"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

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.
