"Justin responded to my call promptly and set up a time to come to unclog my cellar sink. He was courteous and professional. He is insured and very reason as ble. He spent 3 hours trying to unclog my drains. It turned out that the problem was with the city's sewer system. I would definitely use him again and highly recommend him! He is a great representative for the plumbing industry."

"I was experience a sewer back up in my basement, the tech came within an hour. Extremely professional, knew exactly what he was doing. Cleared the line and showed me a bunch of roots, explained he could use high pressure water to get em out, I called roto rooter two years ago and they didn?t even mention the possibility of that, they told me it would be 14k to dig it. I gave the guy the okay to clear the line out with water, and I can?t believe he got the line looking brand new. Professional, affordable, left the place cleaner than when they came, would 100% recommend them."

"John installed a new bathroom faucet, sink drain, supply lines and shutoff. He showed up on time and gave me a quote which I accepted. He said he could do the work right away and an hour and a half later he was finished. He was very pleasant to work with and I'm planning to have him do more work for me. His business card is now the only plumber I have on my refrigerator."

"I'm extremely happy with the service; Rooterman came by on a Saturday to provide an estimate. He said he'd be back on Monday between 11:00 AM and 1:00PM. He arrived just before 11:00AM. He was efficient and neat. We had the kitchen faucet replaced and 2 hand held shower heads put in the bathrooms. He also unclog a drain. I would definitely recommend Rooterman."

"My bathtub drain was clogged. Unfortunately, my trusted plumber of many years had retired and moved away. I looked around on the internet and somewhat randomly chose Fellowship Plumbing & Mechanical to call. Kyle showed up the next day and went to work with his power auger. Unfortunately, the bath being on the second floor resulting in lots of pipe twists and turns, the auger was unable to make the turns required to unclog the trap. The possibility now came up that he might have to come up through the ceiling on the first floor to unclog the pipe. That would have likely resulted in damage to the kitchen cabinets. So the possibility was there that this would cost me many thousand of dollars and great inconvenience. But "Wait" Kyle said, "I've got one last chance possibility". He left my house and returned a while later with a chemical only available to contractors. After 15 minutes or so, I heard a gasp of joy and the pipe was unclogged. The water is now draining at a rate not seen in years. Kyle recommended that I replace the bathtub drain strainer cover with a hair catcher strainer, which I have done. So, hopefully, I won't need a plumber in the foreseeable future, but if I do, I'll definitely call Fellowship Plumbing & Mechanical."

French Drains FAQs, answered by experts

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

Costs vary by severity and access requirements. Typical pricing ranges from $100 to $350, increasing with complexity or for emergency services.

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.

Drain fly problems can go away on their own—but only if the insects find the environment inhospitable. Those with a minor infestation can simply flush their toilets and run their faucets more frequently to flush out the flies and larvae. Others will have to deep clean their drains and set up traps.

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter.
