"Honestly, I have never had such a positive experience with a contractor. they showed up on time, were friendly, polite, courteous, clean and efficient. In a single day they installed the entire system and left the place clean (within reason). This included jack hammering more than 30 feet of concrete floor and complete water ejection. Unbelievable. They will never be the cheap solution, but they are worth it!"

"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

"Outstanding! John took our vision and brought it to life in a way that went beyond anything we could have imagined. What could have been a simple repair turned into a complete transformation. The stonework they created not only improved the look of our home but made it stand out in the neighborhood. People keep stopping in front of the house to admire it. The quality, craftsmanship, and attention to detail are second to none."

"Jonathan was a lifesaver. The well circuit breaker had flipped earlier that morning. I called plumber because there was no water. The series of evenst that followed were horriffic. Plumber had flipped the well switch back, turned on the water and left. Neighbors called to tell me te basement windows were pumping out smoke. The fire deprtment came and shut everything down. I contacted Johnathan as a well specialist. That he is. He troublshooted the problem. The well switched tripped. The pump was burned out, fire, pressure valve and fittings melted. He replaced the hot water heater, all fittings and new pressure pump installed. I give Jonathan R. Habacker Pumbing, LLC the highest ratings possible. He also pointed out other future issues. I will be having him install new hot water heater, well serviced and/or replacement. HE is my only contact for well and plumbing issues. Make him yours. With much respect for quality work. Carol A. Whelan"

French Drains FAQs, answered by experts

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

You should inspect and clean your French drain at least once per year to keep it in good working order. Regular maintenance can help identify clogs, buildup, and damage before they become bigger problems, which increases the lifespan of your drain. The frequency with which a drain clogs can depend on factors like the amount of debris, the quality of the installation, and the type of filter used. If your drain accumulates a lot of sediment, it may require more frequent cleaning. It's also a good practice to check the access and exit points after heavy storms. If you notice reduced drainage or any signs of a clog, clean the drain as soon as possible.

Baking soda and vinegar aren’t just great for making a volcano for your kid’s science project. You can also pour this dynamic duo down your shower drain to dissolve hair clogs. If that doesn’t do the trick, you can step it up with a commercial liquid drain cleaner. 

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
