"Sump pump died and water overflowed on weekend. Renz spoke with us promptly on the phone, came to the house, installed pump for reasonable cost (in accord with our telecon), taped the pump's electrical wire to make a "neat" job, checked outflow pipe and drainage, and cleaned up the work area fairly well. Weeks later and no problem."

"We have an old house (100+ years old). I called Atomic Rooter to fix a bad clog and reconnect drain pipes. They responded quickly, came the next day (as agreed), on time, professional, clean and upfront price. For plumbing services, I think they were very reasonable. Larry and his assistant were great. I will use them again."

Drain Cleaning FAQs, answered by experts

Your clothes—and your washing machine—will send you a few signals if you’re overdue for cleaning your washing machine filter. If you notice a buildup of detergent residue on your clothes, your clothes don’t dry quickly or at all, or you’re noticing lint in the machine, it’s time to clean the filter. 

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.

As with many appliances, proper maintenance is key to maximizing your garbage disposal’s life span. If everyone in your household is on board with proper care and maintenance, like running water while operating the disposal, you should get plenty of years out of your unit. Avoid putting the wrong food items down the disposal, including pasta, rice, bread, and more.

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary.
