"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

Sewer Cleaning FAQs, answered by experts

Snaking a toilet is similar to clearing sinks and bathtubs, but there are unique circumstances where you’d have to drain, disassemble, and remove the toilet to fix the clog. For stubborn clogs in the toilet trap, a toilet auger—designed with a shorter cable and a protective plastic encasing—can navigate the tight bends and clear the clog without risking damage to the porcelain. 

Yes, many services include camera inspections to identify the cause of the blockage. Confirm with your provider.

A sewer cleanout typically looks like a white or gray PVC pipe with a removable cap. It's often located either in your yard or basement, depending on your home's plumbing configuration. The cleanout pipe is designed to provide easy access to your sewer system for maintenance and inspections. It may be flush with the ground or slightly elevated, making it distinguishable from other pipes. When you remove the cap, you can access the sewer line directly or determine its direction, which can be helpful when you need to locate your sewer line from your house to the street.

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease.
