"At the time I made the appointment I told I could pay by credit card however after they were done I was told I had to pay by check or cash. I called the following day to express my displeasure and to point out that not everyone has an extra $325.00 available at any given time. I spoke with one of the owners. He refused to even acknowledge they were in the wrong and instead made excuses as to why his employee couldnâ t use my WiFi to accept the credit card payment. He was extremely rude and very condescending. Instead of apologizing for their miscommunication he actually hung up on me. It appears as if this is another company that had its good reputation built by the father but has now been taken over by his spoiled son who has zero business sense and horrible customer service. I would not recommend them."

"Late on a Friday, we experienced a leaking water line behind the fridge- and the shutoff valve was broken. Sussex plumbing promised to come out, showed up on time, promptly fixed the leak and did a quick repair on the shutoff valve. They planned to come out the day before we were to get a new refrigerator to replace the faulty valve and did not charge for this urgent repair at that time. Instead Sam told us Cindy would give us a quote the following Monday that would include the urgent repair and the work required for the replacement valve. Sam showed up on time, did a fantastic job, and was very professional. The price for both jobs was extremely reasonable. We will never use a different plumber for any plumbing job we need done. Thank you for the great work!"

"We had water in our crawlspace after heavy rain. We hired Adam Basement to remedy the problem after consulting with three companies. We hired Adam Basement because of their excellent reputation in our neighborhood and because Bob of Adam Basement is a superb communicator, who explained the problem and proposed solution to us in a logical and easy-to-understand manner. Adam Basement installed a pressure relief sub-floor drainage system with a drainpipe and two sump pumps. They treated the crawlspace for mold and mildew and wrapped the floor and walls with a vapor barrier. Adam Basement’s technicians were hard-working, technically proficient, and professional, and their office staff were responsive and helpful. We’ve had the system for six months and are very pleased. The crawlspace has remained bone dry after heavy rain, and it looks and smells great. Adam Basement stands behind its work, as it provides a 10-year sump pump warranty and a lifetime, transferable waterproofing system warranty. We wholeheartedly recommend Adam Basement for basement repairs or waterproofing."

Septic Tanks questions, answered by experts

Cesspools can last up to 40 years. Their lifespan depends on the materials used, soil conditions, and maintenance of the pit. In many areas, cesspools are no longer permitted, so it’s often a good idea to get rid of a cesspool that’s at the end of its lifespan.

A household of four can easily fill a 1,000-gallon septic tank within a week. It may be 10 to 14 days for smaller households. But the reason why you don't need weekly pumping is because the tank's contents eventually reach the overflow pipe. They flow down this pipe to the absorption area whenever water is used in your home. The tank keeps working at this full level until it's pumped again.

It is not normal to smell your septic outside and indicates a problem such as an unsealed manhole or access lid, a clogged septic line, a faulty vent stack, or the need for a septic tank pumping. If sewage is leaking from your septic system, it can be hazardous to you, your family, pets, and the surrounding environment. You can troubleshoot the issue yourself, or contact a septic tank pro who can resolve the issue quickly.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

Trenches are 12 to 24 inches deep and 8 inches wide. However, the right depth for your trench will depend on the nature of your project. For example, if you’re digging a trench as part of a French drain installation, it should be 18 inches deep. An excavation professional can explain how deep your trench should be.
