"Robert was an amazing plumber to work with. Extremely professional, knowledgeable, responsive and honest. All traits that are hard to come by in this profession. Ever since I found his business, Iâ ve never even bothered to look elsewhere. He never tries to upsell you, gives you options and always cleans up meticulously. Iâ ve recommended him to all my friends and family and they were all happy with his services. So far heâ s fixed my clogged sink, installed and repaired my garbage disposal, came immediately when my storm drain busted, and gave me quotes and advice on a tankless water heater. Hopefully I wonâ t need his services any time soon though!"

"**Robert was very calm, cool, and collected!!!! I got a call from my tenant at about 1p on a Sunday afternoon, that her kitchen ceiling was leaking water. I suspected there was a plumbing issue right away, and I reached out to Robert. Instantly, Robert said he would go take a look after he completed his job across town. Heroically, Robert made it there in about 30 mins and discovered the issue was a clogged pipe, and used all his tools in his belt to help me clear the clogged drain issue. Long story short -- he fixed everything before 3p 😮😮😮 Thank you Robert!! You are the man!! I will call you without hesitation moving forward!!!"

"We highly recommend Green Arrow Plumbing. Our clogged drain was due to the corroded cast iron drain pipes original from 1957 and Cornelio replaced them in short order. While he was here, he also fixed two toilet flushing problems which two handymen had been unable to do. Cornelio was very knowledgeable, his rates reasonable, and it was a pleasure to work with him."

"We've been working with Mike Counsil for over 8 years - clogged drains, water heater, new toilets, and most recently a sewer re-pipe. Yes, they may be more expensive than other companies, but with Mike Counsil you get what you pay for - quality work. A big shout out to Rudy and the whole team - they are hardworking, reliable and courteous."

Drain Cleaning questions, answered by experts

If you try a drain snake and various DIY methods for unclogging drains to no avail, bring in a professional plumber to assess the situation. Also, if multiple drains in your home are backing up or you smell sewage, a visit from a plumber is best. You can expect your drain cleaning costs to fall around $250, and this can include an assessment of what’s caught in your plumbing and if there’s a larger, underlying problem. You should also consider calling a pro if you need to snake a toilet, as DIYing this could lead to a cracked fixture.

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.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

Although linear drains allow water to flow quickly and efficiently, they tend to clog more easily than traditional drains. Linear drains are flush with the shower floor, allowing soap scum and hair to potentially build up. They’re also longer than other drains, allowing for more space to let debris fall into the drainpipe. 

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