"These people responded almost immediately to my request to clear a drain blockage. When the drain clogged again two days later, they came back immediately and snaked another part of the system successfully curing the problem. The revisit and work was free of charge. They even apologized for not permanently clearing the drain the first time. They were extremely nice and courteous and I would recommend them highly for any plumbing or sewage problem."

"Our shower suddenly stopped draining. We contacted ANGI and were given this company’s information. They called and said they could come right out. The repair tech was there soon and fixed the issue quickly and completely. He even cleaned the area when he finished. We were very happy with this company and will probably call them again for future repairs."

French Drains FAQs, answered by experts

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.

If the drain pump on your washing machine is continuously draining, it could be that the control board is damaged and requires repair, or there’s a clogged or kinked drain hose. If you can’t locate the problem, you’ll want to have a plumber or appliance repair expert come take a look.

You can unclog an AC drain line for free if you already have these household ingredients: water, vinegar, and rags. Alternatively, if you’d rather not deal with the mess, you can hire a pro to clear your drain line. If you go that route, an HVAC service call costs between $100 and $250.

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.

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.
