"There's no arguing with the results. They removed the old sewer line and water line and replaced them with new lines. Both work to perfection. The only thing keeping this review from being a five star sweep would be the degree of professionalism exhibited by one of the team members. I believe once they work out the kinks they will reach five stars across the board. Rob, Logan, and Michael worked together very well and I would definitely refer them to anyone needing this type of major repair."

"Each job was done professionally. The tub faucet was over 25 years old and he knew where to go to get the replacement parts to get it fixed. He really knows what he's doing. The water heater he picked out for us is top of the line. We are very grateful for the fine service we got."

Drain Cleaning FAQs, answered by experts

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

The spin cycle on your washer should initiate draining, but if you still find leftover water in the washing machine tub, you may need to drain it manually. To manually drain a washing machine, you’ll need to turn off the power supply and locate the drain hose, filter, and pump. Open or disconnect these parts and let the water drain into a bucket.

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.
