"I bought the new one myself, but it’s not always easy to install, and the guy was here to fix the upstairs bathroom drain needed to be fixed, so I had him do it. I get what I pay for, and they did a good job."

"Wow! Can't say enough about how amazing MB Plumbing is. I can't handle stressful situations like random leaky ceilings, long lines at the register...crying babies on airplanes..I digress. My leaky ceiling was fixed in no time and he explained everything so clearly to me. The price was reasonable and the service was prompt. I am no longer stressed (except for earlier today when my cat vomited on the rug) AMAZING MB PLUMBING! THANK YOU!!!!"

"Mike did the replacement on the hot water heater. Was very nice,professional and wanted me to understand everything. Covered the floors....I just can't say enough good about him. In this day and age to have someone come to your house and be so nice and mannerly, clean up after themselves and be there the next morning, and I called the previous night? geesh...they were wonderful! I'm very picky...you made me happy.... Lorraine B."

Septic Tanks FAQs, answered by experts

A septic perc test is done by drilling a hole into the ground, filling the hole with water, and testing to see how long it drains. While simple, the test itself provides a great deal of information about your yard. The last thing you want to do is skip a perc test only to discover your yard doesn’t drain sewage effectively.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.
