"I overfilled my garbage disposer!! My sink had 2 inches of water as a result of my trying a plunger to clear it. I called RS Plumbing at 4:45 in the afternoon and Steve came the next morning at 8:00.

He had me clear the area around the basement pipes in case the clog was more major than I hoped. He was able to clear the drain only in the kitchen area. He worked efficiently and had the drain running freely. I asked him to check the dishwasher hosing in case that was part of the blockage. I have had problems with that before.

RS Plumbing was prompt, competent, and overall good to work with."

"Serviceman said noise was from drain motor. Price of new motor and the service call would be $200+. We said thanks, declined service on this 6 year old Bosch and went out and ordered a new one. Cost - $1100.00 to be delivered in 2 months. We are grateful that the old Bosch is still running. We have had other issues with this particular dishwasher. So much so that the Lowe's maintenance contract was cancelled by their warranty provider with a full refund of the warranty cost. The warranty company said it would be too expensive for them to continue servicing our Bosch!"

Drain Cleaning FAQs, answered by experts

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

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.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.
