"I hired Flatirons Plumbing to install a hose bib in my garage. This required them to run a pipe from the adjacent bathroom sink, through the drywall, into the garage. Flatirons was the second quote I got for this job. The competing quote was about 50% less, but the other plumber wanted to rip out a large section of drywall to find a pipe. I would have been responsible for replacing all that drywall afterwards, at unknown expense. Flatirons was able to drill a hole in the wall, with no other drywall damage. I docked one star for professionalism, because they tracked mud on my floor and did not clean it up."

"Had them replace a drain pipe in my foundation. They were timely and efficient. Price was very good as I have been through this nightmare before. Really appreciated Keith and Nico! When Keith arrived, I instantly knew I had the right guy advising me on this. Nico did a great job doing the job. Thank you both."

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"Jason Dodge did a great job. Not only did he snake the drain in no time at all but he noticed the hot and cold water were reversed on my sink faucet and in 3 minutes he corrected it no charge! He couldn't have been nicer. I was only charged $100. for the whole thing. they have definitely become my go-to plumber!"

"Eagle did a great job at a reasonable price. I got several quotes that were way out of the ballpark (I knew this from my time remodeling homes) but Blue Thunder was right in a decent price range. Everything was done with the new kitchen sink install to a great level of quality. It looks much better than it did before and I will definitely use them on my next project."

Drain Pipe Installation FAQs, answered by experts

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

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.

If methods like hot water or a plunger don’t work on your clogged drain, you can snake your drain to dislodge the plug. This can be a messy process, taking some physical effort and additional time over the other drain-clearing options. You can purchase a drain snake at a hardware store and choose from handheld options or those attached to a drill. Just work slowly, and be ready to call a plumber if you’re unable to reach the clog from your drain or P-trap.
