"The entire process went very well.
John & the entire Moncrief staff went out of their way to accommodate our schedule, and the install only took one day.
Everyone at Moncrief was extremely professional, and the install crew did a remarkable job and even cleaned up after themselves.
This is a 'Rave Review'.

Drain Cleaning FAQs, answered by experts

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.

Once you’ve poured the baking soda and vinegar into a drain, you should wait about 10 minutes for the mixture to break down the clog. If you try the baking soda and vinegar method and it doesn't work, you can do it again or try the baking soda and salt trick.

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain.
