"The awesomeness started within a couple hours of purchasing my deal. Matt reached out to clarify a misprint in the deal, and assure I still wanted to go through with the deal. He was able to to schedule me at a time that worked with my busy schedule.
Darryl and Mike arrived right on time, first thing in the morning. I had originally purchased a hot water tank replacement deal. During the old tank removal, it was discovered that my ejector pump was not working. The crew was equipped to replace that at a reasonable price as well. They worked quick and professionally and had all the work completed in a timely manner. They made sure to have tarps available to protect my floors when moving the tanks in and out. The crew had such pleasant personalities, and I could tell they enjoyed what they were doing.
I highly recommend M&E Plumbing for any work you may need!!

"Very clogged toilet where my own plunger, nor my snake didn’t work.The plumber had it fixed in what seemed like only 5 minutes flat! I couldn’t believe it. I even used Riddix thinking the enzymes would eat thru the clog, but it only made the situation worse.Excellent plumber!!!"

"Excellent prompt affordable service.
I was contacted directly by Patrick, the owner, over the holiday weekend.
He quickly scheduled an appointment for Tuesday after the long weekend. Once he assessed the work needed, he got me a great price.
By Wednesday morning, he and his team had installed a new garbage disposal and new toilet. All the work was done quickly and while I was at work. They got everything done properly and left no mess behind. It was a seamless process and I am very satisfied with the results. I will be using them again for any plumbing issues.
I highly recommend this service.

"Brent B. showed up on time and after reviewing my existing Sump Pump situation, I decided to move ahead with the work. They were able to complete it the same day! I had researched previously and had an idea of what I wanted. Brent along with another technician completed the work, answered my questions, cleaned up, etc. Brent and Dave did a great job and will definitely use them for future jobs.

"My name's Kelly, I live in Roselle and when i called Mr.  Rooter my toilet wasn't working (wouldn't flush, water kept running).  The tech they sent out was Manny and he was such a pleasure to deal with!  He inspected the toilet and since it was a older push button toilet he said they'd have to order the pieces and actually take the toilet to repair.   Manny explained all my options and pricing,
I rent so I kept waiting to hear from my landlord (no call back) so I sent him away and told him I'd call back with my decision, before even calling Mr. Rooter I had waited a day to hear from my landlord and NO luck, so I didn't want to wait any longer.  I made the decision myself!  He wasn't even gone 30 minutes I called him back to replace it.  He showed right back up, we chose a toilet- I went with the most basic white toilet and he went out and bought it.  Installation went fast, when he was done he went thru the whole house and did a free inspection of all plumbing.  I was very happy with my service call and my son was happy too cause Manny so nicely gave him 4 magnets to keep!

Septic Tanks FAQs, answered by experts

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

If you’re going away on vacation or leaving your home for a long time, it’s a good idea to switch off your well pump and pressure tank before you go. This way you can prevent any damage from unexpected leaks that may occur or unforeseen electrical issues while you’re away.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.
