"Ian and his crew worked diligently to install a new retaining wall and walkway for my front yard. They worked through the torrential downpouring and cold weather to get it all completed before I got back from a business trip (I knew it was raining due to my view from my ring doorbell). Needless to say, everything turned out better than I could have asked for. I definitely would use The Difference Landscapes again, and I Strongly recommend them to anyone who needs some hardscaping done."

French Drains questions, answered by experts

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

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. 

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

Coke and other sodas do clean a clogged drain, so this is one of those urban myths that has some truth behind it. Coke and similar sodas are caustic and will provide some cleaning power to your drains. However, the power of soda pales in comparison to dedicated cleaners or even baking soda.
