"I've given A-DRAIN PLUMBING 5 Stars. I only wish I could give them 10. A-Drain Plumbing came to my rescue when every other Plumber in town was just too busy. With -40 temperatures pipes & waterlines broke all over & around town. I called & let them know I lived outside of town in the country & my main water line had broke. They looked at their priorities & fit me in As soon as they possibly could. I received a call back unexpectedly right away & texts letting me know where they were & how soon they could come help me. A-Drain Plumbing completely know their business. Kind, courteous & extremely experienced. 10 Stars from me! Thank you A-DRAIN PLUMBING!"

"Joe from JMS Drain Services was my service technician who arrived well within the window scheduled service time. Joe came in, inspected the sink to determine how to resolve my issue, took out the tool (snake apparatus) to clear the sink, and departed my premises within 15 minutes. I was pleased he resolved my clogged sink so quickly so I could rest after a night's work. Thank you again, Joe."

Drain Cleaning questions, answered by experts

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

If you don’t have a sewer cleanout, clearing out clogs can be extremely difficult. You would need to try to clear the clog from sink drains, but it can be harder to reach the clog all the way in the drain line. A sewer cleanout makes it much faster and easier for pros to clear clogs from your main sewer line.

The spin cycle on your washer should initiate draining, but if you still find leftover water in the washing machine tub, you may need to drain it manually. To manually drain a washing machine, you’ll need to turn off the power supply and locate the drain hose, filter, and pump. Open or disconnect these parts and let the water drain into a bucket.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages.
