efficient, and truly cared about his craft. I would not hesitate to recommend his service to anyone."

"Sergio responded within minutes of my home advisor inquiry. He set up an estimate and evaluation within 90 minutes and he and his assistant were able to perform my required work later that afternoon. The required work on my gutters was performed, and I was briefed on a noted deficiency that will soon require attention. The work needed was a small maintenance necessity, did not take much time, and the price quoted and charged was acceptable! Sergio and crew were very professional, they briefed me on all aspects of the work performed. Granted, their response on this day was unique, but if I had to make an appointment, I surely would have. Yes, I would hire them again. Well done Marine!"

Sump Pump Installation questions, answered by experts

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

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. 

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. 

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.
