"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

A liquid drain cleaner can sometimes make a clog worse over time if you use it improperly or too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that may cause further blockages. If the clog is more than the liquid drain cleaner can handle, the cleaner will simply add chemicals to a bigger overall problem.

It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.

Yes, pop-up drains commonly get clogged with hair, soap scum, and toothpaste. It is important to know how to properly clean the drain or get professional help to ensure it remains clear and can drain water effectively.

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

You’ll likely pay between $300 and $450 to unclog your toilet with Roto-Rooter. However, the price could change depending on if the clog has caused a lot of damage, which your plumbing pro will want to inspect during your service appointment. Keep in mind that you won’t get a quote from Roto-Rooter over the phone. They have to send a pro out for an in-person cost estimate. You can also attempt to snake your own clog for a lot less, and simple drain snakes cost no more than $50.
