"I submitted my request on a Sunday for a clogged toiled and they had someone scheduled for the same day in the evening. I appreciated how professional the admin was and how quickly she could get someone in to fix my issue. John S. Came in the evening and he was very professional, friendly, and helpful! He checked out my toilet, talked through things I’ve tried to do to fix it before he came in, diagnosed it and shared what he thinks is happening and other possibilities, and we talked through the price before he went in to fix it. Unfortunately what we were hoping was an easy fix wasn’t and he had to change the diagnosis and update the cost. Luckily this next diagnosis was correct and he was able to unclog the toilet! There was a small plastic cup blocking the toilet hole and he was able to take it out after pulling the toilet. He put everything back and cleaned the area. I really appreciated his help and he shared some tips to help keep things running smooth. John was great and I highly recommend him!!"

"Zach with Knock out Pluming a Seattle based company was great to work with! He did not try to "over sell" the two items that needed replacing. the toilet had a crack and the water heater had burst and it was a Sunday. I was frantically cleaning up water when Zach arrived on the scene. He not only fixed the problem right away but kindly helped me with the clean up. He came back the following day with the new water heater and toilet that did not break the bank! He was efficient, knowledgable regarding the best products to suit my needs. I highly recommend this company."

"Brian has saved us a few times from house leaks. The first time the main was cracked somewhere, pouring water into our driveway. Brian responded to our call for help very quickly, came out the same day and gave us a very reasonable bid (unlike the few other companies we called which asked for large emergency fees before coming out and didn't even have time to come out immediately - 24 - 48 hours out for a main leak!). Brian found where the leak was coming from after digging for a few hours, patched the main line, and installed a new main shut off (previously a wrench was required to toggle the water to the house), all for much less than other companies quoted over the phone. The second and most recent time Brian came out was to assess and fix a downstairs can light leaking water. Brian responded quickly and came out the same day we called. He quickly found the upstairs toilet seal was no longer viable, resealed the toilet, and cleaned out the leaky can light, again for a very reasonable price. Brian is a great plumber and I highly recommend him and his team. Thanks so much, Brian!"

Drain Cleaning FAQs, answered by experts

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.

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.
