"I called Mr. Rooter because I had called another Plumbing company to come out the night before and they were a no show.  They were extremely friendly over the phone.  I called at approx 8AM and said they'd be able to come out by 11AM.  They called at about 9:30 to say someone was available to come out now and I said that was perfect.  They arrived at 10AM.

Jason was the plumber who arrived and he was very very friendly and professional.  I told him the problem and we discussed pricing up front.  I had a coupon which he said they would definitely honor.  He immediately got to work.  He wore footies over his shoes while in the house.  He worked diligently and answered all of my questions.  After about an hour and being certain the line was clear he cleaned up, we took care of payment which was exactly what was discussed beforehand, and he was on his way.

A very pleasant and hassle free experience.  I will definitely be calling Mr. Rooter for the Franklin County area again for any plumbing needs and would recommend them to anyone needing this kind of work.

The job also comes with a 30 day warranty which I thought was great and definitely put my mind at ease just in case something happened again."

French Drains FAQs, answered by experts

DIY plunging or drain cleaning chemicals may help minor clogs, but professional hydro jetting ensures long-term solutions.

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

Some homeowners use additives every month to help septic system performance, but according to the U.S. Environmental Protection Agency, the effectiveness of septic system and leach field additives is unknown. Further, additives made with organic solvents or alkali chemicals can actually be harmful to the necessary bacteria in a septic system.

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.
