"🚨 Avoid Len the Plumber – Negligent & Unsafe! 🚨 I hired Len the Plumber to install a brand-new water heater, but it failed after two weeks. They promised quick service but left us without hot water for days. Worse, the first technician concealed a serious fire hazard—the heater’s electrical components had actually caught FIRE and burned! A second technician finally admitted the fire risk, meaning my family could have been in grave danger. This is pure negligence and completely unacceptable. They replaced the heater but only after multiple delays, zero accountability, and putting our safety at risk. 🚫 DO NOT trust this company with your home’s safety! 🚫"

"PLEASE BE AWARE!! DO NOT USE ROTO ROOTER!! THEY ARE SCAMMING HOMEOWNERS!! My son and his fiancé just purchased their first home on Thursday, they noticed the utility sink in the basement was backing up which seemed to look like brown paper towels or cardboard when they would flush the toilets on Saturday, we called Roto Rooter to come out because we assumed the lines were clogged from the material. Roto Rooter advised it would cost $689.00 to snake the line, if they could not get the line unclogged it would be a charge of $200.00. This includes a camera to look at the pipe to make sure nothing else was damaged. The gentleman gave me a discount and charged $500.00 to snake the line, He was able to unclog the pipe. HERE IS WHERE THE SCAM BEGINS!! The Camera Man “Doug” arrives to use the camera. Immediately on arrival he says to my son, OH you just bought this house. He forces the camera down the pipe from the inside of the basement. He tells my son he has major problems, there are rocks coming inside your house through the pipes. I have a recording of the camera and we did not see any rocks whatsoever. He told us the pipes needed to be excavated and replaced. He told my son there was no clean out outside his home so that would need to be installed as well. He quoted my son $8,000.00 to dig up the yard, replace the pipe and install a clean out!!! Dough told my son he could not stay at his home; he could not run any water at all, or it would cause major issues. My son and his fiancé had not even slept one night in the house yet, they had just purchased their home. I told my son to take the estimate and tell them have a nice day!! We received a second opinion and ROTO ROOTER was totally lying!! There was a clean out right on the outside wall of the home, there was absolutely nothing wrong with the pipe besides it was slightly off which most likely has been that way for 60 years!! The second opinion we received placed a camera down the pipe, the camera went in the pipe very easily. “Doug” had to force the camera down the pipe and manipulated the camera to remove the ball so it would show there was damage when there was no damage. A day my son and his fiancé should have been happy about purchasing their first home turned into the worse day thinking they just bought a house they could not even use at all because this company wanted to try to get money out of a young couple that just purchased a new home. PLEASE DO NOT GET SCAMMED BY THIS COMPANY. There have been several lawsuits against this company for the same exact thing over the years in different states as well."

FAQs for septic system installation and replacement projects in Rockville, MD

Depending on maintenance and environmental conditions, septic distribution boxes last between 15 and 40 years. With excellent care and regular system maintenance, these components can function properly for over 30 years. Factors affecting longevity include soil conditions, proper installation, regular septic tank pumping, and avoiding excessive water usage that might overwhelm the system.

Warning signs of distribution box problems include unusually lush or soggy grass patches over your drain field, slow-draining fixtures throughout your home, and unpleasant odors in your yard. You might also experience plumbing backups, gurgling sounds in pipes, or multiple drain clogs occurring simultaneously. These symptoms indicate that wastewater isn't being evenly distributed across your leach field lines.

Most standard homeowners' insurance policies don't cover septic distribution box replacement when damage results from normal wear, age-related deterioration, or poor maintenance. Coverage might apply if damage occurs from sudden, covered events like falling trees or vehicle impacts. Some insurers offer optional septic system endorsements for additional protection. Review your specific policy details to understand your coverage options.

Septic professionals recommend having your distribution box and overall septic system inspected every two to five years. Some homeowners opt for more frequent checks, especially if they've experienced previous issues or have an older system. Regular inspections help identify minor problems before they develop into major failures requiring complete replacement. These preventative evaluations cost between $100 and $200.
