"I had a great experience with Conger Plumbing (Mr. Rooter Plumbing). From start to finish, they were professional, courteous, and knowledgeable. They showed up on time, clearly explained the issue, and took the time to make sure the repair was done correctly. The quality of their work and attention to detail really stood out. It’s refreshing to find a plumbing company that truly cares about their customers and stands behind their service. I would highly recommend Conger Plumbing (Mr. Rooter Plumbing) to anyone looking for reliable, honest, and professional plumbing work."

"Couldn't identify project accurately from dropdowns: fixed my crawlspace and installed a dehumidifier. The team did an excellent job and finished in about 1/2 day. I can highly recommend the company AND the team (Shane English - foreman, Luke Bolinger, and Riley Lane). Happy Customer!"

"called company regarding foul odor in bathroom. Owner gave advice over the phone, and offered to come to the house then, or the next day if problem was not resolved. We followed his advice, problem resolved, and his visit was not required. This suggested to me that he was interested in a happy customer, not making a house call just for the money. I'll call him again if I need a plumber."

French Drains FAQs, answered by experts

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.

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.

When you put baking soda and vinegar down the drain, they chemically react and help break down clogs. It’s not going to work for every type of clog, however. For example, it’s not the best way to get rid of grease buildup. For grease, you should try boiling water and white vinegar instead.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.
